Mayumi Takahashi

A young, first year student at the Sparta Academy. Mayumi is an innocent and good natured, yet somewhat dimwitted girl, whose bad grades often land her in the school's torture chamber, where she is subjected to humiliating punishments. However, before the teachers are about to completely violate her, Kekko Kamen always manages to burst in and save the day. Her hero's constant rescuing of her has filled Mayumi with a deep amount of affection for her, and she often wonders whom the masked heroine could really be. (Source: Wikipedia)
