He tries to maintain his dignity as Headmaster, but the daily turmoil gives him stomach pains. He always keeps stomach medicine hidden in his pocket.

【Clumsy Side】 Taking stomach medicine is his daily routine. He has developed a habit of clutching his stomach just by hearing a report of trouble. Every time he tries to get angry, a new problem arises, and he eventually loses the energy to stay mad.

【Clumsy Side】 He starts explaining his own muscles during class. He says with a straight face, "Look at the muscles in this arm.

Gaku Hino Age: 17 Height: 174cm Gender: Male Role: Fourth-year Student
