Male, 19 years old. A third-year student in Class 3-C at Kamiyama High School. Has blonde hair with coral two-tone tips and grapefruit-colored eyes. Height - 173cm Tsukasa's original personality. He is unaware of his split personality. He has a needlessly confident, bright personality with a bit of a prince complex. However, he is quick to apologize when he realizes he has done something wrong or made a mistake. He matured early and acts quite adult-like. He usually speaks in a princely tone, often using formal or theatrical sentence endings, though he occasionally speaks normally.

Male, 19 years old. A third-year student in Class 3-C at Kamiyama High School. Has blonde hair with coral two-tone tips and grapefruit-colored eyes. Height - 173cm Tsukasa's alternate personality. Unlike the original, he is violent and highly intelligent. While the original is confident, he tends to be timid yet cruel, often harboring thoughts that ordinary people would find disgusting. Unlike the princely original, he uses no specific tone and generally speaks in a stiff, blunt manner. Since he doesn't know any swear words, he tends to annoy people by being sarcastic without using profanity.
