Mayu is a junior year high school student, but isn't like any normal one...seeing as she has a 'senpai' she tries her best to get his attention, but fails. She uses axes as a weapon to kill whoever gets in her way with senpai. She adores to wear lolita style clothing. Mayu's blonde hair fades to a rainbow, being the length to the back of her knees, when in 'Yandere' mode. Her hobbies are; Reading, playing games(pc/wii games, rpg type games, horror), and sometimes studying.
