Story Structure — 6 Plot Phases

Season 1: Club Formation

Yui searches for a new activity and is recruited into a threatened light music club. Ritsu and Mio form the initial musical core, while Yui's inexperience creates both comic difficulty and new energy.

Season 1: First Performances

The club gains an adviser, prepares for its first school festival, and confronts Mio's stage fright. Its first successful performance establishes music as a shared emotional project rather than a purely technical activity.

Season 1: Azusa's Arrival

Azusa joins and challenges the club's relaxed habits, forcing the older members to recognize their responsibilities. Family support and Yui's illness reveal that the club's bonds extend beyond rehearsals.

Season 2: Final Year Begins

The senior members begin their last year and worry about Azusa's future after graduation. The Kyoto trip and the younger students' sleepover contrast separation with continued friendship.

Season 2: Responsibility and Change

Future choices, exams, festivals, and performances make the end of school more tangible. Azusa becomes increasingly alert to the club's lack of preparation and the limited time remaining.

Season 2: Farewell and Memory

The club returns to serious preparation, performs at the final school festival, and records an album. Graduation transforms ordinary club memories into a lasting farewell for the seniors and Azusa.
