Takeuchi

A minor character in the Baka to Test to Shoukanjuu series. She is a Modern Japanese teacher in Fumizuki Academy. In the anime adaptation, as Akihisa Yoshii, Minami Shimada, and Mizuki Himeji are trying to escape from the raging Miharu Shimizu, they ask for her supervision approval for a Shoukanjuu Battle because it's the weekend and there is no other teacher in the vicinity. She's one of the three female teachers introduced in the series, although her appearance in the anime was short.
