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 has a typically bizarre visit to her hometown over winter break, but even that weirdness isn’t enough to prepare her for what’s going on back at Midorigaoka Academy—someone is impersonating Super Bun to do evil deeds! Can the Public Morals club unmask the creepy doppelganger before Super Bun’s reputation is permanently destroyed?!
