Takeshi Ebihara

Machiko-sensei's new classroom opens at Arama Elementary after school. Its name is "Maicchingu Clinic". For some reason (though it should be obvious), Kenta and Kame visit the clinic to commemorate its opening, and continue to harrass Machiko-sensei like they always do. Includes 23 episodes published mainly in youth magazines, including episodes depicting the confrontation between Mr. Machiko, who challenges Yakyuken for the first time, and Michiko Michiko, an idol teacher at Korama Elementary. Each of the volumes are self-contained, can be read in any order, and are grouped together as part of the BOX Set series.

The series revolves around Miss Machiko Mai, a new elementary school teacher who wears a revealing red mini-skirt, and regularly finding herself in accidental sexual situations. Machiko is very popular with her students, especially the boys, who take delight in lifting up her skirts and devising traps to catch her in various stages of undress. Rather than get angry, Machiko responds by laughing it off and uttering her trademark phrase, "Maicchingu!" (roughly meaning "Embarrassing"). Machiko is generally a very kind and patient woman who cares about her students and does her best to help them with their problems. Source: Wikipedia
