Ah, the cultural festival. An annual tradition with a long history of being an absolute nightmare for the loner. Hachiman is ready and willing to run at the first sign of responsibility--but while he's busy skipping festival prep in homeroom, he is chosen as a reluctant tribute to the schoolwide festival committee instead! Meanwhile, Yukino is saddled with unwanted tasks of her own, but the lingering tension between the members of the Service Club makes it difficult to intervene. To make matters worse, her big sister Haruno just can't leave well enough alone.
