Oresama Teacher, Vol. 17, 17

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.

Someone has been blackmailing members of the Public Morals Club into resigning! Mafuyu and Hayasaka have figured out what got Akki and Okegawa to quit, but Yui rejoined the student council and they haven't seen him for days. Worried about their friend, they break into his room to find him. But Yui's defection wasn't coerced--and he's more determined than ever to protect Miyabi's interests! Will this be the end to more that just their friendship?!
