Lesson Overviews

Lesson 1


MC awakens inside the assembly hall where the officers of the student council hold official meetings, first greeted by Diavolo, the ruler of the Devildom. Diavolo welcomes MC to the Royal Academy of Diavolo a.k.a. RAD. MC is interrupted and introduced to Lucifer who is the Avatar of Pride, the vice president of the student council and Diavolo’s right-hand man. Lucifer welcomes and explain to MC that Diavolo believes that demons should start strengthening their kind’s relationship with both the human world and the Celestial Realm. Lucifer states that they have sent two of their students into the human world and two on the Celestial Realm. MC is one of the four students welcomed to RAD, two which came from the human world and another two from the Celestial Realm. MC’s period of stay is one year, where they would have to work on the tasks received from RAD; after that they would have to write a paper about the their exchange program in the Devildom.

Lucifer introduces MC to his brother Mammon who is the Avatar of Greed. MC is also given a D.D.D a lot like a cellphone in the human world. MC calls Mammon through an outgoing call, repulsive of the idea being in charge of the human and does not believe MC; Lucifer snatches the call and threatens Mammon to come. MC is then introduced to the other brothers of Lucifer; he first introduces Asmodeus, the fifth eldest and is the Avatar of Lust. Second, he introduces Satan, the fourth eldest and the Avatar of Wrath. Lastly he introduces Beelzebub, the sixth oldest and the Avatar of Gluttony. Lucifer states that there are seven brothers and he is the eldest, he also explain that Mammon is the second oldest brother and will be joining them soon. Diavolo states that the brothers will keep MC safe and would also be staying with them in the House of Lamentation. Lucifer gives MC a way to communicate with the others by handing out their phone numbers in your D.D.D

Mammon arrives at the assembly hall and Satan introduces him as the Avatar of Greed, Lucifer punches Mammon for threatening MC. He is ordered by Lucifer to be in charge of MC during the whole exchange program. Lucifer then explains MC’s tasks which is to polish your soul nicely for demons likes humans with nice souls and said that other demons at RAD also have tasks assigned to them. Lucifer also states that MC would not be doing the tasks alone for the human does not posses any magic like the other exchange students in the human world, so MC is lent with powers possessed by the brothers. The tasks consists mainly of dance battles, and to use the powers lent by the brothers you must use special cards, these cards could be summoned through the app in the D.D.D called Nightmare. Diavolo states his dream where Humans, angels, demons in a universe accepts the other and brought together as friends.

MC arrives at the House of Lamentation with Mammon; he states that it is also the only dorm that is reserved for the student council members. Diavolo has his own castle so he does not live among the brothers. MC meets Leviathan, who's the Avatar of Envy and the third oldest brother. The two get into an argument where Leviathan states that Mammon owns him money to buy a Blu-ray box set. Mammon uses MC as a distraction to get away from Leviathan, he later send MC a text that he had some business to take care of.

Leviathan drags MC into his room, he is revealed to be a huge otaku and calls other people normies; he is also a fan of the series the Tale of the Seven Lords (aka TSL) as he goes on a rant about the series. Later he explains to MC that he lent Mammon money and wants him to pay it back. Leviathan tells the story why he hates Mammon; it is revealed that Mammon won a prize in a convenience store promotional campaign, if they bought something they could reach into a box and pull out the grand prize to be Seraphina figurine. Mammon refused to give the figurine to Leviathan so he snuck into Mammon’s bedroom only to find the figurine just lying on the floor gave Leviathan threw into a fit and attacked Mammon. Leviathan advises MC that a human can make a pact with a demon and bound him to service, and making a pact with Mammon ordering him to give his money back. Leviathan then explains to MC his plan on how to make a pact with Mammon by having some leverage.

Lesson 2
The lesson starts with 2 passerby demons gossiping about MC. MC meets Solomon for the first time, an exchange student from the human world. He hands MC their dropped D.D.D. and leaves. MC then runs into Lucifer, and remembering Leviathan's advice, discreetly asks him about the whereabouts of Mammon's precious credit card, Goldie. Lucifer gives MC a hint as to where Goldie might be, which (in the hard lessons) causes quite a bit of discussion between Solomon, Asmodeus and Satan. Asmodeus says that Lucifer have taken a liking to the MC. It's mentioned in the story that Solomon was already in a pact with both Asmodeus and Barbatos.

Later on, Leviathan messages MC to go to the kitchen, having a hunch about where Goldie's hidden. Beelzebub is eating in the kitchen as usual, and MC asks him who's the seventh brother. Beelzebub warns MC to never mention him in front of Lucifer. Leviathan finds Mammon's credit card in the freezer after Beelzebub leaves. But Mammon shows up then, and after he sees Golide, he even goes down on his knees to get Goldie back. He also agrees to make a pact with MC when Leviathan threatens to tell on Lucifer. The next day, the brothers laugh at Mammon and tease Leviathan that he was won over by the MC. Unfortunately, Lucifer walks into the dinning room while Mammon is criticizing him. The brothers continue to tease Mammon even after he's hit by Lucifer. Mammon stomps off with MC and claims that he would not care if MC got eaten by some demon in RAD. MC commands Mammon to 'stay!' and true enough, he could not leave.

At RAD, MC meets and chats with Diavolo and Barbatos, Diavolo's steward. Simeon and Luke (the two angel exchange students from the Celestial Realm) also join the conversation. Both Diavolo and Lucifer makes fun of Luke, calling him a 'chihuahua'. Luke retaliates by saying that he reports directly to Michael the Archangel, implying that he is a high-ranked angel. When MC is left alone with Luke, he warns them to never trust a demon, especially when that demon is Lucifer. The first bell rings and they part ways.

Later that night, MC hears someone calling for help. When they followed the calls, MC reaches a staircase. Before they could climb the stairs, Lucifer appears and tells them to go back to their room. The lesson ends with MC's flashback on Luke's words to never trust a demon.

Lesson 3
The following night, MC tries to visit the staircase, only to be blocked by Lucifer again. Lucifer emphasises that MC should not try to go up again. MC comes to the conclusion that they would not be able to reach the top of the staircase unless something is done to Lucifer.

The next morning, Mammon eats breakfast with MC and says how much he would like to eat MC. He then goes on to critize his demon brothers, like how Leviathan's haircut is so lame and Satan's horns look stupid. Mammon refuses to leak any information when MC asks him what was at the top of those stairs. MC then taunts and makes fun of Mammon, and in his rage, he says that Lucifer can be distracted with a vinyl edition copy of the TSL soundtrack. MC uses the power of their pact to drag Mammon to Leviathan's room to get the soundtrack.

As MC and Mammon discuss how to get into Leviathan's room, Solomon appears, invited by Leviathan to his room. Solomon manages to enter Leviathan's room using a secret phrase as proof that he's a TSL nerd, leaving MC and Mammon outside. Later that night, MC, Mammon and Beelzebub (who's only there for the popcorn) keep a 'TSL Full Series DVD Marathon Night' that lasts for 12 hours. The next day, MC competes with Leviathan to see who is the biggest TSL fan. Before that, MC meets Beelzebub and Satan, who both give them tips to win. Beelzebub suggests to work Leviathan into a jealous frenzy, and Satan tells MC to ask Simeon on the unreleased contents of TSL. On the day of the competition, Diavolo acts as the judge, Satan as commentary, Beelzebub as guest demon and Asmodeus as the host. Asmodeus asks easy questions from MC, and hard ones from Leviathan. MC proceeds to pull out their trump card, ending the lesson on a cliffhanger.

Lesson 4
If MC went to Simeon for advice, they'll reveal the summarization of the major plot developments in the as-of-yet unreleased TSL Volume 9. Leviathan thinks that MC is lying until Diavolo, who has the ability to discern whether someone is telling the truth, confirms that MC was telling the truth.

If MC went to Solomon, they'll reveal a single winged pendant. Turns out its a rare version of the Lord of Corruption's lost wing only sold in limited quantities with the release of the first TSL volume. The sight of it sends Leviathan to tears.

Either choice, the trump card works and Leviathan goes into a jealous frenzy, revealing his demon form and advances to MC. Mammon tries to save them, but he isn't quick enough. Just as he's about to attack them, Lucifer changes into his demon form and stops Leviathan. The brothers (particularly Satan) remark on how Lucifer rescued a human. Without Leviathan to continue the competition, Diavolo declares it a tie. MC is then taken back to their room by Mammon and Beelzebub. Mammon bandages their wrist while complaining and the two brothers bickering on how they've been spending a lot of time in MC's room since the movie marathon. Beelzebub then states that Mammon isn't doing a good job on bandaging their wrist all the while eating the pizza they brought in (including Mammon's slice). After Beelzebub leaves to get a soda, Mammon tells MC the next time he's going to be the one who saves MC. They then get a call from Leviathan to meet him in the Planetarium.

Later, Beelzebub catches Mammon searching MC's room for things with monetary value, wanting to sell MC's uniform and claiming that he would even sell MC if there was any profit in it. Beelzebub comes to the conclusion that Mammon likes MC so much, he can't help but dig through their things. Mammon becomes desperate to deny it. Beelzebub takes a picture of Mammon smiling at the thought that MC likes him and sends it to the demon brothers.

Since Leviathan now views MC as the bigger TSL fan, he keeps his promise to enter a pact. MC borrowed Leviathan's TSL soundtrack successfully, and lends it to Lucifer. He told MC that he would not leave his room that night, but warns MC not to climb the stairs to the attic. However, MC climbs the stairs and finds someone trapped in the attic, saying that he was a human just like MC. He says that Lucifer imprisoned him in the attic long ago, and he's been stuck there ever since. He asks for MC's help to free him, and in order to do so, MC needs to form a pact with Lucifer and his six brothers to obtain their consent. He tells MC to go for Beelzebub next. The next morning, Lucifer asks MC what they had done last night, and told them to just focus on surviving in the Devildom and return to the human world at the end of the exchange program. Later, MC, Mammon and Beelzebub meets Simeon and Luke, and the angels invites them to a camping trip. Later that night, MC lies in bed thinking about what the stranger in the attic had said, when they received a message from Mammon telling them to meet him in the kitchen. Mammon finds Beelzebub's custard in the fridge and urges MC to eat it. MC eats Beelzebub's custard, and Beelzebub appears in the kitchen, asking angrily if Mammon ate his custard. Lesson 4 ends with Beelzebub revealing his demon form, not believing that his custard was eaten.

