Takechi serves as the strategist of the Kiheitai, does not participate in much physical fighting. He is a self-proclaimed feminist, which he claims is the reason for his gentle treatment of women and children. Matako instead believes that he has a Lolita complex (and as such is a 'lolicon'). Takechi once commented that Kagura would be in her prime in a few years. He prevented Matako from killing Kagura, citing that her fighting ability would be incredible in a few years. He is heavily wounded by a crazed Okada, his fate after which is unknown.
His name is based on the Meiji restoration era samurai, Takechi Hanpeita.
