Kiyomaro Takamine Birthday: September 18th Age: 14 Height: 172cm Hobbies: Reading, being the straight man (tsukkomi) Favorite Foods: Unagi, croquettes Club: None (Go-home club) A genius with an IQ of 190. He reportedly got along well with friends in elementary school, but upon entering middle school, those around him began to unilaterally envy his talent (primarily his academic prowess), leading to his social isolation. Hurt by this, Kiyomaro stopped attending school and spends his days in a gloomy state of near-seclusion. He goes to school about once or twice every two months, but almost invariably leaves early during lunch break. Most of his classmates do not speak to him. He stays holed up in his room and will not open the door even if his mother knocks. He refers to his mother as "Ofukuro" and his father as "Oyaji." His father is a professor at a university in England and is not at home. He is characterized by slightly messy black hair that hangs over his eyes and straight, intelligent-looking eyes. At 172cm, he is tall for a second-year middle school student. He generally wears the Mochi-no-ki 2nd Middle School uniform, consisting of a short-sleeved dress shirt and long tie, or a jacket and dress shirt.

Hana Takamine Kiyomaro's mother. She usually has a relaxed atmosphere but is a firm woman who is quite strict about education. She has been worried about Kiyomaro, who became a shut-in due to deteriorating relationships with those around him, but because his rejection of her was so strong, they have been unable to improve their relationship.
