Bocchi the Rock! manga volume 6 features story and art by Aki Hamazi.

Hitori “Bocchi” Gotoh may dream of becoming a rock legend, but she and the rest of Kessoku Band have a long way to go before they can pay the bills with their musical skills alone—and graduation is approaching fast. Thoughts of the future can wait, however, as all the employees of Starry are pitching in to throw Seika a birthday concert over the holidays! The girls have played plenty of shows at this point, so surely the added task of planning and organizing the event can't be that hard, right?!