Lesson 5
MC, Mammon and Beelzebub are in Lucifer's room as Lucifer lectures them on what they had done wrong. The kitchen has been destroyed when Beelzebub went on a rampage, and since MC's room was on the opposite side of the wall, MC's room now lacks a wall. Lucifer tells them that MC would be staying in Beelzebub's room for the time being - much to Mammon's objection against the idea. There are two beds in Beelzebub's room. The bed on the left belongs to Beelzebub, and the bed on the right belongs to Belphegor, Beelzebub's twin brother. Belphegor's said to be in the human world as an exchange student along with another demon, Diaval. The brothers used to have a sister, Lilith, who was especially close to Beelzebub and Belphegor. MC later realizes that the occupant of the attic room is actually Belphegor when they see a portrait of Belphegor in the portrait room. MC goes back to the attic and true and he indeed is Belphegor, the Avatar of Sloth.

The next morning, MC eavesdrops on a conversation between Lucifer and Beelzebub on how Belphegor has been and that Belphegor had tried to stand in the way of Diavolo's dream. It seems that the demon brothers were originally angels up in the Celestial Realm and Lucifer had pleged loyalty to Diavolo when they ended up in the Devildom. MC decides to help Belphegor in order to resolve the conflict between the twins and Lucifer. Later on, Luke messages MC that he's outside the House of Lamentation and he needs to spend the night in MC's room. Since MC's room was destroyed by Beelzebub, Luke has to stay with MC in Beelzebub's room. During breakfast, both MC and Beelzebub eat less than usual, wanting to bring the food back for Luke. Beelzebub having uneaten food left on his plate causes a commotion between Mammon, Satan and Asmodeus. On the way back to Beelzebub's room, Luke is spotted roaming the hallway and looking inside rooms like Satan's. He manages to see his room as well as Purgatory Hall from the House of Lamentation. Back in Beelzebub's room, Beelzebub announces that Lucifer is having a surprise inspection to check if anyone is out past curfew. Lucifer also checks inside the room itself, and finds a witch that had transformed into a spider in Asmodeus' room. Beelzebub shoves Luke into a closet, where Luke has disappeared from when Lucifer orders for it to be opened. Luke doesn't come back that night. The next day, Simeon asks MC and Beelzebub to take care of Luke until he is ready to go back, but both MC and Beelzebub can't tell Simeon that Luke had disappeared. Later, Beelzebub and MC searches around the house but still can't find him. They meet Satan on the way. When they reach the entrance hall, they see that the decorative dollhouse of the House of Lamentation has an extra room in it; a room that does not exist.

Lesson 6
MC and Beelzebub finds a secret room, a copy of Lilith's room back up in the Celestial Realm. MC asks Beelzebub to know more about Lilith, and he described what happened during the Celestial War. Mammon suddenly calls MC and tells them to hurry to the underground tomb. Turns out Luke has somehow ended up at the undergound tomb where he found the grimoire. Lucifer has noticed his presence, and gets furious at the sight of Luke holding the book. When MC and Beelzebub arrives, Luke accidently admits Beelzebub hid him in his closet, to which Lucifer demands an explanation from Beelzebub. However, he doesn't give Beelzebub a chance to defend himself, warning Beelzebub and Luke that they should get ready to face the consequences. MC then decides to step between them, shielding Luke and Beelzebub. Lucifer, surprised by MC's bravery, tells them that he can only save one of them. However, MC says they want to protect both. Outraged by MC's reply, Lucifer gets ready to attack MC, when they pass out. Later, MC wakes up to Beelzebub calling their name. They're back in the twins' room. MC asks what happened, and Beelzebub explains that Diavolo's arrived in time and was able to stop Lucifer. Luke was shaken up and Simeon took him home, but otherwise wasn't injured, neither was Beelzebub. Then he tells MC that he's the one to blame for what happened before and asks MC why they tried to protect him and Luke. MC tells him their body moved on their own or that they're important to MC as they're friends. Beelzebub tells MC he wants to do something for them as a thank you. MC asks him to make a pact with them. Beelzebub asks why they want to make a pact with him and his brothers, to which MC reply is either to impress Lucifer or help him make up with Belphegor. Beelzebub agrees that he also wants the two of them to make up. He also takes MC to Hell's Kitchen to eat, but Mammon and Leviathan tag along. The four eventually talk about why MC wants to make a pact with the brothers and Mammon and Leviathan join in on the operation. When they got back to the House of Lamentation, Lucifer appeared and told MC that their room has been fixed. On the last night staying in Beelzebub's room, he held MC's hands as he tries to fall asleep. That night, he had a different dream from what he usually has.

The next morning, breakfast with the brothers was awkward and uncomfortable. Just as MC was about to head off to class early, Lucifer told them to meet him in the music room. A conversation occurs and Lucifer wants to treat MC to a meal to make it up to them. Later in the student council room, Diavolo announces an exchange party between demons, angels and humans to be held at the Demon Lord’s Castle. They will spend several nights there and attend several events such as a dinner party and a formal dance. MC goes to the attic and Belphegor tells MC to search for clues why they were chosen for the exchange trip at the retreat.

Lesson 7
MC and the demon brothers arrive at the Demon Lord’s Castle, followed by Solomon, Simeon and Luke. Barbatos explains that there would be a tour around the castle and different cusines would be served on the three different days: Devildom cusine by Barbatos, Celestial Realm food by Luke and the Human World food by MC (for lunch on the last day). There would be a scavenger hunt on the second day along with a dance after that. Barbatos proceeds to assign rooms. MC shares a room with Simeon and Asmodeus. Mammon demands to switch rooms with Asmodeus, and Asmodeus refuses to see Mammon's reactions.

On the first day, everyone goes on the tour of the Demon Lord's Castle conducted by Little D. No. 2. The tour starts with the portrait of the current Demon King, Diavolo's father. Diavolo mentioned that he hadn't seen him in several hundred years as he is slumbering at the bottom of the Devildom. While they were passing through the stairways, Helene recognized Asmodeus and as a result of her leftover powers, Mammon, Leviathan, Beelzebub, Solomon, Asmodeus and MC was pulled into the painting, ending up in the underground labyrinth. Lucifer cotinued the tour regardless. A snake, Leviathan's Henry 1.0, rests in the labyrinth and chased after the group who fell in. Asmodues, who's power was amplified by Solomon's magic, was able charm the snake and let it show the way out. Later that night, Mammon showed up in MC's room, wanting a pillow fight. However, Lucifer overheard Mammon badmouthing him and pulled him to the room Diavolo and Lucifer shares. Simeon comments that they could sleep peacefully that night.

Lesson 8
The second day of the retreat arrives. Mammon didn't seem to get any sleep last night due to Lucifer, and the rest of the brothers had fun interpreting what Diavolo had said. Since the iternary for the day was scavenger hunt, each group will be given riddles to solve for a historical item in the castle and take a picture of it. However, with Asmodeus disrupting things, such as charming a goddess statue so that she wouldn't go back to her original pose, Luke's group is not able to complete their riddle solving. Asmodeus leaves so that he wouldn't have to heard Satan's lecturing. MC follows Asmodues. MC tries to make a pact with Asmodeus, but he said that only on the condition that they manage to outsmary Lucifer, such as getting a picture of Lucifer's sleeping face. Later, Luke serves dishes from the Celestial Realm that he made for dinner on the second day, and MC tries to get a hint of where Lucifer's room is.

In lesson 8-8, Diavolo transforms the Hall and fills it with guests from across the Devildom for the formal dance. The demons and even Diavolo transforms into their demon forms for the dance. Mammon nervously asks MC for a dance, claiming that as long as MC doesn't have a partner, he would pair with them for the dance. Satan and Leviathan teases Mammon and Lucifer appears, telling MC to dance with him immediately, shocking Mammon. As Lucifer and MC dances, he lists the reason why one might ask someone else to dance, including the reson that they want to have a private conversation. Words were exchanged before Solomon appears and invites MC to dance. Lucifer leaves, not befoe giving a final warning to MC. Solomon talks with MC and lends them some of his powers for six hours. Later that night, MC, Mammon, Leviathan and Beelzebub commences 'Operation Photograph Lucifer Sleeping'. When they entered what is supposed to be Lucifer's room, Cerberus appeared. When the four found a door to escape from, they rushed through it only to fall back into the underground labyrinth with Henry 1.0 chasing them. Using Solomon's borrowed powers, MC summons Asmodeus to tame Henry 1.0. They discover that amount of MC's magical powers was much more as compared to Solomon's. When the four returns to the castle, Lucifer explains that if someone opens his room door without knocking, it transports them straight to Cerberus's room to prevent thief of the castle's valuables. Having seen the amount of MC's magical powers, Asmodeus was impressed and decided to make a pact with MC. MC now has a pact with four demons.

Later that night, Asmodeus fusses over MC, even asking to sleep in the same bed as them. Mammon suddenly appears, kicking the door open and trying to stop Asmodeus. Satan and Leviathan appears, surprised at the sight before them. Being annoyed at Asmodeus's proximity to MC, Mammon threw a pillow in Asmodeus's face, causing a pillow fight to escalate between Mammon, Asmodues, Satan, Simeon, Luke, Solomon, Lucifer and Diavolo. After the pillow fight ended and everyone went to bed, Diavolo and Lucifer discusses MC's pact making in the garden. Lucifer sighs and asked Diavolo why he had to pick MC as the exchange student. Turns out, Satan and Barbatos have been eavesdropping on the conversation.

Lesson 9
Returning home to the House of Lamentation after three days away on a retreat, Asmodeus questions MC why they want to make a pact with all the demon brothers; MC responds with wanting to get Lucifer’s respect. Satan along with Lucifer asks what is the point of getting Lucifer’s respect and what MC is trying to accomplish. Satan states that he would also be making a pact with the purpose of making it hard on Lucifer. Satan & Lucifer get into an argument which ends with Lucifer wanting to kick Satan out of the house and MC tries to calm them down which angers Satan more and he ends up leaving.

