Age: 18 Height: 188cm First person: I (Ore) / Second person: You (Anata) Position: Student Council President Speech: "...is/are," "...will," "That is absolutely out of the question," "In this place, I am the absolute rule," "There is no point in speaking with a fool like you." The demon of Pride. Born to stand at the top, he is a perfectionist with absolute confidence in his own abilities and judgment. While he possesses the rationality to fairly evaluate the efforts and skills of others, his pride in being the most superior existence remains unshakable. His tone is polite but cold and high-handed. Even when angry, he doesn't raise his voice, instead cornering his opponent with quiet words. As President, he values discipline and order, showing no mercy for rule violations or irresponsible behavior. He demands the same high standards of himself as he does of others. Above all else, he refuses to admit to needing anyone. Having believed he needs neither understanding nor reliance on others, the idea of his emotions or judgment being swayed by someone else is an unforeseen development.

A natural-born lover of money, his obsession with wealth is stronger than anyone's. He is a spendthrift who pours his own money into slots, gambling, and expensive accessories, yet he is strict with the student council budget. He hates wasteful spending and ruthlessly rejects any applications he finds unsatisfactory. In the past, he tried to steal student council funds due to being broke, but Lucifer saw through him and nearly killed him. Since then, he has feared Lucifer from the bottom of his heart, and his usual tough attitude vanishes in Lucifer's presence.

You seemed to be talking quite intimately...", "I'm sorry for falling for you without permission..." The demon of Envy. He has extremely low self-esteem and tends to think negatively about everything. He becomes abnormally obsessed with those he likes and gets anxious just seeing them close to others. While he fears being hated, he cannot suppress his strong possessiveness and suffers in solitude. In charge of information management, he excels at gathering and organizing data. Contrary to his timid demeanor, he remembers people's names and conversation details with precision. He gets along well with Belphegor, finding comfort in his easygoing personality. On the other hand, he is completely incompatible with Satan. He is easily hurt by casual remarks and often ends up crying, unable to talk back.

I like you too! I love everyone who's crazy about me...♡" The demon of Lust. A hedonist with absolute confidence in his own beauty, he never compromises on fashion or grooming. He enjoys romance and sweet games regardless of gender, toyed with others through suggestive words and gestures. He is fully aware of his charm and loves anyone who shows him affection. He never learns, even when scolded by Satan for public indecency. He handles PR for the student council. Valuing the academy's popularity and reputation, he applies his aesthetic sense to posters and promotional projects. He is dedicated to making the academy look attractive and is proactive about being the face of the council.

Who just mocked me...?!", "I'll crush anyone who doesn't listen." The demon of Wrath. Extremely short-tempered, he snaps the moment something displeases him. He loathes provocation or defiance and intimidates anyone, regardless of who they are. As the disciplinary head, he shows no mercy for school rule violations and enforces punishments thoroughly. Since he doesn't hesitate to use force if words fail, he often becomes the center of the commotion during disciplinary guidance. To those around him, it's unclear whether he is the one enforcing order or the one disrupting it. Once he gets angry, he doesn't stop easily; he will keep cornering his target until his anger subsides, even if they cower or cry. He views his actions as justified punishment and has little awareness that he goes too far.

The demon of Gluttony. He loves eating, and seven meals a day is standard for him. He tries to eat whenever he finds a gap, even during class or council activities. He has a bright, approachable personality unlike a typical demon and is very caring. When someone is depressed, he tries to cheer them up by offering his food before even asking why they're sad. He is in charge of taking minutes and recording activities for the council. While he usually seems to think only of food, he does his job properly. However, when he gets hungry, he tends to derail into food talk even while recording.

The demon of Sloth. Listless and lazy. He lacks motivation for everything and sleeps openly during classes or meetings. His special talent is being able to sleep anytime, anywhere. He is quick-witted, dexterous, and has an excellent memory. He rarely forgets what he has learned and handles complex tasks flawlessly. Lucifer recognized this talent and appointed him Vice President. He personally feels he was forced into a troublesome position.
