The elderly administrative head of Sanada North High School assumed his role three years before the series’ events, overseeing daily operations with a stocky frame and weathered features marked by a prominent nose, thick grey eyebrows, and deep wrinkles. His receding grey hair clings to the sides of his scalp, interrupted by sparse strands above. He dresses formally in a white shirt, grey pants, and green tie, often layered with a light brown sleeveless jacket. Known for projecting an approachable demeanor, he actively supports students yet tactically employs fabricated narratives when lacking answers. This habit surfaces when questioned by the main trio and Karasawa about the school’s enigmatic "70-hour fast" tradition. Unaware of its origins, he invents a tale linking the ritual to the school’s 1984 founding, describing a financial crisis miraculously resolved through collective fasting. Students later uncover the institution’s true 1989 establishment date, exposing his deception. Beyond administrative duties, he fulfills ceremonial roles, including delivering graduation speeches in the anime. Though appearing infrequently, his capacity for persuasive falsehoods remains noted among peers and pupils, cementing his reputation as a pragmatic yet unreliable custodian of the school’s history.
