Main Character

  WARNING ! This page contains  MAJOR SPOILERS . Read at your own risk.

The Main Character (aka MC) is one of the two human exchange students attending RAD alongside Solomon. Their default name is Yuki, however, the player can change this name alongside their birth-date at the start of the game.

Appearance
Although MC's physical appearance completely depends on the player, the demon brothers have noted that they are kind of cute and hard to dislike. Asmodeus provides a few of MC's features in Lesson 8-15, such as their ring fingers being longer than their index fingers, and their ears being on the small side.

After the start of season three (Lesson 41), On the back of MC's hand there's a tattoo of three staves and seven stars, which symbolizes the Sorcerer's Society. According to Solomon, the stars represent the seven virtues: temperance, gratitude, chastity, humility, generosity, patience, and diligence.

Personality
MC's personality is determined by the responses and actions they make during the Main story, Event stories, chats, and calls.

However, due to the machinations of the game, MC is often considered nosy due to their tendency to get into matters that, at face value, appear to have nothing to do with them. This trait is often viewed as a detriment by other characters.

In Lesson 4-15, Lucifer commented that MC seems to be "the type of person that has trouble lying."

Mammon once lamented, during Lesson 16-A, that MC "may seem like someone who's really got it together", but has a "boneheaded streak", and that they can be "weak, and super reckless...and too damn gutsy". The recklessness is later confirmed, as they frequently choose to head toward danger rather than away from it.

It is implied in Lesson 17-7 that MC does well at card games. There is an option to downplay it, but Belphegor will believe they are only saying that because they felt sorry for him.

They have a tendency to be too overzealous when they enforce the pacts on the brothers.

According to Simeon, their greatest strength is being flexible and being able to adapt to almost any situation.

In the chat Lend Me Your Textbook, Beelzebub mentions that MC always keeps their room clean.

Story
(spoilers ahead)

Background
The majority of MC's background remains unspecified, with the only backstory being that they were picked randomly by Lucifer to be part of the exchange program at RAD. Apparently, they also had no knowledge of being chosen, for they were confused at appearing suddenly within the Devildom's student council hall.

While Lilith is eventually revealed to be MC's distant ancestor, neither they nor Lilith are genetically related to any of the seven brothers, by blood or otherwise. This is because — as angels that were created, not born — none of the brothers are related by blood to begin with. The brothers choose to see their relationships to each other as just that: brothers. This is also why Satan is considered one of the seven "brothers" despite the history of his creation.

Main Story and Events
The order of the demon brothers who made pacts with MC from first to last goes as follows: Mammon (Lesson 2-8), Leviathan (Lesson 4-6), Beelzebub (Lesson 6-10), Asmodeus (Lesson 8-15), Satan (Lesson 12-10), Belphegor (Lesson 18-19), and finally Lucifer (Lesson 20-14).

In Lesson 5-7 (Normal), it was revealed that MC's room is directly behind the kitchen. A large part of their room was also destroyed after Beelzebub destroys the kitchen wall connected to their room.

MC has so far developed kemonomini traits three separate times. The first was in We're All Bad Here, where they developed bunny ears after eating one of Simeon's cookies. The second was when MC has the choice of being a dog or rabbit as a game avatar in the Devilgram Animal Game. The third was in Lesson 53, when MC was magically given a sheep's tail to play the game Tail Thieves.

In Lesson 41, MC was revealed to be studying the magical arts with Solomon serving as their teacher. From Lesson 45 onward, MC underwent seven trials to earn their sorcerer's license. By the end of Lesson 58, MC officially became a sorcerer, though they are still under Solomon's apprenticeship. In Lesson 62-19, Lucifer states that there are probably only a few demons who could pose a threat to MC due to how powerful they have become. In Lesson 64-17, MC was able to successfully teleport themself and Beelzebub despite it being the first time they teleported more than 1 person. In Lesson 70-17, MC was able to summon Lucifer into the Human World which requires a large amount of magical power. In Lesson 74-17, MC was able to accurately summon Lucifer into Raphael's dream world even though the paths to the dream world are very unstable.

In Lesson 62-17, Diavolo asks MC to become a student council officer. However, there are demons that are against MC becoming an officer since no human has ever become an officer before. Therefore, Diavolo asks MC to complete a preliminary task to prove their worth before doing the 3 trials that are required to become a student council officer. If MC failed the preliminary task, then their status as an exchange student would also be revoked. The preliminary task involved MC finding a specific card imbued with magic amongst all the fake cards scattered around RAD. Throughout Lessons 62-64, MC finds various fake cards, but MC finally successfully finds the specific card that Diavolo hid after getting some hints from everyone. In Lessons 65, MC begins the 1st trial of becoming a student council officer. Diavolo tasks MC to work together as a team with the new exchange students, Thirteen and Raphael, for the RAD Sports Festival. In Lesson 66, MC completes the task after all 3 of them work together to defeat the chimera that was summoned after Mammon threw a grimoire on the ground which contained a magic seal for summoning a chimera. In Lessons 71-72, MC is told to compile a report on how the demon students view the exchange students and interview the exchange students in regards to their experience at RAD. However, this is a cover for the true 2nd trial which was for MC to solve one of RAD's problems out of a genuine sense of caring instead of being told to solve it. MC and Mephistopheles end up solving the mystery, so MC passes the 2nd trial.

Relationships
Because MC's relationships vary depending on the player, this section is for listing moments or interactions with MC and the other characters that are both immutable and noteworthy.

Lucifer

 * In the Dark Santa Pop Quiz, Lucifer gifted MC a rose from a completely new genus which he crossbred himself, using magic so that the rose wouldn't wilt for a year.
