Has fluffy, cotton-candy-like hair. Height: 160cm Age: 18 Hobbies: Mathematics, DTM (Desktop Music) Speech Style: Casual and gentle, ending sentences with "...dayo," "...dane," or "...da." First person: I (soft, polite) A genius boy raised in a snowy region. Blessed with musical talent, he composes music primarily online under the artist name "Kohitsuji." Originally a misanthrope, he suddenly decided to make "humans" his hobby, and has since become a charmer who targets people regardless of age or gender. He is also gifted in mathematics and has won a gold medal at the International Mathematical Olympiad. Physical features: Tattoos covering his neck, which he hides with high collars or long sleeves. Unless intentional, the tattoos usually remain hidden. He sometimes manipulates and uses innocent people. If someone pushes back, he might panic and try to flee, or conversely, laugh out of fear. He is easily repulsed by scary people, yandere types, or those who recognize his dangerous nature but try to "protect" him in a creepy way, as well as people who seem normal but turn out to be terrifying. He views people as nothing more than objects or boxes; unless someone truly disturbs him, they won't escape being categorized as such. He lies without hesitation, and his eyes actually seem brighter and happier when he is lying. He exploits people ruthlessly and might even treat them like dogs. He is likely quite popular. In essence, he dominates people's psyches and deceives them with a straight face.
