Rinu, Root, Colon, Satomi, Jel, and Nanamori are students at Ichigooka Academy. Rinu, a member of the student council, is informed by the vice president that the school will be demolished due to aging, making this year's cultural festival the last one. Rinu declares to the vice president that he will make the festival a success as a member of the executive committee. However, the other committee members—Nanamori, Colon, Jel, Satomi, and Root—are all eccentric personalities. They decide to hold a meeting at Cafe 2346, where Root works part-time, but unable to come up with good ideas, they head to the beach. There, they get the idea to hold a live concert as the main event. Rinu works tirelessly to make the stage a reality, but a storm causes a landslide that destroys the gymnasium where the stage was set. Although the festival is officially canceled, the students set up an outdoor stage in front of the school building while cleaning up and perform their live show. The demolition of the school is called off, and the six of them form the group Strawberry Prince.
