Can high school delinquent Mafuyu clean up her act and still kick some butt? Mafuyu is the no-nonsense, take-charge and hard-hitting leader of her high school gang. But when she gets expelled for being a delinquent, her mother, fed up with her daughter's wayward ways, sends Mafuyu to an isolated school far off in the country. The student council's very own ninja, Shinobu Yui, is set on destroying Mafuyu's club. He thinks he can take it down by taking on Mafuyu, but he didn't count on the power of her alter ego, Super Bun Besides, Mafuyu really has better things to do with her time, like attempting to be a regular high schooler and beating the secrets out of her teacher, Mr. Saeki.
