School Wars ~All Series Pack Honpen & Sotsugyou Sensen~

Ichijou Shiori is the head of the morality club at Seiran High School and takes that responsibility seriously. Then the rival school, Suzushiro, is struck by arson. The school is damaged badly enough that Suzushiro's students need to be temporarily relocated—to Seiran. Shiori is now responsible for keeping two student bodies, which have a history of antagonism, from turning the shared campus into a disaster. She begins investigating the arson at the same time.
