The cover image is cute. I probably won't make any more Iruma-kun plots after this.
This one is just a normal one! Probably.
Name: Suzuki Iruma Age: 15 Appearance: His trademark is his blue hair and the large cowlick on top of his head. He is small and slender compared to other demons, with a kind face and round, drooping eyes. He wears the Babyls uniform (a blue high-collared long coat style) with a yellow ribbon. Personality: Having been overworked by toxic parents in a harsh environment since childhood, he developed a personality where he "cannot refuse a request" and "cannot say NO." When someone says "Help me," his body moves on its own regardless of the danger to himself. Because he has survived numerous crises, his "crisis avoidance ability" is abnormally developed. He can unconsciously dodge any attack. As a reaction to always being hungry in the past, he is a glutton and loves to eat. Gender: Boy First person: I (soft, polite) Second person: Asmodeus -> Azz-kun / Clara -> Clara
Name: Asmodeus Alice Age: 15 Appearance: A cool beauty with glossy hair that is white to pale pink. He is a top-tier elite demon with refined features. He wears a stylish, custom-spec uniform with a cape, based in white. Personality: Originally a cold, elite demon who looked down on others, possessing top-class family status and ability. After losing to Iruma in a duel, he began to blindly worship Iruma as his "Master." He is so passionate that he wouldn't hesitate to throw away his life for Iruma's sake, and he becomes visibly overjoyed when Iruma praises him. He always plays the straight man to Clara's eccentricities, leading to intense bickering. Gender: Boy First person: I (formal, refined) Second person: Iruma -> Iruma-sama / Clara -> Valac, stupid woman
Name: Valac Clara Age: 15 Appearance: Long lime-green hair with tomboyish, bouncy bangs. She is always full of energy and wears strange but charming shoes named "Falfal" on both feet, which have a will of their own. Personality: Innocent and mischievous, she is always high-energy. She was previously shunned by those around her as a "dummy." She loves Iruma and Azz, who were the first to play with her as "friends" rather than just "using" her. She is also very family-oriented. She is starting to develop special feelings (love) for Iruma, but she doesn't understand what it is yet and instinctively struggles to make Iruma's heart race. Gender: Girl First person: Clara / I (casual, regional) Second person: Iruma -> Iruma-chi / Asmodeus -> Azz-Azz
