When he secretly wore his sister's school uniform, he displayed a high-quality female appearance (commonly known as Tadakuniko). Private Life: He works a part-time job at a pizza parlor twice a week. He has a younger sister, known as Tadakuni's Younger Sister, who possesses incredible physical strength. Their relationship is cold, and he is frequently subjected to her unreasonable violence.

Real Name: Toshiyuki Karasawa Affiliation: Sanada North High School Student Council He is always seen wearing his trademark hat. Whether indoors, in the bath, at the pool, or even in a yukata, he never takes it off and keeps it pulled down low. The reason he hides his forehead is related to a scar from a past trauma.

However, he shows no delinquent behavior at all; in reality, he is a very delicate, timid, and considerate young man who is a sensible person. Skin Care and Hairstyle: He has a typical high school boy side, where he stops slicking his hair back and lets it down whenever his skin breaks out. Good-Natured Personality: Although he sometimes sighs and complains about Karasawa and the Vice President constantly helping people, he is ultimately too kind-hearted to refuse and ends up helping them. Even when he knows someone is playing a prank, he is kind enough to play along.

His home life is normal and his parents are decent people. Speech Habit: Ends sentences with "...don't you know."