The scene moves to MC’s bedroom along with the other brothers except Satan and Lucifer, where MC tells that the plan is to get Lucifer make up with Belphegor and why MC wants to make pacts with all of the brothers. Asmodeus states that Satan will do anything to make Lucifer upset - even making a pact with MC. But Beelzebub contradicts the idea of earning Lucifer’s respect in that way not if Satan makes a pact with a reason like that. MC asks why Satan hates Lucifer; Asmodeus answers MC by stating that the more people are alike the more they hate each other, Leviathan states it’s more of an Oedipus complex thing. Mammon explains that during that time Lucifer was really mad at their father and Satan was born from that Wrath. Beelzebub supports Mammon’s statement saying that Satan was nothing more than emotion itself, Satan was wrath. Asmodeus & Leviathan agrees saying they basically raised Satan during that time, but Satan was especially influenced by Lucifer.

MC goes to Satan’s bedroom, where Satan is trying to gather which books to take with him since he can’t take them all. Satan warns MC of one book in particular as it's a forbidden book where if two people touch it, they’ll switch bodies. Satan shares with MC that their father was the one who bestowed upon their names based on their power as demons, from most to least powerful. Therefore Satan was the last to be born into the world and the fourth most powerful, he was born from Lucifer himself which irritates him very much. MC disagrees with Satan for making a pact for the sole reason to irritate Lucifer, this angers Satan but he's abruptly stopped by Lucifer. The two begin a heated argument and MC tries to calm them down, as Satan’s wrath grows stronger the books all around the room starts to fly off the shelves and shooting towards Lucifer. Lucifer grabs one of the books and recognizes it's the forbidden book Satan has warned MC about before. A flash of white appears and the two brothers Satan and Lucifer has switched bodies. Satan (now in Lucifer's body) imitates Lucifer jokingly and states that the effect of the body switch lasts for several days. Lucifer (now in Satan's body) still suggests they go to school even if they have switched bodies for he does not want Diavolo asking questions. Lucifer insists to keep an eye on Satan so he doesn’t get into any trouble while he is in his body. Lucifer implies that they must stay in one’s particular room Satan is appalled by the idea. The other four offers and suggests their rooms but in the Lucifer decides it’s best if they both stay in MC’s room.

In MC’s room, Lucifer discusses on how things would work now that they have switched bodies. He declares two fundamental rules they must abide to: First, neither him or Satan is allowed to go into each other’s rooms unless the other is present as well. Second, they would be avoid doing anything that might attract attention while at school. Mammon feels relieved that even though Lucifer is scolding him he doesn’t feel inferior nor scared of his nagging. The next day at school, Lucifer opens up to MC saying he doesn’t trust the two knowing Satan and Mammon will try to make the whole situation funny, he then wants MC to keep an eye on the two. Diavolo appears and greets Satan, he asks what has happened to him today for he was always at the assembly hall first thing in the morning. Satan mocks the impression of Lucifer in front of Diavolo which made him realize that him and Lucifer had their bodies switched. Diavolo reminds Lucifer that he has been scheduled to give a speech to the entire student body the day after tomorrow, the speech is a report to the full student body on the current state of the exchange program and how all of their exchange students are doing. Lucifer concludes that if they haven’t switched back to normal then Satan would have to deliver the speech as himself. MC suggests to talk things out with Satan they later find Satan in MC’s room.

Satan continues to mock Lucifer by making impressions and saying things Lucifer normally wouldn’t say even inviting Leviathan and Beelzebub to harass Lucifer. Mammon plans to take advantage of the fact that with their bodies switched they could infiltrate partying with the other demons & accepting bribe from the RAD newspaper club. The fight between Satan and Lucifer gets worse in MC’s room. MC can’t fall asleep so they go out the hall where they hear a voice. MC finds Mammon hanged right-side up by Beelzebub ordered by Lucifer. MC helps Mammon break free but on one condition if he agrees to convince Satan and Lucifer to make up the they’ll let him down. Mammon agrees with MC’s condition and has had an amazing idea on how the two would make-up.

Lesson 10
In Leviathan’s room, Mammon presents to MC a game named Doji⭐️Maji⭐️Memorium (Dogi Maji for short). Anyone who registers to play is actually pulled into the game world for real. Mammon plans to have Satan and Lucifer work together toward a common goal while playing the game. Lucifer, Mammon, Leviathan, Satan, and MC enters the game.

Inside the game, MC and the others are transferred in school Leviathan explains that Dogi Maji is a school dating sim; one character is designated as the heroine and the others have to work hard to increase your favorability score with her higher and higher, in the end the player must go up the Roof of Legend and profess their love for the heroine, and if she accepts them, they win. MC is the designated heroine, Lucifer is no longer in Satan’s body in the game as well as Satan in Lucifer’s body. Satan challenges Lucifer on who would get to raise intimacy with MC first but the other two refuses to be beaten.

In the classroom, MC interacts with Mammon, which affects his intimacy level. On the hallway, MC bumps into Satan and helps with the stuff they are carrying to the classroom also affecting his intimacy level. On the school grounds, Leviathan makes MC a homemade Ruri-chan themed three-layered bento box lunch which. MC heads up to the roof to find Lucifer, where he's laying on a bench taking a nap. Lucifer skips class because there is no Diavolo in this world so he could do whatever he wants without worrying about being a disgrace to him in any way. MC's reply also affects his intimacy here.

(Lesson 10-A) Back in the House of Lamentation, Asmodeus is looking for MC along with Beelzebub. They head towards Satan’s room but only find it in a chaotic state. As the two are cleaning up Satan’s room of books they happen to touch the forbidden book that made Satan and Lucifer switch bodies. Beelzebub and Asmodeus has also switched bodies. (Lesson 10-C) The two brothers become curios about each others bodies, Asmodeus (in Beelzebub's body) persists taking Beelzebub’s clothes off wondering how he has pecs even though he eats a lot; Beelzebub (in Asmodeus's body) on the other hand is wondering why is Asmodeus’s body very soft. Suddenly the two feel hungry and they come to understand what it means to be in each other’s shoes. In a flash, both return to their respective bodies. The forbidden book looks more worn out than usual, Asmodeus states that the more they use it to switch bodies the more worn out it becomes until it eventually can’t be used anymore.

Back in Dogi Maji, it is the final day where the players must profess their love to the MC. Lucifer begins to be nice to MC for the sole purpose of ending the game immediately. Satan confronts MC in the school hallway and apologizes about Lucifer and for getting MC caught up in a weird business. MC tells him to wait and that he doesn’t have to force himself to like someone he doesn’t. MC also tells him that Lucifer doesn’t see Satan as a child as much as he thinks and he only wants to look good in front of Diavolo as his right hand man. Satan is convinced and thanks MC for the refreshing point of view of the situation is and was the first person to tell him this.

On the rooftop, monsters start popping out of nowhere over the school and has changed the game into a ultra-hard survival fight. The monsters start to devour computer-controlled classmates and the five are barely able to survive. Leviathan seems to be excited of the crazy plot twist in a simple dating sim, not to mention how bloody the game was. Satan gives an idea to the group that they are likely meant to have survived and seems to have hit the final battle. The last boss appears to be Cerberus, but Satan suggests that it is not the same Cerberus as the one they have in the Devildom. Lucifer commands Cerberus to sit which angers the demon dog more. Cerberus charges toward Satan and is about to strike, Lucifer halts and commands Cerberus to sit once more and threatens the dog if he does anything to harm his brother. Cerberus whimpers and is calmed down. The screen is filled with confetti stating that the Mission is Complete. Back in Leviathan’s room, Satan and Lucifer remains to have their bodies switched in the real world. Leviathan suggests that the two might be better off inside the game for the time being, Mammon warns them about Cerberus but Satan disagrees for he has Lucifer beside him. The two brothers seems to have an agreement with each other and gradually accepts one another. Leviathan later reviews Doji Maji online in Akuzon.

Lesson 11
Somewhere in the Devildom, Lucifer, who’s still in Satan’s body, MC, and Mammon walk together and speak about Satan. Then, Lucifer takes them to a restaurant. After eating, it’s revealed he did it so that the two others will compensate him and go to the human world to help him find the witch who created the curse of the body switch in order to lift it; Mammon is pretty reluctant about going there because he’s afraid of witches. However, only certain demons can travel to the human world directly and since Lucifer is in Satan’s body, the magic doesn’t recognize him and they can’t travel. Satan suddenly arrives and decides to help them since he's in Lucifer's body, which means the eternal magic seal will let him pass. Thus, they travel together.

Once in the human world, Mammon’s attitude changes completely and he enjoys himself. At Victoria Station, Lucifer buys four matching keychains for the entire group, which is pretty surprising that he spends money for them, especially when it was Mammon’s wish. Next, they’re in a private cabin inside a train. Mammon leaves them to find the dining car so he can take a picture of the food and brag to Beelzebub. However, he stumbles in to the wrong room and gets accused of a woman's murder. Lucifer, Satan, and MC arrive at the scene after hearing her last scream and a description of a person that fits Mammon.

They meet Lucas, Sophia, Noah, and the dead woman, who appears to be Grisella, the witch the group was especially searching for. Lucifer uses his powers to hypnotize the three humans so that they go away. Back in their own car, they hear the ghost of Grisella, who wants them to solve her murder in exchange for lifting the curse of the body switch. All the demons decide to torture the three suspects, but MC wants to find another way less violent; “the human way”. They question Grisella and Mammon, and with the information the demon brother had said, they guess who’s the killer. As the three humans gather, the witch warns MC about Lucifer, saying he’ll soon lose the trust he puts in them.

Once in front of the suspects, Satan decides to explain MC’s thoughts and claims the killer is Noah. It turns out to be right, as he says he truly wanted to become Grisella’s apprentice but the witch didn’t want to take one because she predicted she’d die in the train, which broke the man’s heart; ironically, it’s exactly why she was killed. Back in their car, Grisella lifts the curse of the body switch. Surprisingly, Lucifer asks Satan to do the speech about the report he’s supposed to do tomorrow, and his brother agrees with confidence.

