Vitamin X

Seitei Gakuen is an elite Tokyo school running from kindergarten through college. Minami Yuuri is beginning her second year of teaching there and has finally been assigned to high school students — specifically to Class X, a group of seniors whose reputation is institutional legend. Every previous teacher assigned to them has ended their career early, citing ulcers or neurosis. Minami's job: reach this class and get them through college entrance.
