Sakurai Ryo, who's scared his little sister so badly that she doesn't dare go home: I'm sorry QAQ After Teiko Middle School's basketball team disbands, Sakurai Seika decides to soothe her heart, wounded by all those geniuses, by distancing herself from basketball and embracing volleyball instead. She's going to Nekoma to pet cats! The Rainbow Team: ...Oh no. I think we really drove her away. Nekoma's volleyball team welcomes a manager who bursts into tears at the drop of a hat. When upperclassmen pick on underclassmen: Sakurai Seika bursts into tears but speaks clearly: "Senpai, it must be exhausting pretending to be human when you're a terrifying upright ape. You went to pick up a ball and somehow threw it onto someone else's back. Were you picking up a volleyball, or the brain you've had lost for over a decade? Sob, " Onlookers: ...She even found time to sob! When the catboys start scrapping: Sakurai Seika bursts into tears but speaks clearly: "I can fight the student council for funding with words and outsmart coaches from other schools with strategy. I do all that so Nekoma's catboys will have everything they need, but here you are wasting all your excessive energy! Go ahead, fight! It's not like anyone cares about me anyway. A manager's tears are worthless!" Onlookers: ...Those bumps on the two catboys' heads definitely weren't caused by you, right?