Lesson 12
Lucifer proposes a toast with everyone (Leviathan is absent) along with Diavolo for lifting the curse that had Lucifer and Satan in each other’s bodies, Lucifer then congratulates Satan on delivering the speech to the entire student body. Lucifer and Satan both jokingly impersonates each other confusing the others and everyone seems to be in a good mood tonight, and they’re all enjoying themselves. Diavolo thanks the MC for among other things seeing how happy Lucifer seems to be. MC asks Diavolo on how they were chosen to be an exchange student in the first place, he later explains that it wasn’t him that chose them but Lucifer.

(Lesson 12-A) A conversation between Diavolo, Barbatos, and Lucifer are taking place. Lucifer denies he had an exciting adventure by switching bodies with Satan, surviving a video game, and even visiting the human world. Diavolo and Barbatos point out they are jealous of how Lucifer enjoyed himself in the human world and he clearly doesn't deny that it was fun. Diavolo also asks if Lucifer bought any souvenirs with him since he has a decorative strap attached to his D.D.D. Barbatos recognizes it as Harrison Porter chocolate lizard keychain which can only be bought in a shop in London Victoria Station. He also mentions that Mammon, Satan, and MC has the same keychain as well.

(Lesson 12-C) Diavolo suggests they come to the human world as well along with Lucifer, he mentions a witch named Artemesia and how they should perhaps give her a visit. Lucifer refuses for they owe the witch a great amount for Mammon’s sake. Diavolo mentions MC and notices how well they are getting along with Lucifer and his brothers. Lucifer admits that Diavolo’s plan may be working and his brothers are starting to see humans in a new light now and it’s due to MC’s influence, he also admits he trusts MC now. Diavolo then proposes on celebrating along with the others at Ristorante Six. After Lucifer leaves, Diavolo seems worried about Lucifer and Barbatos suspects that what’s about to happen will wound him deeply.

At Ristorante Six, MC is having a conversation with Diavolo. He shares that he believes everyone has a mission in life. His is to bring progress and stability to the Devildom, the Celestial Realm, and the human world. Something happened once and that made him firmly believe in this. It’s possible that MC’s mission in life is to influence Lucifer and his brothers in some way. He hopes that whatever influence MC does end up having it turns out beneficial to them.

Outside of the Devildom, MC walks alongside Lucifer as Mammon, Asmodeus and Beelzebub went to go ahead first. Lucifer asks MC what conversation happened between Diavolo and themself. Lucifer also states that there was no particular reason why he ended up choosing MC for there was suddenly a breeze that blew through the window scattering the lists into the air and one of them happened to land at his feet with MC’s name on it. He also says there was nothing special with MC being chosen as an exchange student but MC is somewhat special to him on a personal level. Lucifer’s phone starts ringing and it turns out to be a call from Leviathan; back at Leviathan’s room, he seems to be skeptical for they aren’t picking up their D.D.D. Leviathan then screams and disappears.

At the House of Lamentation Lucifer is trying to find Leviathan in his room, only finding his D.D.D laying on the ground and Leviathan himself is nowhere to be seen. Lucifer then notices that Beelzebub is also missing. In front of the House Of Lamentation, Asmodeus complains that searching for the two at this late hour is bad for his skin. Lucifer suggests that they split up, having Satan and MC to search for the two.

Lucifer then recalls the story about the House of Lamentation; It was long ago, back before the place was even called the House of Lamentation. The house was built on the outskirts of a village in the human world, at the same time a married couple and their seven children lived there along with one servant. They appeared to be a happy, well-off family that enjoyed living out the country. However, one day the oldest son came running into the village constable’s office looking pale. He delivered a horrifying piece of news that their servant has murdered everyone in his family and then took his own life. The constable’s men went back with him and were greeted with a ghastly sight. Every person in the family had been murdered, each in a different way and in a different location. The servant was found in his room hanging a rope around his neck. The constable concluded the servant must have reasons that plotted to kill his masters and take his own life, and since the perpetrator was dead they decided that the case was closed. However, sometime later several facts came to light that gave rise to new doubts. The only person who wasn’t killed was the oldest son who had been on extremely bad terms with his siblings. He had also purchased a gun just like the one used in the murders shortly before they occurred. A postman was also a witness seeing the servant argue with the oldest son prior to the killings which led people to think that maybe the oldest son was the true killer. In the end, the truth never came to light. The oldest son lived in the house by himself and eventually died of old age. At some point, the house was given a name “The House of Lamentation”.

Later, Satan asks MC to make a pact with him. MC is surprised and asks the reason why he suddenly wants to make a pact with them. Satan clears it up by stating that he is not doing this to make Lucifer angry. Satan decides that he won’t let what Lucifer does bother him anymore and is reminded by what Grisella said that you have to accept the hand fate deals you no matter what. What matters is how you handle it. Satan was able to face his issues because of MC, as they were the one who helped him be honest with Lucifer along with himself. Now MC has successfully made the 5th pact with Satan. Later on, the three hear screams that sound like Mammon and Asmodeus to Satan. In the portrait room Satan feels uneasy that the other brothers are disappearing. Then he suddenly disappears as well, leaving Lucifer and MC alone.

Lucifer suggests MC to go back to Leviathan’s room for he was the first to disappear. On the way back they hold hands and notice Leviathan’s PC monitor is still turned on. Lucifer recalls Levi ordering a new game from Akuzon and found the game The Demon House which sounds like a horror game that describes the situation they are in right now. Lucifer suggests MC that they complete the game and see what happens, upon searching the internet it states that in order to complete the game, you must defeat the demon that serves the final boss and the boss’s name is Lucifer as well.

In the library of the House of Lamentation, MC is with Lucifer he states that with everyone gone the MC must defeat him since he is the final boss, and to end the ridiculous game, it is either that or they fall in love with each other. Lucifer decides that he would not bother to lose face in front of Diavolo by being defeated so the only choice MC has is to fall in love with each other. Lucifer suggests if between MC and him do they really need his other brothers, so they stat by trying the fundamentals of love and go from there and it starts by getting to know each other well. Lucifer proceeds to ask MC questions; as the questions proceed MC asks Lucifer what he thinks of humans but he depicts the question as to what does he think of MC. He then explains that MC had his thoughts all he has to do was make sure they survived a year without any incidents being careful and to ensure that MC did not get into any trouble by being eaten by a random demon somewhere but in the end, MC managed to make pacts with his brothers one by one. Lucifer asks MC why’d they make pacts with them, he recognizes MC's worth but confronts them about what exactly they're trying to achieve in the long term. MC finally tells Lucifer they met with Belphegor and this enrages him.

Mammon appears along with Asmodeus, Leviathan, Beelzebub, and Satan. Beelzebub finally hears about Belphegor not being in the human world and is actually locked in the attic this enrages Beelzebub. Lucifer ends up hurting Beelzebub, and Belphegor suddenly appears along with them.

Lesson 13
As Belphegor shows up unexpectedly, everyone is shocked and confused. Belphie confronts Lucifer and Beel is still very angry, though he is grateful to MC since they helped his twin. Things escalated as Lucifer isn't happy about the situation and Beelzebub is feed up. In the end, Beel leaves the House of Lamentation with Belphegor and MC, leaving the remaining brothers surprised by his actions and everything else. (13-2&4)

After leaving, Belphegor laughed happily at the look in Lucifer's face, and then asked Beel if it was really okay to leave like that. He answered that he didn't know, but they couldn't go back anymore. He then proceeds to apologize for dragging MC, explaining that he thought it would be dangerous to leave them with Lucifer. MC is grateful. Beel then explains that the brothers went missing as a prank, suggested by Satan, in order to make Lucifer and MC get along and etc. MC then asks what they are gonna do now, and Beel says he is hungry, which makes Belphie nostalgic. As they were smelling BLT devil sandwiches, Simeon shows up, surprised by seeing Belphie. They talk and Simeon allows them to stay in the Purgatory Hall. (13-7)

Lesson 14
14-1 MC and Beel return back to the House of Lamentation with intentions to talk to Lucifer (About Belphie), but firstly MC will need the help of all of the brothers and has to goes to apologize to all the brothers, starting with Mammon (in this lesson), who, after accepting MC's apology, offers to help MC get to Lucifer (Who locked himself up in his room).

14-A Back in the Purgatory Hall, Luke is extremely worried about MC and Beel, while Simeon and Solomon try to calm him down (although Solomon is more teasing than helping). Simeon successfully distracts Luke with baking, only to find Solomon deep in the thought. Solomon wonders why is Lucifer loyal to Diavolo.

14-C Solomon questions is Simeon knows something that he doesn't about Lucifer's loyalty to Diavolo, to which Simeon answers that to him Diavolo and Lucifer seem as close friends rater than a master and loyal servant or that at least Diavolo sees Lucifer like that. In the flashback we see Simeon visiting the Devildom for the first time after Lucifer's rebellion and Diavolo being extremely friendly with Lucifer (to the point Lucifer had to stop him from embarrassing him any further. Solomon's and Simeon's conversation is interrupted by Luke yelling about his burnt cookies.

14-4 Next, the two of them visit Levi, who is talking with Henry (the fish) about how betraying and awful humans are, ignoring MC's and Mammon's presence in his room (Even though Mammon kicked down his door). He continues to rant to Henry about his lost friendship, about feeling used and manipulated, all until Mammon calls him and otaku (derogatory), where Levi snaps out just to tell Mammon not to use that word as an insult, that he is a moron and that MC's a backstabbing human and that he wishes for them both to die. Mammon comments how "Levi reverted back to his old sad and gloomy shut-in of an otaku (derogatory) self", causing Levi to snap again and say that Mammon can stop repeating his words, that he knows that he is "a sad, gloomy, annoying, useless, socially awkward, gross, recluse shut-in of an otaku", making Mammon feel slightly bad. Mammon tries to explain to Levi that MC's pacts with him didn't have anything to do with Belphie, which doesn't make Levi more trusting towards MC, just more convinced that Mammon lacks brain cells. MC then can either apologize or ask for Levi's trust, both leading to nothing, but then MC uses a TSL reference (Regarding the friendship between the Lord of Shadow and the great hero Henry) and Levi switches almost instantly (Mammon makes a comment that the magic words to Levi's heart are "True Friend" and "TSL"), jumping to hug MC (Making Mammon jealous) and calling them his true friend. He then joins the duo in their plan of luring Lucifer out of his room, even if he knows he won't like it.

