Lucifer

"The perfectly flawless but malicious sadist. The mighty first-born."

"'Known in the Devildom for being Diavolo's close friend and right-hand man. He is the oldest of the 7 demon brothers. He keeps the brothers together, by force if necessary.'"

Lucifer is the Avatar of Pride and is the eldest among the seven demon brothers. He is one of the main characters in '''Obey Me! One Master to Rule Them All''' that is also involved in the intimacy system of the game, therefore, users can interact and raise their relationship with him.

Appearance
Lucifer is the second tallest of the seven brothers, almost reaching Beelzebub's height. He has black hair that's parted on the right side of his face, and black eyes with a red gradient. Like all of the demon brothers, Lucifer paints his nails and specifically wears red nail polish.

Personality
The eldest of the brothers and hence is the leader of the household, Lucifer presents himself as a calm, composed, and intimidating person. His brothers frequently comment on how scary Lucifer can be. He is a very strict and unforgiving demon and does not hesitate when doling out punishments to his younger brothers.

His sadism is evident in his punishments. However, despite being so uptight, he still makes an effort to joke around with his brothers, especially when it comes to teasing Mammon - who the other brothers say he has a soft spot for.

As the Avatar of Pride, he displays a tremendous sense of pride. Several examples include that when he was trapped inside Satan's body, he refused to let his brother give the speech in his body for he worried that Satan would ruin his reputation, and was displeased at the fact that he needed Satan (in Lucifer's body) in order to travel to the human world since he couldn't pass through the seal.

Lucifer has sworn utmost loyalty to Diavolo, the future king of the Devildom and his closest friend, going thousands of years back. The demon brothers, especially Satan and Belphegor, often accuse Lucifer of caring for nothing but Diavolo and maintaining Diavolo's good image and reputation.

Being the eldest, Lucifer is also the strongest of the demon brothers. This was proven during the pillow fight in the Demon Lord's Castle, when he, after losing his cool, bore a hole through one of the beds just by throwing a pillow (Lesson 8-19). He is also capable of resisting the effects of powerful potions, either due to his power as a demon or through his own sheer willpower. He was able to maintain his self-control after eating a potion-laced cake that gave him animal traits and instincts in the Pop Quiz Event, Paws and Claws.

Lucifer also tends to be subtly overprotective of his brothers, proving in his own way that he cares for them. His overprotective nature is often perceived as more suffocating and controlling rather than comforting. Mammon frequently complains about this attitude of Lucifer's to MC and to the others. Despite everything, Lucifer genuinely wants what's best for his brothers.

As seen in the Devilgrams Lucifer the Demon of Rock and Piano Timbre for You, he is skilled in playing multiple instruments. These include the piano, violin, and guitar. He's also willing to take on unfamiliar ones, such as the drums.

Story

Background
Lucifer and his brothers used to be angels who lived in the Celestial Realm. Lucifer was a high-ranking angel who was also known as The Morning Star, unequaled in beauty and respected by everyone.

An incident regarding his youngest sister Lilith, who broke a rule from the Celestial Realm by giving food from their world to a human she fell in love with, led their Father to make the decision to have her obliterated. This made Lucifer brutally angry, and his attempts to stop this eventually made him lead a revolution against God, with various other angels and his siblings on his side. This conflict would become known as the Great Celestial War, in which Lucifer and his siblings lost and were banished from the Celestial Realm and landed in the Devildom.

It was then when Lucifer, overtaken by his wrath and his hatred towards their Father, tore away two of his former six angel wings, which resulted in Satan's birth. This is mentioned by Luke in the main story and in Satan's Devilgram The Search for Self.

Lilith was severely injured and had no chance of surviving after being attacked in the War. Already in the Devildom, Lucifer begged Diavolo to save her life. Diavolo said that the most he could do would be to make her start again by reincarnating her into a human, but Lucifer and his brothers would never be able to go see her and remind her of her past life. Lucifer would also have to pledge absolute loyalty to Diavolo in return, to which he agreed.

Lilith was born again as a human, and Lucifer and his brothers transformed into demons. Lucifer thought it was best for his brothers not to know about Lilith's real destiny since they would have to live with the pain of not being able to ever see her again, so he suffered the truth in silence all by himself, letting his brothers believe Lilith died as an angel.

As an angel, he used to speak quite harshly, bordering on rude in some instances, but was still very direct and honest about his feelings. Now as a demon, the events that led to his current existence soured his relationship with his past home; his greatest fear is dying and ascending back to the Celestial Realm, as he states in Satan's Devilgram Be You.

Main Story and Events
At the beginning of the game Lucifer is introduced by Diavolo and proceeds to explain the details of the exchange program to MC. He states that, if anything shall happen to MC, it would be the student council's responsibility. He introduces several other characters as the story progresses.

