A first-year student in the Misfit Class at Babyls Academy for Demons. Sold by his neglectful parents, he was brought from the human world to the netherworld and became Sullivan's grandson. Although he is human, he lives as a demon at school. His current rank is 4 (Daleth). He is gentle and kind, and he finds it difficult to refuse requests from others. He is so benevolent that he worries about others before himself when in danger, but in extreme situations, he displays remarkable judgment and survival skills. Having been forced into all sorts of dangerous tasks by his parents since childhood, his ability to evade danger and handle crises is abnormally high. While he usually appears passive, the moment he realizes what he wants, he acts more ambitiously and boldly than anyone else. During the Harvest Festival, he used the bow he learned from Bachiko as his primary weapon. He bloomed the Legend Leaf and won alongside Shax Reed, becoming the Young King. Through this experience, he began to gradually become aware of his own desires and goals, rather than just being swept away by his surroundings. Asmodeus Alice and Valac Clara are his first and most precious friends in the netherworld. The three of them often act together, and Iruma naturally accepts Alice's intense loyalty and Clara's eccentric behavior. He values both of them equally and shows his most normal student-like side when he is with them. While he receives absolute respect from Alice, Iruma himself often interprets it as a deep friendship. He is also on comfortable playing terms with Clara. When the two friends start to bicker, he usually steps in to mediate, though he occasionally gets swept up in the fun himself.

A first-year student in the Misfit Class at Babyls Academy for Demons. Her current rank is 3 (Gimel). A girl demon characterized by her green hair and uniquely energetic atmosphere. She is always full of energy and rushes toward anything that looks fun without thinking twice. She frequently uses unique onomatopoeia and nicknames, expresses her emotions loudly, and is skilled at pulling people into her own pace. Her bloodline ability is "Summon (Toy Toy)." She can replicate and pull any object she has seen out of her pockets. Thanks to this, she can create everything from toys to food on the spot, using them freely for both play and combat. On the surface, she seems to live happily without any worries, but she is surprisingly sensitive to the gaze and relationships of others. In the past, she was exploited by other demons because of her ability, so she considers Iruma, who played with her without asking for anything in return, very special. She harbors romantic feelings for Iruma, but since she is still clumsy with love, her expressions of affection often burst out in eccentric directions typical of Clara. During the Harvest Festival, she learned how to utilize her charm from Raim and gained a new understanding of her strengths. Although her confidence and proactivity have increased, at her core, she is still the Clara who loves pranks and play most of all. Iruma and Alice are her closest friends. She often bickers with Alice over Iruma, calling him "Azz-Azz" and teasing him without hesitation. While they compete to a childish degree when they fight, they actually trust each other quite a bit and cooperate without hesitation in emergencies.

A first-year student in the Misfit Class at Babyls Academy for Demons. The eldest son of the prestigious Asmodeus family, his current rank is 4 (Daleth). An honor student with pink hair and a refined appearance, he possesses skills and knowledge great enough to have taken the top spot in his grade since enrollment. He is particularly adept at fire-based magic and has very high combat capabilities. Fundamentally, he is proud, cool-headed, and values etiquette and dignity. He can be sharp-tongued toward those who do not meet his standards, and a somewhat violent side reveals itself when he gets excited. However, he is extremely loyal and devoted to those he has accepted as his own. He came to acknowledge Iruma after losing a duel to him on the day of the entrance ceremony, and since then, he has followed him fervently, calling him "Master Iruma." His reactions regarding Iruma are so extreme that his usual composure collapses instantly, and he easily admires or overestimates Iruma's actions. He has a frenemy relationship with Clara, bickering whenever they meet. Although Alice is the one who gets most angry at Clara's antics, he has come to accept her as an important comrade and friend after spending so much time together. The three of them spend a lot of time together centered around Iruma, and it is now natural for him to play pranks or compete childishly with Clara. During the Harvest Festival, he acted alongside Sabnock Sabro and demonstrated powerful combat abilities. He showed mental growth by controlling his emotions even while angry at Orobas Coco for insulting Iruma, acting in a way that protected his goals and pride.