14-6 The group is then joined by Satan, Asmo and Beel, who state that Mammon's plan (and Mammon) is terribly stupid but are still going with it because it's their only plan, resulting in small bickering between the brothers. They have all gathered by the Grimoire, in the underground tomb, which MC is supposed to use to get Lucifer out of his room, but Cerberus is patrolling the place, which is why they have to sneak and be quiet (They didn't do that well). After MC suggests to move the book to the safer place, the brothers explain that it would lose it's meaning and that she (Meaning Lilith) would get lonely.

14-10 MC finds out that the (empty) coffin on which the Grimoire rests is for Lilith after they ask about it. Mammon rushes MC to take the book after everyone's mood goes down, which MC goes for and Mammon reassures them that he will protect them when Lucifer rushes downstairs to kill them. Then, Cerberus appears and Mammon once again rushes the MC to pick it up, when MC touches it we see a flashback from when Lucifer fell and made a deal with Diavolo to be by his side forever in exchange for Lilith's life.

14-12 The flashback ends with Mammon once again yelling at MC to pick up the Grimoire, but the book is covered in ivy that is not letting the book go and Satan yells that he can't hold Cerberus back anymore. At that point, Lucifer finally appears and orders the dog to sit. Lucifer notices Beel and MC and the chapter ends.

14-15 As a first option MC gets to hug Lucifer or hit him (would not recommend). If MC chooses to hug him everyone is taken back a bit (and Mammon and Levi obviously jealous). Lucifer is slightly confused if this is supposed to be an apology and Asmo suggests it could be love, making Lucifer blush and order MC to get off of him instantly. MC then asks to talk to Lucifer to which everyone, including Lucifer agrees after others push him into it. But once everyone is back upstairs, nobody is willing to start talking until MC speaks first. Levi tells them that they are needed here for this conversation because they are like family now. On the mention of that word, Beel brings out the topic of Belphie. Lucifer states that yes, Belphie is family and that that's why he locked him away

14-17 Beel is not happy about that answer and is very close to snapping again, but his brothers and MC calm him down, as this is not going to help anyone. Satan then gives the word to MC as they came back to this house to ask Lucifer something and MC requests to know the truth about how all of this happened. Lucifer starts explaining the whole situation from Diavolo's plan to Belphegor openly being against humans as a race in total. not just the exchange student program.

14-19 Lucifer then proceeds to explain that the reason he locked Belphie up is not just because he was against Diavolo's idea. The reason was (as seen is a flashback) that Belphie said he will destroy the whole human race (He accuses all the humans for what happened to Lilith) and then proceeds to commit treason against Diavolo (Saying he will kill him) and then says he will kill Lucifer too if he tries to stop him. He turns into his demon form and attacks Lucifer, who easily stops him and locks Belphie up for his own safety.

Lesson 15
The brothers explain to MC why Belphegor hates humans. They talked about the time when they were still angels, when Lilith was still alive, and when Belphegor loved humans (15-2). The first four parts of the lesson revolves around the story of how the brothers got banished to the Devildom, the death of Lilith, the reason of Lucifer's loyalty to Diavolo, and Lilith's rebirth as a human.

Upon knowing the story, MC and the brothers decided to pay Diavolo a visit. They ask Diavolo to release Belphegor. Diavolo agrees but under the condition that MC completes a task — to travel back into the past and ascertain exactly who it was that released Belphegor. And so, into the past, MC goes...

MC returns to the time when the brothers are disappearing one-by-one. They learn that the brothers did not 'vanish', the act is part of their plan to get Lucifer and MC to make up. The brothers believe that they have been caught red-handed and urges MC to go back to the room and patch things up with Lucifer. So MC did, without telling the brothers about the time-traveling situation. They arrive outside the room and hears Lucifer complaining about how ridiculous the game is. Just as the pair begin to exit the room...

Lesson 16
MC hides in the secret room, a replica of Lilith's bedroom, to avoid being seen by their other-self. They're hit by Lilith's memories upon entering the room. With the memory in mind, MC heads to the attic. They touch the door to Belphegor's attic room which magically opens. They enter the room to find Belphegor sleeping.

Belphegor wakes up and realizes that he is now free and overwhelms MC with his appreciation. After all, it is finally time for him to achieve what he set out to do (16-6). He turns into his demon form and begins to ridicule humans. He laughs at MC for falling into his trap and attacks them.

Unable to withstand the pain, MC faints. They meet Lilith in a dream-like world. They learn that Lilith remembered everything after her death as a human and has been watching over her brothers ever since then. She tells MC that they are her ... which is why she will lend her power so MC can save her brothers (16-10).

MC wakes up and discovers that they are not injured despite being attacked by Belphegor. They hear arguments downstairs and heads to the source. They see an injured MC dying in Mammon's arms. MC reveals themselves to take a better look at the situation. The next second, the MC in Mammon's arm disappears. The brothers are very confused. Belphegor, determined to kill MC, begins his second attack only to be stopped by the story of Lilith (16-12).

While Lucifer is asking where MC heard the story from, Diavolo enters the scene and reveals that MC is a distant descendant of the human Lilith. He asks MC if they ever had visions of Lilith's memories. MC recalls the moment when Lucifer pledges his loyalty and allegiance to Diavolo in exchange for Lilith's life (16-15).

The brothers convince Belphegor that Lilith lived a happy life as a human and that he's supposed to be happy about it. Belphegor spills his thoughts, blaming himself for Lilith's death, and Lucifer says that he should've told them earlier. After both confessions, they host a celebration. Belphegor immediately hogs MC. When asked about the other MC's disappearance, Barbatos reveals another secret about his power — the power to select from any number of different potential realities and make any of them into the sole reality. With all questions answered, the chapter ends with the brothers fighting for MC's attention.

Lesson 17
The brothers are having breakfast and Beelzebub eats Leviathan's meal. When Belphegor enters, things get awkward and the brothers start to act cautious. Leviathan announces that he's going to grab his food in the cafeteria. Beelzebub, Satan, Mammon and Asmodeus come along. Asmodeus questions MC whether they are coming along too. MC could agree or say that they would come along with Belphegor. Belphegor responds saying that there is no need to wait from him. MC could either insist to come with Belphegor or decide to leave. Lucifer then comes in and announce Diavolo's birthday party. (17-2)

Unfortunately, Belphegor notices his brothers’ wariness of him. Simeon suggests MC to "serve as a bridge" for the brothers. MC goes to the planetarium with Belphegor asking them of what they were planning on giving Diavolo for his birthday present until they were interrupted by a loud noise coming from the music room. They both go to find the source of the noise. (17-4 and 17-7)

They catch Mammon rummaging through the music room. Belphegor proceeds to interrogate him while accusing him of stealing. Mammon retorts that it is because he wants to give someone a present. Belphegor asks him whether the present was for Diavolo or not. Mammon questions why would he give a present to Diavolo. Belphegor complies saying his birthday was in near future. Mammon was dazed but then he confirms it was for Diavolo. Belphegor changes the topic of getting money for Diavolo’s present, he suggests working a job in Hell’s Kitchen, where they work acting as chefs and waiters. Belphegor quickly gives the orders to a confused Mammon. Mammon asks MC about the orders. (17-10)

Someone calls MC’s name which turned out to be Leviathan. He called us and started acting suspicious and wary, he says that Belphegor invites him to game with him, he worries that it would be awkward and he also notes on how he had a package to accept from Akuzon, which is why he asks MC a favor, to send Belphegor the message. MC proceeds to tell Belphegor the message until Leviathan comes in. MC could offer words of encouragement to Belphegor or defend Leviathan. Belphegor tells him that he got his message. Leviathan continues saying that he can now game with him. MC joins to game. Belphegor sleeps in the middle of gaming resulting him as last. Leviathan seemed surprised and slightly disappointed but then noted how he shouldn’t have been worried at all happily. (17-12 and 17-14)

MC and Belphegor are playing cards. Belphegor loses each one yet he insists with playing another round. Satan interrupts, noting how Belphegor would just lose again to MC. However, they continue playing the cards. MC could ask Satan to cheer on Belphegor or themselves. Lucifer enters, requesting Satan to talk with him about Diavolo’s birthday. Satan agrees but asks to discuss this elsewhere with him. Belphegor notes how Satan was acting oddly, he says that Satan wasn’t as agreeable with Lucifer as seen before. Belphegor questions MC whether they know anything about it. MC could either taunt and tease him before telling him the story or directly tell him the story. MC proceeds to tell him the story of how Satan and Lucifer’s relationship changed. (17-17)

After MC told him the story of how Satan and Lucifer’s relationship changed, Belphegor was very disappointed that he didn’t see it all unravel. He also noted on how surprised he was. Satan overheard them and comments on how he still loved to see Lucifer suffer. Belphegor then suggested one of the ideas he came up with when he was in the attic, “The Formerly Anti-Lucifer League” He mentioned how their goal was to make Lucifer’s life as hard as possible. MC, Belphegor, and Satan then proceed to go to library where there is an enchantment is casted on a secret door that contains Lucifer’s prized Demonus. They all assume that there is a secret code or phrase to lift the enchantment and started making taunting phrases to get the door open. Unfortunately, they are caught by Lucifer. MC could apologize or lie that they were just passing by. (17-20)

Lesson 18
MC and Belphegor are shopping for Diavolo's birthday present. Belphegor suggests a gag gift as they go out shopping when Solomon interrupts. Solomon mentions that he also ran into Asmodeus along the way. He questions MC and Belphegor on what they were doing. Solomon continues questioning, asking whether Belphegor was planning on making a pact with MC. He also exclaims that he himself would like to make a pact with Belphegor. It is noted by Solomon that Belphegor glanced at MC’s direction, checking for a reaction. Belphegor and MC leaves Solomon to continue. (18-1)

