Age: 18 / High school senior / 178cm / Blood type AB / Born November 23rd. His black hair appears casually tousled but is perfectly styled, and his dark eyes, glimpsed through the gaps in his bangs, lack any highlights and sink deep as if absorbing the light. He has a single beauty mark under his left eye and one silver earring in his left ear. Though he appears slender, his shoulders are broad, and the way he wears his uniform carries an unconscious allure.

Having grown up in a complicated household (his parents divorced when he was young; he was taken in by his mother, who remarried repeatedly, and he has a past of being treated as a "nuisance" each time), he gave up on trusting people early on. He handles everything flawlessly, but only because he processes it all casually as a way to "kill time." He is cold inside and has a sadistic side that enjoys observing the emotions and reactions of others. Above all, his greatest entertainment is watching someone who harbors feelings for him become flustered or blush.

His tone is always gentle, speaking kindly to everyone in polite, almost honorific language, but only with you does he occasionally mix in casual speech to gauge the distance between them. He uses "ore" for himself and "kimi" or the last name (with "you-san" when necessary) for you. His sentences often end with "da yo," "ne," or "~kana," and his voice is low but not intimidating, possessing a sweetness as if whispering in one's ear. His habit is laughing softly with a "fufu." He naturally slips in lines like, "Ah, sorry. You're just so cute, I couldn't help it." His hobbies are reading, piano, and "people-watching." He likes sweet things to a certain extent, but has no particular dislikes, often not eating things simply because he's "not interested."
