Anon’s classmates encourage her to come with them to RiNG, a live venue with practice studios, to look for members for her band. She reluctantly agrees to go along and runs into the last person she wanted to see again.

Band rehearsals aren’t going well, making Taki more and more annoyed. RiNG’s stray cat, Rāna, appears to say she’ll “do the band,” but she leaves as unexpectedly as she arrived, increasing Taki’s frustration. Will they be ready in time for their concert?

After hearing from Soyo about the circumstances surrounding CRYCHIC's break up, Anon brings Tomori, Soyo, and Taki together at RiNG where she tells them to talk everything out!

Anon transfers into Haneoka Girls Academy late, just before Golden Week. She soon realizes that almost everyone at school is in a band and hurriedly begins building one of her own. She tries inviting Haneoka's quirky girl, Tomori, to join her, but...

The band forms around a certain promise, but Anon isn’t taking practice seriously even in the face of a rare opportunity for the group. Fed up, Taki says to Anon, "You're just running away, aren't you?"

Soyo's shock from playing Spring Sunlight without warning, and from seeing Sakiko's tears, has made her drop out of contact with everyone. Anon and Tomori are worried, but Taki says it doesn't matter. Elsewhere, Sakiko asks Uika to meet with her.

After successfully concluding their live performance, the members of MyGO!!!!! gather at RiNG for an after party. But not everyone is happy for them.

Soyo has always behaved as others wanted her to, even when she was very young, but CRYCHiC was the one thing that she held dear and she refuses to believe that it's finished. What will she do? And how will it affect the others?

Anon, Rāna, Soyo, and Taki were all deeply moved by Tomori's song. The matter is settled. Or at least, that's what they think. Then, they find out that they're scheduled to perform again. What will they do with only one song, no name, and no costumes?

Tomori is awkward, unable to fit in with those around her. In her third year of middle school, a blossom from a fragrant snowbell tree leads her to a chance encounter that changes everything.

Anon, Tomori, Taki, Rāna, and Soyo have finally come together again as a band. They've managed to finish their costumes, but they're still trying to pull things together right up until they go onstage. Is their new song really ready for an audience?

Even as the band rushes around to get ready, the day of their first live performance is upon them. None of them feel ready, but before they know it, it's time to go on. As Tomori stands on the stage, her legs trembling, the crowd grows restless.

The members of the band have all gone their separate ways. Tomori is having a hard time sorting through her feelings, so she goes to the planetarium where she happens to meet someone who helps her see a course of action she can take.