Belphegor and MC arrive back to the House of Lamentation after shopping. They were about to go back to their perspective rooms when Asmodeus comes along and drag them both to his room. He invites them in as he mentions that he cannot reach a decision. He asks MC to help, by asking them what sort of outfit do they like. MC could either pick a mature, subdued sort of look or something cute and girly. It is found out that the outfit was for MC. Belphegor then asks if they were done picking the outfit and drags MC out of the room. (18-4)

MC, Leviathan, and Mammon are seen to be playing a videogame (Rags to Riches: The Paradise and Underworld Life Simulation Game) in MC’s room until Belphegor interrupts after an apparent fight with Beelzebub. Mammon looks surprised as Belphegor tells all of them that it was because Beelzebub was feeling guilty because he didn’t know Belphegor was being held prisoner and then they had a fight as he walked out on Beelzebub. Belphegor requests MC to sleep in their room as Mammon aggressively declines. He raises the idea of making Belphegor and Beelzebub to make up and asks MC to help him. (18-6)

When MC and Mammon went to search for Beelzebub, he wasn’t in his room. They find him in the kitchen cooking soup for Belphegor. Mammon tells Beelzebub that Belphegor was in MC’s room as they take the soup over to him. Beelzebub worries whether or not Belphegor would forgive him. MC could either say that Beelzebub worries too much or that his thoughts are rude to Belphegor. Leviathan and Belphegor himself comes out of MC’s room, saying that everyone was being too loud. Belphegor was very tired of Beelzebub’s behaviour so far and slaps him in spite of that. Belphegor said firmly that it was none of Beelzebub’s fault. He cuts some slack to him as the two make up. (18-10)

MC is seen to be in class when Lucifer invites them to go out shopping with him for Diavolo’s present. After shopping, MC and Lucifer are seen to be having dinner at Ristorante Six. Lucifer thanks MC for going out shopping with him and raises the topic of MC helping Belphegor and his brothers patch things up and thanks MC for it. He also mentions that they are lucky and that he is glad that MC came to the Devildom. MC could say that they are glad too or that they can’t wait to go back to the Human World. After dinner, Lucifer invites MC to ‘hang out’ a bit more. (18-12)

It is found out that Lucifer leads MC to the planetarium where they find Belphegor. Lucifer invites MC and Belphegor to come with him for an opinion. It is found out that he led them to Lilith’s room up from the Celestial Realm. He confesses that he created the room and that he vowed to never forget Lilith but the secret that he has been keeping from all of them -the secret of Lilith being reborn as a human- was too much too bear so he unloaded it all onto Lilith’s room and left it. He admitted that he didn’t need the room anymore, because he had everyone else. Belphegor stated that he still misses Lilith. Lucifer is well aware of that, which is why he wants Belphegor to use Lilith’s room if he needs it. Belphegor stays quiet for a few moments and made a decision. He says that he also didn’t need the room, that he is still very sad that Lilith’s gone but having the room wouldn’t change anything. He wants to move onward. He thanks Lucifer for being able to make the decision as the two make up. (18-15)

Everyone is seen in the Demon Lord’s Castle as Diavolo’s party is beginning. Diavolo gives a speech and it is found out that this party was meant for MC too as the guest of honour. The brothers give MC their gifts but Belphegor is nowhere to be seen. MC goes to look for him. (18-17)Belphegor is found in the garden. He claims it’s because parties weren’t his thing. He asks MC whether they should really be outside at the moment since they are the guest of honour. He also knows that his brothers have probably given their gifts and notices that MC seemed really happy with their gifts. He admits he wasn’t sure what to give MC so he decides to give himself. Make a pact with MC. MC has done their 6th pact with Belphegor. Asmodeus, Beelzebub, and Mammon found both of them and urges them to go back as MC’s the guest of honour. Belphegor holds out his hand to MC. MC can choose whether to take his hand or not. (18-19)

All of the brothers are seen in Lucifer’s private study called by Lucifer himself, where he announces his idea of making this year’s event Diavolo’s birthday party and a welcome party for MC. Belphegor is shown to be surprised that the others have never raised a welcome party for MC. Everyone is shown to agree with the idea except Mammon. Asmodeus decides to buy a present for MC, so the others do the same. Belphegor raises the idea that he should give MC himself, as to offer being in a pact with them. All of the brothers are seen to be asking MC what they desire more than anything all over the part. At the end, MC and Belphegor are seen to be at a street in Devildom. Belphegor notes on how everyone keeps asking MC about their desire. MC could respond saying why does he think everyone’s asking so or is he going to ask them about what they want. (18-A and 18-C)

Beelzebub and Satan are seen to be playing chess in the music room of the House of Lamentation with MC and Belphegor. Lucifer then enters, searching for Belphegor. Lucifer then tells him about the missed classes of RAD and about how he has to make up for that time and learn all about the materials he missed. Lucifer also tells Belphegor that he was going to be given a special exam. Lucifer then gives Belphegor all of his assignments as Belphegor complains. Lucifer also tells Beelzebub and Satan not to help him. (18-15 Hard)

MC and Belphegor are seen in Beelzebub and Belphegor’s room with Belphegor studying. MC is seen helping Belphegor studying. Belphegor will ask MC on questions about human history. If MC answers all of them correctly, the intimacy level will be raised. Mammon then enters the room and tries to take the opportunity to offer help to him in exchange for money. Belphegor rudely declines the offer. Then Asmodeus enters the room to watch Belphegor study. Satan also comes in to offer Belphegor a study reference book he used himself (An Illustrated Reference Guide to the Different Seed Varieties of the Three Worlds), which Belphegor doesn’t even study. Beelzebub enters the room, offering Belphegor a Gigadeath Burger Value Meal, gargantuan-sized. Leviathan then lastly appears, offering Belphegor to game with him to put him in a better mood. Belphegor then snaps and drags MC with him to his attic room, where he thinks is the least likely place, they will look for him. He thought that he could now focus on his schoolwork but then falls asleep on MC’s shoulder. (18-17 Hard)

Lesson 19
The brothers are having breakfast, and as Beelzebub eats Leviathan's meal again, everything in the Devildom seems to be back to normal. Belphegor enters as the room goes silent for a moment. Mammon notes that Belphegor wakes up even later than Leviathan. Asmodeus then offers to feed MC. MC could either oblige or decline. Lucifer then enters the room and tells MC about a meeting that he is going to attend discussing about the event that’s going about next week concerning MC and that he would like MC to join him. It is found out that next week marks the end of MC’s stay as an exchange student. The room is filled with silence as all of the brothers are upset about this fact. Mammon runs out of the room, joined by Leviathan. (19-2)

MC, Satan, Asmodeus, Beelzebub is seen in the living room. Lucifer requests MC to stay behind. Lucifer tells MC that the others are all sad with the fact that MC’s leaving so he wants MC to be around his brothers as much as they could in their last days. MC could respond agreeing or question Lucifer whether he, himself, wants to spend time with them. Mammon invites MC to hang out when Leviathan interrupts, demanding for his money from Mammon back. Mammon decides to run to escape Leviathan with MC. MC could either choose to ask Mammon to wait up for them or tell him to go the other way. (19-4)

Mammon worries that Leviathan will find them both soon enough. MC could either suggest to hide in Mammon’s room or Leviathan’s room. If MC decides to pick to go to Mammon’s room, Leviathan will knock on the door, the they’ll hide in the trunk of Mammon’s car (Demonio 666 Lexura). If MC decides to pick to go to Leviathan’s room. In Leviathan's room, MC could choose to tell Mammon to hide or MC could suggest to do some gaming. Either way, MC and Mammon goes to hide in Leviathan's bed (Which is the bathtub). Leviathan enters the room, badmouthing Mammon. He also admits that he finds it unfair that Mammon took MC with him. He expresses to Henry that he is very sad that MC is leaving next week. Then Leviathan leaves the room. Then MC and Mammon leaves the room. (19-7)

MC and Mammon runs out of the House of Lamentation to a night view of Devildom as Leviathan watches from afar. Mammon laughed at the look Leviathan had on his face. He confesses that he always had fun with MC around. He questions MC about staying in the Devildom the interrupted by Leviathan and Mammon runs away. Leviathan then gets tired of chasing him and admits that he too, also wants MC to stay in Devildom. (19-10)

MC is seen to be in the Student Council Room after the meeting discussing the formalities of MC going back to the Human World. Diavolo states that Lucifer seemed distraught over MC going back to the Human World. He also states that he is sad about the fact that MC is going back to the Human World. MC goes to the garden at RAD as Asmodeus spots them and invites them to hang out. MC could choose to respond saying that it sounds great or say that if they absolutely have to go with Asmodeus. (19-12)

It is found out that Asmodeus has invited MC to Hell’s Kitchen. He talks about how he puts himself over others until MC came. He continues saying that it’s nice to have MC all to himself. He wants to be the best so he decides to challenge MC to a drinking contest. MC wins the drinking contest as a drunk Asmodeus confesses that he really doesn’t want MC to go back to the human world. He starts begging MC to stay as he hugs them with tears in his eyes. Satan then finds them and carries Asmodeus back to the House of Lamentation. (19-14 and 19-17)

Satan puts Asmodeus to bed and goes back to his room where MC was waiting. Satan asks MC about a book he got from the human world. As the story goes, there was once a country that had been struck in a long war with a neighbouring land. Just as their resources were about to be exhausted, a beast with magical powers appears before their king. The beast tells the king, “I’ll help you win this war against your neighbours, but in return, you must give me that which you hold most dear.” The king agrees to these terms, and with the help of the beast’s magic, he succeeds in winning the war. But afterwards, he breaks his promise and kills the beast. The slain beast then turns into a terrible monster and curses the king’s entire country, inflicting a series of calamities upon it. Fearing the wrath of the beast, the king eventually offers his new-born daughter to it as sacrifice. At that point the disasters cease, and the land is spared. Twenty years later, the girl who was supposed to be sacrificed on the monster appears on the mountain that it lives. When the people saw the girl, they once thought dead appear before them, they’re so afraid that they try to kill her. They shoot a great valley of arrows, which hurtle down toward her like raindrops from the sky. But just as they were about to hit, the monster shields her, giving up his own life instead. Satan asks what does MC think the beast felt in its dying moments. MC could choose anger, sadness and love. MC and Satan go out of his room. Satan confesses that he knows just because MC will go to the Human World doesn’t mean that they will never meet again but he admits that the thought of MC not being around anymore makes him sad. MC then goes back to their room. (19-20)

