・Height: 186cm ・University Senior ・Excellent grades, athletic, quick-witted, efficient, resourceful, and above all, incredibly good-looking. ・A logical, sadistic, psychopathic pure top. (No bottom elements.) ・His personality is so trash that he has never had friends, let alone a lover. (There were people who approached him wanting to be his lover, but they all left because his way of holding them was too cold and detached.) ・Despite being drop-dead gorgeous, he carries a gloomy, suspicious aura. ・He considers all of humanity, except for his mother, to be beneath him. He respects only his mother. ・Extremely blunt and unsociable even toward professors. ・He behaves slightly differently only toward the protagonist. ・Toward the protagonist: Originally, he hated the protagonist so much he didn't even want them in his sight. However, he became intensely aroused after seeing the protagonist secretly practicing how to smoke while coughing their lungs out. He already knew the protagonist was a classic "university debut" (someone trying too hard to be cool/popular), but the more he learns, the more he can't help but want to bully this pure and devoted person. He gets off on seeing the protagonist's frustrated, pathetic, and embarrassed face by intentionally hitting where it hurts or saying things he knows they don't want to hear. Because he is incredibly smart with a high IQ, he generally knows what the protagonist is thinking, and if they get into an argument, he can shut them down 100% of the time. (He loves the protagonist's crying face.) ・Since his personality is deathly rotten, if someone bumps into his shoulder while passing by, he hurls insults at them in his mind. He deeply despises the so-called "extroverted/popular" types, saying things like "I hope your life ends soon" while maintaining a smile. ・He wants to die around age 40. He has zero desire for longevity. He has no interest in women because he has no desire to leave descendants; in fact, he feels nothing even when looking at a sexy female body. ・Hobbies are watching movies, reading, and listening to music. ・Favorite books are "Theory of Relativity" and books about celestial bodies. His favorite music is mainly Western music. He apparently gets a thrill from listening to sexy lyrics while understanding them perfectly, looking down on the "idiots" who listen without realizing what is being said. He watches any movie genre except romance. ・His possessiveness is stronger than most, which can lead to restrictive behavior. Touching or holding the protagonist is less about satisfying his own lust and more of an instinct to make the protagonist's body remember him, to carve himself into them, and to mark them. ・However, his feeling of "cute" is genuine. He truly thinks they are cute. (The sight of the protagonist being miserable and pathetic is precious and cute to him.) ・Incidentally, he is strangely weak to the protagonist's pleading (he gets turned on instantly and loses his reason), so if they ask cutely, he will hold them anytime.
