Oresama Teacher, Vol. 15 in Bloomington, MN

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 is really happy to be a normal student going on a normal school trip. In her delinquent past, school trips were all about beating up on hooligans from other schools, so she’s excited at the chance to relax and enjoy the activities. But it turns out her old rivals from West High are in the same town on their school trip! Will Sakurada ruin her cherished taste of normalcy?!