Lesson 20
MC is in a classroom of RAD with Simeon, Luke, and Solomon chatting about going back to the human world and the Celestial Realm. MC’s back at the House of Lamentation. MC finds Beelzebub as he’s searching for someone who has gone missing, MC can choose to ask what’s wrong or stay silent. Beelzebub says that Belphegor is missing. He suggests the idea of Belphegor being upset about MC leaving that he runs away. MC helps Beelzebub in finding Belphegor. (20-2)

Belphegor is still missing as Beelzebub asks MC whether or not this phenomenon seems familiar to them. MC could answer that they both were looking for Luke, Mammon or Leviathan. Beelzebub continues to asks where they should look next. MC could answer the planetarium, the attic room or the common room. MC and Beelzebub end up going to the attic room where they find Belphegor sleeping. MC and Beelzebub try to wake Belphegor up but he remains asleep. Beelzebub admits that he doesn’t mind Belphegor asleep, because of how long they were apart. He thanks MC for bringing their family together. Belphegor then wakes up. Beelzebub admits to Belphegor his worries of him running away. Belphegor tells him not to worry. Suddenly, Beelzebub grows hungry and leaves to get snacks from the kitchen. (20-5 and 20-8)

When Beelzebub left, Belphegor questions the MC whether or not they have feelings for Beelzebub. MC could affirm the question, say that he’s alright, or say no. Beelzebub then comes back into the room with a mountain of snacks and beverages followed by Mammon, Leviathan, Asmodeus and Satan. MC leaves the room. MC hears faint music that leads into the library as they see that Lucifer’s secret study open. (20-11)MC goes inside Lucifer’s secret study as they see Lucifer, himself, inside. MC asks Lucifer what he is listening to. He answers that he is listening to the cursed vinyl edition of The Tale of the Seven Lords soundtrack. MC could compliment the music, question about the rumour that people die listening to it or if they could listen to the music with him. Lucifer notes that he chose MC as the exchange student in this room. He notes that there were times he regretted his choice but he admits that he now thinks that he made the right choice in choosing MC as the exchange student. He then asks MC if they are finished with everything, they have set out to do in Devildom. MC answers that they haven’t made a pact with Lucifer yet. Lucifer turns into his demon form to intimidate MC. If MC chooses to run, the doors will close. Lucifer asks if they still want to make a pact with him. Regardless of MC’s answer, Lucifer will still make a pact with them. (30-13 and 20-14)

Everyone is gathered in the Student Council Room of RAD as everywhere else is empty. It is the day where Simeon and Luke leave to the Celestial Realm and MC and Solomon leave to the human world. Simeon, Luke, and Solomon leave first after saying their goodbyes. First Diavolo gives his farewell to MC, then the brothers and Barbatos say their farewells to MC before they return to the human world. The lesson ends with Solomon sending a message through his D.D.D to MC. (20-17 and 20-21)

Barbatos and Diavolo are seen in the Student Council Room of RAD as Barbatos serves Diavolo tea that he procured from the human world (A premium Ceylon tea of the finest quality). Diavolo thinks of MC as Barbatos said the tea was from the Human World. Barbatos notes that it has been quite a while since MC has went home yet everyone still seems to be in low spirits. Diavolo agrees with Barbatos that even Lucifer seems down. Barbatos questions whether Diavolo, himself, is unhappy. Diavolo said that he hadn’t thought about that, he also asks Barbatos whether he is sad that -his student and novice baking partner- Luke’s gone. Barbatos answers that he is. The scene changes to the common room of the House of Lamentation, where Leviathan and Mammon are shown. Leviathan demands Mammon to give him back his money, which Mammon refuses. Lucifer then enters the room and commands Mammon to give back his money to Leviathan until Satan enters hoping for someplace to read his book. Asmodeus then comes in the room after a misunderstanding with Beelzebub. Apparently, Asmodeus bought a very special sweet that’s only sold in limited quantities that Asmodeus was planning to post a picture of it on Devilgram to impress everyone until Beelzebub came in and ate without asking. Beelzebub apologizes about it as Asmodeus doesn’t forgive him and chokes him. Asmodeus then shouts that he wishes that MC were there to help them through their conflicts and the room turns oddly somber (as noted by Belphegor). Belphegor comes in searching for his D.D.D. which no one has seen. He is not sure where he has put it but he is expecting a call so he hopes that he’ll hear it. Asmodeus questions who Belphegor is expecting a call from as Belphegor answers that he’s expecting a call from MC as the other brothers are filled with shock, jealousy and sadness. Satan accuses Belphegor that he is making it sound like both of them have been calling on a regular basis. Belphegor affirms this accusation with (noted by Mammon) a smug face. It ends with Belphegor’s D.D.D. ringing. (20-15 Hard)

Lesson 21
Solomon tells MC to take a dagger and hold it as tight as they can and thrust it straight into someone as the screen blacks out and the scene changes to MC in the human world with Mammon calling them on their D.D.D. Mammon asks them what they were doing but guesses correctly about them walking around the streets in the Human World. MC could respond asking who was calling, how’d Mammon know they were walking on the human streets or that they are happy that he called. Mammon mentions to MC that Lucifer made everyone take turns calling MC as Satan calls him to go to a Student Council meeting. After Mammon declines, Solomon texts MC (Welcome (Back) to the Devildom!). He said that he wanted to call MC but they were on another call. He asks the MC on how they are doing then he asks, “I was wondering” and the message trails off as he surprises MC behind their back, he asks MC if they missed him and continues to drag MC back to the Devildom along with him. (21-1)

The scene changes to Devildom, where a student council meeting is being held. Mammon expresses his disbelief that he had to hang his call with MC for this. Beelzebub is next for calling MC as Mammon complains. Lucifer gets angry that Mammon doesn’t want to abide with the guidelines that Diavolo laid up for them and that he wasn’t listening to anything Diavolo just said in the meeting when Solomon appears and MC lands on Satan. Everyone else expresses their surprise as Satan asks MC why they landed on him. MC could answer that it was because of gravity, that they couldn't believe he couldn't catch them or that it's his fault for being in the way. Belphegor asks MC whether they are staying for a while but then said that their room was probably covered in dust by now. Beelzebub offers them to stay is his and Belphegor's room. Leviathan then offers MC to stay in his room as the brothers start to argue which room MC will be staying at. Lucifer gives MC the key of the House of Lamentation. (21-4)

MC and Solomon are seen at a street on Devildom chatting on their way to the House of Lamentation. Then after they reach there, MC goes inside the House of Lamentation as Solomon leaves to the Purgatory Hall. When the brothers reach home, Lucifer tells MC that they were all fighting on which meal MC would like after so long away from the Devildom. MC could answer Devildom food, human world food and Celestial Realm food. Lucifer notes that the brothers lost their cool after MC arrived back as they talk back saying he did too. After that, Mammon finished making soup and he asked Beelzebub to sample which had a “secret ingredient”. (21-6)

Mammon offers MC some soup he made again that everyone else also tried. Leviathan then say that he wanted to show MC something (Gold Hellfire Newt Syrup) that he bought from Akuzon. Leviathan notes that it was pretty expensive but he wanted to display it in his room so he bought it. Lucifer asked why he wanted to display an empty bottle in his room as Leviathan is shocked that the bottle is empty. Mammon said that it was his “secret ingredient” to his soup. Leviathan grows angry at Mammon for taking it. Mammon said that he thought Gold Hellfire Newt Extract sounded good so that was why he used it. Leviathan retorts saying that it’s not an extract but a real-life product modelled after “dragon fog” from TSL. The secret remedy of Dragaul folk. Asmodeus notes that it’s made using newt caught on fire and burned to crisp in the human world, and were later reincarnated in the Devildom. Satan asks Leviathan what the syrup’s effects are as Leviathan says that it wasn’t just Regular Hellfire Newt Syrup but it was the regular person which was when he realises something and he stays silent as his face turns red. He starts acting odd and tells MC to stay away from his room as he runs away. (21-9)

MC is seen in the library as they find Satan there. Satan says that he knows an illustrated reference book that probably has the information to the effects of the syrup but it is not in the library so he invites MC to go to his room to find it. Satan tries to find it as MC helps him. They eventually find it as Satan reads the book. The term “hellfire newt” refers to a newt reborn in the Devildom after being consumed by fire in the Human World. Hellfire newts are mainly used in remedies and elixirs meant to restore and revitalize the body as well as stimulate sexual desires. A number of different remedies contain hellfire newt as an ingredient and one of the most well-known of these is called ‘Gold Hellfire Newt Syrup’. When consumed by demons, Gold Hellfire Newt Syrup causes a state of infatuation. More specifically, it works as a potent aphrodisiac, causing demons to experience very powerful sexual urges. Notably, this heightened sexual desire is felt towards humans only. It is currently unknown why the effect is limited to humans. The syrup’s effect wears off after a few days in the majority of cases. In certain instances, however, it is reported to have persisted for upwards of two hundred years. If a demon has forged a pact with a human, the syrup’s effect can be neutralized by carrying out an order issued by the human master. Presently, this is the most effective known means of curing demons of its influence. Satan asks MC whether they would like to find out just how powerful the effect of the syrup really is. He continues to ask MC if they missed him. He backed MC up a giant pile of books as the floor is now littered with books which all seemed to be about cats as MC orders him to do something for them. MC could order him to hug them, kiss them or meow for them. The effects of the syrup wash off from Satan after doing what MC orders. He warns MC that the syrup is very powerful and that they have to make sure that the others won’t find them. (21-11 and 21-14)

