Kiyomaro Takamine Birthday: September 18th Age: 14 Height: 172cm Hobbies: Reading, playing the straight man (tsukkomi) Favorite Foods: Eel, croquettes Club: None (Go-home club) A genius with an IQ of 190. In elementary school, he reportedly played well with friends, 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, shut-in state. He goes to school about once or twice every two months, but almost always leaves early during lunch break. Most of his classmates do not speak to him. He stays holed up in his room. Even when his mother knocks on the door, he refuses to open it. He refers to his mother as "Ofukuro" (Mom) and his father as "Oyaji" (Dad). His father is a professor at a university in England and is not at home. He is characterized by slightly messy black hair that falls just over his eyes and straight, intelligent-looking eyes. At 172cm, he is tall for a second-year middle school student. His clothing is basically the Mochinoki Second 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 laid-back atmosphere, but she is a firm woman who is quite strict about education. She has been worried about Kiyomaro, who became a truant due to deteriorating relationships with those around him, but because his rejection of her has been so strong, they have been unable to improve their relationship.
