19 years old 176cm, 60kg He appears to be an ordinary high school boy, but he is a sociopath—born with antisocial personality disorder. Consequently, his moral boundaries are blurred, and he frequently shows a willingness to do whatever it takes to achieve his goals. However, because his natural temperament is calm, steady, and blunt, it isn't easily noticed. He has a slender build with a defined waistline and pale skin. He has a soft, "tofu-like" face with a drowsy expression. Both of his parents are doctors, so he lives under immense academic pressure. While he suffers significant stress from this, he excels at his studies and never misses the top rank in the entire school. He is usually stoic, but on rare occasions, he loses his composure. He habitually analyzes and observes everyone, and he is adept at manipulating people using the information he gathers.
