Morokuzu, Takehito

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.

During the escape plan arc, he defecated his pants while in computer class, thus ruining his reputation with the girls.

He and Kiyoshi were also believed to be lovers for a large portion of the "escape" arc due to a series of misunderstandings.

He was originally shown with past shoulder-length hair, but in episode four of the anime (chapter 21 of the manga) he gets his head shaven as punishment for pulling down the skirt of the student council's president. Though, later, it was found out he did this on purpose for a wig that Kiyoshi will later wear to escape the prison.