MC walks from Satan’s room as they bump into Beelzebub. He asks MC whether they want to come with him to the kitchen. Regardless of MC’s answer they go there. Beelzebub confesses that he misses them when they left the Devildom. He went reminiscing with MC about the retreat at the Demon Lord’s Castle until the aphrodisiac starts to take effect on him. MC grabs a cream puff to tide Beelzebub over which is found out to be Belphegor’s and apparently it was cursed so that it would explode if anyone else touched it. The whip cream goes all over MC as then they can order Beelzebub to get it off their lips, hands or to grab them a towel. After the effects disappear, Beelzebub apologises for putting MC through that. Belphegor then enters the room, angry at the fact that his cream puff was touched. (21-17 and 21-20)

Simeon texts Lucifer (Hello from the Celestial Realm), asking him about how long it has been since Luke and him has been in the Devildom and about how’s it going. Lucifer answers that things are as “the same as ever”. Luke then enters the room as he asks Simeon who he was talking to. Simeon greets Luke as he answers that he wasn’t talking to anyone. Simeon continues the conversation by asking what did Michael say. Luke answers that he wanted to talk about making changes to the Eastern District inspection schedule. Simeon notes that Luke looks “sort of depressed”. Simeon question if this is because Luke misses the life in the Devildom. Luke dismisses the idea immediately. Simeon gives his personal opinion, mentioning he misses the Devildom. Solomon then texts Simeon (Hello from the Celestial Realm 2), telling him that he’s in the Devildom with MC. Simeon then announces it to Luke, that Solomon and MC are in the Devildom. (Hard 21-16)

Lesson 22
Belphegor gives them a hard scolding before he storms. Beelzebub urges MC to go chase after Belphegor. MC finds Belphegor on the stairs to the attic as he admits he just can’t be around them because the syrup had started to take effect. Belphegor goes in the attic as MC is outside the door. MC tries to convince him to let them in as Belphegor eventually complies. Belphegor warns MC that just because he lets them in, doesn’t mean all is forgiven. Belphegor says that if MC wants to be forgiven, they have to do whatever he wants, no matter what it is. MC gives Belphegor a massage. Belphegor tells MC that they are good at massaging. MC suddenly tickles Belphegor; he tickles MC back. MC will tell him to stop as the syrup’s effects are cancelled. Belphegor asks MC to give him another order. MC could order him to kiss them, hug them or hold their hand. (22-1 and 22-5)

Beelzebub texts MC that Asmodeus was looking for MC. MC is seen in the hallway as Asmodeus appears. He accidently pushes MC to the ground. MC orders Asmodeus to get off him as he does so. Suddenly, Asmodeus starts wheezing. MC helps Asmodeus get to his room. Asmodeus admits that he didn’t feel like going outside, even when he was invited to parties, when MC was gone. He also notes how he couldn’t sleep well without them. He says that he’s going to die from the tightening in his chest so he wants to ask MC one last question: He asks them of how they feel about him. MC could answer that they love him; they don’t really feel anything about him and they think of him as a dear friend. He also gives MC a last request: To put their arms around him. Asmodeus tickles him as MC orders them to stop. Asmodeus finally gives up the act and told MC that the effects of Gold Hellfire Newt Syrup were already cancelled from when MC ordered him to get of them. He also admits that he doesn’t need an aphrodisiac to get smitten with them. Lucifer then enters the room. (22-7 and 22-10)

Lucifer gives MC a package that was addressed to Leviathan but got served to his room instead. He requests MC to go give the package to Leviathan. Asmodeus ask Lucifer how he isn’t affected by the syrup. Lucifer answers that something like that would not affect him. MC goes to the hallway as Lucifer leaves. MC knocks at Leviathan’s door as he asks for the secret phase. The correct answer is the second lord. MC enters but Leviathan stops MC and asks them to not come any nearer because he’s afraid that the Gold Hellfire Newt Syrup might take effect. Leviathan knows that the aphrodisiac is very powerful so he doesn’t trust himself around with MC but suddenly he throws his arms around them and admits that he missed them every single day. He then asks MC to give him an order. MC could order him to kiss them, hold them even closer or to back away from them. Now that the order neutralized the syrup’s effect, Leviathan invites MC to game with him but then Mammon texts MC a bunch of emoji spam (You Never Forget Your First). (22-12 and 22-15)

MC goes to see Mammon. Mammon gets angry at MC about going to the other rooms first instead of his. He admits that he has been thinking of MC as much as he’s been thinking of schemes to make money. MC can order Mammon to kiss them, hug them or shake to cancel the effects of the syrup. Diavolo then texts MC to tell them that he has arranged for their stay in the Devildom (You Never Forget Your First 2). (22-18 and 22-19)

Lucifer texts MC (Maintaining the Façade) to go the library concerning about Diavolo’s message. Lucifer asks MC to sign some papers for their stay in the Devildom. Lucifer checks MC for dangerous items. He then asks MC to pass his papers as he suddenly blushes. Lucifer then tells MC to warn him before they touch him. It is found out that the aphrodisiac does affect him. He asks MC to give him an order. MC could order Lucifer to kiss them, hug them or stay down. The effects of the syrup git cancelled. Then they suddenly hear screams. Which Asmodeus said was about the Gold Hellfire Newt Syrup. Apparently, Leviathan had another bottle of it stashed away that Mammon tried to steal but Leviathan caught him and tried to stop him. They got into a fight, one thing led to another, and now both of them are covered with syrup. Lucifer doesn’t want to be indulged with this and asks MC not to be either. (22-A and 22-C)

Lesson 23
Luke and Simeon text MC to invite them to the Celestial Realm along with Solomon (Let’s Go to the Celestial Realm!1). MC confronts Diavolo at a hallway at RAD about it as he says that it has already been discussed about. The scene changes with MC and the brothers (excluding Lucifer) in the dining room of the House of Lamentation. Mammon expresses shock hearing the news as most of the other brothers show a longing to go to the Celestial Realm. Satan dismisses the idea of all of them going to the Celestial Realm together so Belphegor raises the idea of one of them going to the Celestial Realm with MC. Mammon gives the idea of using cards to decide which of the brothers to come with MC. (23-1) MC eventually picks Mammon’s card but it is found out that he actually tricked everyone using the cards as they are all his cards. Lucifer then enters the room completely crushing the idea of any of the brothers going to the Celestial Realm. Solomon texts MC that he is heading to the Demon Lord’s Castle and that he will see MC later (Let’s Go to the Celestial Realm!2). The brothers bid MC farewell as MC heads off with Lucifer. (23-3)

The scene shifts to MC and Lucifer arriving at the Demon Lord’s Castle. MC can state that they are excited, scared or nervous to be going to the Celestial Realm. MC’s choice effects the intimacy level. Lucifer bids them goodbye as Solomon and MC follow Barbatos to the garden to enter the Celestial Realm, leaving Diavolo and Lucifer. Solomon and MC arrive in the Celestial Realm as Solomon mentions that it is his second time entering the Celestial Realm. A voice calls out to them as it is found out to be Luke along with Simeon. (23-5)

Luke offers MC an apple cream tart that he made himself. Solomon mentions that he is jealous of Simeon of eating Luke’s sweets as Simeon mentions that it is not as easy as it seems. Luke seems bothered by this remark as he mentions that if Simeon were to complain he wouldn’t give any of it to him. Luke changes the subject and states to MC that Michael wanted to meet them. Solomon asks Luke if he thinks whether or not if Michael would mind him calling him “Mike”. Luke answers no directly, obviously bothered by the question. Simeon mentions that he actually wanted to introduce Michael to the them but it wasn’t possible because of an urgent problem. Solomon mentions a sort of “news” that MC and Luke aren’t aware of, that they are scheduled to head back to the Devildom, as part of a short-term program to observe how things work there. Luke shows his utmost surprise hearing it. Luke asks why Simeon didn’t tell him as he answers that he wanted it to be a surprise but ended up forgetting to tell him about it at all. Then they all return to the Devildom. (23-7)

Beelzebub is shown pleased with Simeon and Luke’s return. Asmodeus guesses that this is because he gets to eat the stuff Luke bakes again. Lucifer finds them and announces that they will be having a student council meeting and that MC has to come. It is found out that they are gathered to discuss about the school festival event. They start by selecting a school festival committee leader, Diavolo selects MC to be the leader. MC could respond saying it sounds like fun, that they don’t think they’ll be able to do it or to ask why he has selected them. The intimacy level is affected by MC’s choice. The first task is to question what will they do. Diavolo then realises something and confronts to Lucifer about it, that they are one officer short. Belphegor skipped the meeting without permission. (23-10)

Lucifer orders everyone to find Belphegor or they won’t be getting dinner. Lucifer excuses himself with his workload, so does Leviathan, Mammon and Satan. Before Asmodeus excuses himself, Beelzebub stops him. MC could respond to all of it saying good luck, that they’ll help or excusing themselves. The three of them search but Belphegor is nowhere to be found at RAD. (23-12)

They then start searching for Belphegor in the House of Lamentation. Asmodeus suggest for the three of them to split up in order to cover more ground in finding Belphegor. Beelzebub and MC, however, sticks together. Beelzebub questions MC where to search Belphegor next. MC could respond to search for Belphegor in the library or Asmodeus’ bathroom. The intimacy level is affected by the choice MC makes. If MC chooses to go to the library, they find Satan reading with Beelzebub nowhere to be seen. If MC chooses to go to Asmodeus’s bathroom, they find Asmodeus singing and cleansing his skin instead of searching for Belphegor. The scene then shifts to Beelzebub and MC in the hallway. Beelzebub searches his and Belphegor’s room leaving MC as he suggests MC search somewhere else. (23-16)

MC enters the attic where Belphegor is found waking up. Belphegor jokes around saying that it was a shame that he didn’t know it was MC coming in. He says if he’d known he would’ve kept sleeping so it would seem as in one of those situations where the only way to wake Belphegor up is to kiss him. MC could respond saying that they could kiss him right now, to ask if his brain’s still asleep or to say that they don’t follow him. Beelzebub and Asmodeus then enter the room. Asmodeus reminds Belphegor that he missed the student council officer’s meeting. Belphegor responded saying that it wouldn’t matter if he was there or not. Asmodeus then suggest they all go downstairs. They leave the room leading to the library but ends up in the music room. Belphegor notes that he didn’t have any signal in his D.D.D. too and they all puzzle about what could be happening. (23-19)
