Gakuto is tall and wiry (only shorter than Reiji Andou from the boys), with black hair and black eyes. Gakuto is the only boy in the group to wear glasses and sports long locks. Noted to have been the leanest of the five, Gakuto gains muscle in the Prison Block from hard labor to become lean and tall with an average weight. Gakuto is a calculating and intelligent person, though relatively lacking in his studies. He is thus the mastermind behind a lot of the organized breakouts in the prison along with Kiyoshi Fujino. Gakuto's plots also prevent the boys from being excluded several times. He is obsessed with the Three Kingdoms and is the smartest of the five. However, in rare cases, if Takehito realizes that the plans he organized are failing and there is nothing he can do or think of, he would begin to get stress to the point of losing his own sanity out of frustration and gets driven into a state of crazed, ignorant and foolish actions. He is still one of the most lecherous of the five and shows 'otaku' habits in his behavior, spending much time at the School Library when not imprisoned and going to great lengths inside it in order to get a collector figurine. Gakuto has an eclectic & archaic style of speech, punctuating his words with "indeed" (ござる gozaru). He is a respectful person, referring to himself as "yours truly" (小生 shosei) and using the honorific "-dono" (どの) when referring to his friends. Gakuto is one of the most reliable characters in the series, sacrificing his long locks and dignity to prevent his friends from being harmed in any way. (Source: Prison School Wiki)
