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. Mafuyu and the Public Morals Club are trying to investigate the Beast of Kiyama High, but his super strength and advanced disguise skills have them flummoxed. Even Shinobu’s feats of nighttime ninja prowess only serve to get him captured by the Beast. And back on home turf, Mafuyu finds herself inexplicably spending more time with their weird new homeroom teacher. He’s a mystery waiting to be cracked, but will the accidents that dog his footsteps crack her first?