After MC attempts to climb the stairs that led to the attic and the source of the mysterious voice that they keep hearing, Lucifer attempts to stop them and claims that it was no place for humans because of the imminent danger it held. He later sends MC back to their room and further stresses that his word was law.

When MC and Leviathan had a competition to prove who was the biggest TSL fan, Leviathan loses control and attempts to attack MC while in his demon form. But Lucifer takes his demon form as well and saves MC at the last minute, which his brothers express surprise in and offhandedly say is something he hasn't done in a long time. He sends Leviathan back to his room to cool off. He later says it is his duty to clean up messes caused by the recklessness of his younger siblings. The fact that Lucifer saved MC from Leviathan makes Mammon jealous.

After MC makes the pact with Leviathan, MC heads to Lucifer's room and hands him a copy of the TSL soundtrack that they had obtained from Leviathan. Lucifer is surprised and explains his interest in the soundtrack. He hints to MC that he would be listening to the soundtrack for the rest of the night but still reminds them not to go up the stairs leading to the attic. With Lucifer now distracted, MC makes their way to discover the identity of the person behind the mysterious voice.

Shortly after discovering Belphegor in the attic and figuring out his true identity, MC eavesdrops on Lucifer and Beelzebub's discussion about Belphegor and his current position as an exchange student in the human world with Beelzebub attempting to persuade Lucifer to allow him to come home. Lucifer asks Beelzebub who he would rather side with, him or Belphegor.

Mammon, also eavesdropping, tells MC that the brothers were once angels who resided in the Celestial Realm but it all changed after they fell and arrived in the Devildom. After swearing loyalty to Diavolo, Lucifer would follow his every command, at any cost.

After MC's discussion with Beelzebub about his past, MC receives a call on their D.D.D. from Mammon, frantically asking that they make their way to the basement with haste as Lucifer is about to attack Luke due to his suspicion that Luke had intended to steal a Grimoire (a book important to the demons). He reveals his true form and goes to attack Luke and Beelzebub for harboring Luke without his permission, but MC steps in to protect them. Lucifer nearly attacks MC, but Diavolo stops him.

The next day, Lucifer invites MC to meet him in the music room before the start of classes.

Main Character
Lucifer is the only one of the brothers so far that has attempted to attack MC more than once. The first time was because MC jumped in to shield both Luke and Beelzebub from him in Lesson 6. The second time was when he found out that MC had been secretly meeting with Belphegor in the attic.

Lucifer is the last demon out of the seven brothers that MC makes a pact with, but Lucifer notes MC shouldn't lump him together with the rest and that he won't be MC's possession.

According to the chat First Thing in the Morning, the first thing Lucifer does every morning is check his D.D.D. for messages from MC. In the Dark Santa Pop Quiz, he gifted MC a rose from a completely new genus which he crossbred himself, using magic so that the rose won't wilt for a year.

Mammon
One could say that Lucifer's treatment of Mammon is the harshest of all his brothers. Lucifer punishes Mammon in various ways, such as taking away his credit card or hanging him from their house's ceiling. He often gets mad at Mammon as the latter tends to cause a lot of (usually finance-related) problems.

However, Lucifer also has a soft spot for Mammon. This is shown across multiple occasions via the story and chats, and other characters (like Simeon or Diavolo) comment about it as well. In one chat, he even spoke against Diavolo, something Lucifer seldom does, in order to defend Mammon.

In the Devilgram story The Rulebook, he also tells Mammon it's thanks to him that Lucifer turned out this way. In a flashback, it's revealed that Mammon gave Lucifer the advice to act like he knows better than anyone and be so proud that people around him will think he's full of himself.

Belphegor
Lucifer cares for Belphegor deeply, and possibly blames himself for what happened to their relationship. Conflicted between his loyalty towards Diavolo and his brothers, he locked Belphegor away in order to protect him from Diavolo's possible punishment. During the time Belphegor was locked away in the attic, Lucifer often visited him, trying to change Belphegor's mind.

Diavolo
Lucifer respects Diavolo greatly and shows unwavering loyalty towards him, which sometimes causes conflict between him and his brothers, especially Belphegor. He rarely opposes Diavolo, even if he personally disagrees with Diavolo's plans (or finds them ridiculous in most cases). The relationship between the two also ins't always perfect, as in season two of the main story when Lucifer is bothered by the fact that Diavolo is hiding something from him. Although he's willing to secretly investigate after Diavolo, he also ultimately respects Diavolo's decisions and doesn't press the matter when Diavolo tells him not to worry. At the end of season 2, after finding out the truth, Lucifer gets mad at Diavolo and seems unwilling to forgive him all that easily, despite Diavolo's attempts to mend things between them.

For the most part, however, he and Diavolo are close friends and the two often visit each other to have tea together. MC is eventually a regular guest to these tea parties, as noted in the chat Secret Ingredient. Two two also play chess together often, with Lucifer never able to beat Diavolo, as revealed in The Glory Days Devilgram.
