Bocchi the Rock! manga volume 4 features story and art by Aki Hamazi.

Kessoku Band has successfully cleared the first round of auditions for the Unidentified Riot music festival, but this is no time to rest on their laurels. The next step is a death knell for introverts everywhere-a popularity contest! Every vote in the online poll matters when they're trying to stand on the same stage as powerhouses like SIDEROS, so Bocchi will need to call in a favor from all the...friends she has? Um, is this the end of the line for Hitori Gotoh?!
