Aiko Sekozawa is a second year at Karasuno who was gone for the last year, playing volleyball in another county to become better. Now that he's back, he better and ready to bring his team to nationals. It's a crappy description, but give the book a go. Also this will be second season of Haikyuu. And I don't own Haikyuu, obviously, although I do own my characters and any plots I might add.
