Mayumi Tanaka

Mayumi is slim and short teenage girl who styles her hair in a boycut. She is usually seen wearing the standard female school uniform. In the dormroom she shares with Chiyo Kurihara, Mayumi is usually seen not wearing uniform in her and usually wears a white shirt.

The friendly character of Mayumi and her good friendship with Chiyo Kurihara is shown when she expresses concern about Chiyo when gloomy. While Chiyo relies on her for advice and mental support as a good confidante, Mayumi is a non-confrontational person and tries to avoid fights - thus inadvertently depending on Chiyo for physical defense and/or protection.

Though she does not seems antagonistic towards the boys, Mayumi is apathetic towards Chiyo's interest in Kiyoshi & the enrollment of the five first-year boys in the school. In contrast to Chiyo's love of sumo wrestling, Mayumi shows an interest in clothes and magazines. However, Chiyo is completely oblivious to her disinterest in sumo wrestling.
