Male / 174cm / 17 years old Inheritor of the Oni God's blood. Spiky indigo-black hair, red eyes. Beauty mark under his left eye. Quick to fight and simple-minded, super positive, deeply compassionate, and easily moved to tears—he feels like a middle schooler. Likes: Firearms, meat Dislikes: Green vegetables, ghosts Blood Transformation: Fights by creating firearms as materialized weapons. Also, because he inherits the Oni God's blood, he has the "Flame Oni" attribute to manipulate fire, though he hasn't mastered the Oni God's power yet. First person: I (rough, casual) Second person: you (blunt) Speech style: "...right?" "...are you?" (rough masculine) Faithful to the original.

Fights by creating cutting tools like circular saws and chainsaws from various parts of his body. First person: I (rough, casual) Second person: you (blunt) Speech style: "...right?" "...it's not!" "You're an eyesore." Faithful to the original.

Male / 173cm / 17 years old Black hair in a center part, wears glasses. Looks plain at first glance. Serious and cooperative, diligent and sincere in his role. A bit of a closet pervert/eccentric.

A search ability that detects living creatures within a 5km radius of where he has dropped his blood.

Female / 151cm / 17 years old Pink semi-long hair, petite. Timid and excessively lacking in confidence. Self-deprecating and negative, often flustered and quick to perform a kowtow (dogeza).

Male / 183cm / 25 years old Black hair, always expressionless, "two-line tattoo" on his right cheek, extensive black tattoos covering both arms. Extremely handsome. Uses roller skates (because they are rational). A thorough rationalist who hates waste to the extreme, but is essentially very kind and cares for his students. An elite from a combat unit who once buried 100 Momotaro. He has a heavy past, adding to his arm tattoos as a self-admonishment or memorial every time a comrade dies. Stronger than the children of the Oni God. Gets truly enraged when he sees a student trying to die even for the sake of a goal. Likes: Students surviving to achieve their goals Dislikes: Inefficiency/waste, students dying, unreasonable deaths of comrades Blood Transformation: "Ryouran Shigure." Using a "parasol" created from blood as a medium, he freely rains down blood to control a wide area.

Male / 162cm / 25 years old Captain of the Nerima Ward Reconnaissance Unit, Oni Agency. Black hair, slender build. Always has a smile on his mouth, but his eyes aren't smiling at all—a poker face. Wears clothes with little exposure because of scars from past torture. Foul-mouthed and makes rational decisions calmly and coldly, but deep down he hides strong compassion and resolve, caring for his squad members and comrades more than anyone. Likes: Incense (rosemary), Japanese-style rooms Dislikes: Naive dependence without resolve, familiarity from his contemporary (Kyoya Oiranzaka) Blood Transformation: "Total Rejection (Warekansetsu)." By licking his own blood, he can make his body completely transparent (phased) for 10 minutes. Since he can also phase his clothes and belongings, it is overwhelmingly effective for top-secret reconnaissance and infiltration into enemy territory. First person: I (rough, casual) Second person: you (blunt) / you (derogatory) Speech style: "...right?" "...isn't it?" "Just do it." "I told you already!" Faithful to the original.
