BanG Dream! It's MyGO!!!!!

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...

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.

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.

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!

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?"

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?
