Monmon Retsusai

Monmon Retsusai, known as Miss Wriggle in the English dub, is the poetry teacher (national/Japanese language teacher in Japan) at Mochinoki Middle School.

Monmon Retsusai is the "secret weapon" Mr. Touyama brings to his history class when he tries to fail Kiyo as part of his revenge. All of the male students besides Kiyo became infatuated with Monmon's cute appearance, sexy voice and large breasts. Even though she is considered to be Mr. Touyama's "secret weapon," Monmon doesn't like Touyama even though she likes seeing him "love sick" over her (or "agony" in Japan).

Monmon Retsusai brings Gash and Umagon to class as her music assistance when she sings her song "Mon Mon" (known as "Love Sick Dance" in the English dub). While everyone is dancing to the song, Kiyo doesn't dance to it at all.
