Chairman Kurihara Husbando

The Chairman (理事長 Rijichō⃝ℹ) is a supporting character of Prison School who works as the board chairman of Hachimitsu Academy. Notably, his first name is not known and his second name is not mentioned directly in the manga. He is the father of the female students Mari (a senior student and Underground Student Council President) and Chiyo (a first-year student).The Chairman is a grandiose and stern character who places emphasis on every ending word of his thoughts. He is a wealthy and influential man. He is a reasonable character who tries to judge the students fairly and unharshly, helping the boys; however, his sense of justice allows him to be manipulated by others. He is a compassionate person, as shown by his closeness to his daughter Mari in her childhood, his intervention on behalf of the boys and by filling a hole in the school wall with cement. Even so, he is an established pervert and is regularly shown watching porn or studying his original photo collection of South American women. He enjoys visiting South America and its beaches (the source of his collection), and has a fetish for women's asses over their breasts (pygophilia). In keeping with his authority and powerful aura in the school, his name has not actually been stated in the manga as his second name is implied from his daughters.
