Yuri Tama: From Third Wheel to Trifecta The Fifth

The good news: Yotsuba’s plan to unite her class in support of Yuna, Rinka, and Makina was a smashing success! The pervasive atmosphere of awkward discomfort that had been looming over her and her classmates is gone, and everyone’s finally ready to buckle down and make sure that their cultural festival idol show turns out as well as it possibly can! The bad news: A whole new problem for Yotsuba to stress over almost immediately rears its head! Mio Kuruma, Shooting Star’s second-in-command, bursts onto the scene in a desperate attempt to drag Makina back into show business! Worse still, she pulls Yotsuba into her scheme! How will Yotsuba contribute to the cultural festival, keep Mio from causing too much trouble, and resolve the ever so slight issue of Makina’s totally unaddressed feelings for her all at once?!
