After a graduation show, Yuuta Hoshitani and his fellow second‑year classmates begin preparing for the upcoming Ayanagi Festival, which will be held in auditorium. For the first time, the event will take place without their Kao Council mentors, granting the students creative liberty to design costumes and scripts. Eager to share a stage together, the second years resolve to mount a collaborative production featuring music and choreography. The festival"s opening ceremony will double as the announcement of next year"s Kao Council nominees, a tradition that always draws crowds.
The Kao Council declares that Team Hiiragi has been chosen to perform at the opening, preventing them from joining the joint effort. This decision infuriates Hoshitani and his peers, deepening a rift between them and the Council. Determined to realize their dreams, the students hatch a plan to ensure that every second‑year can perform together on stage.
