At Private Tokiwa High School that thrives on club activities, there is a rule stating all students must be part of a club. Transfer students Kohinata Natsuko and Haruko managed to narrow their choices down to two clubs but are still unable to choose… Which club will you choose?

Private Tokiwa High School has a history of 80 years and has quite a history. "Accomplished in both literary and military arts" is their motto so students are required to not only work hard in their studies, but also club activities. Their education, sports and culture clubs are all at national level. After school, the grounds bustle with the voices of students practicing hard in club activities.
