Okay, now we're back at the school. It's time for the boys to get their homework assignments done. The first assignment is to figure out the identity of the guy who's been living in Japan for the past few years. They're not sure if he's from class D or class B, so they're going to have to ask him. He's got a new nickname: "Tsubaki" , which means "treachery" in Japanese. The boys are psyched to get to the point, but they'll have to wait until the next assignment is done before they can get started. First, though, the boys have to get the homework assignments out of the way so they can talk to Tsubaki about his life in Japan. He doesn't want to get into a fight with anyone, so he'll ask him about his friend Shiraishi. He wants to know why he can't find out who he really is. He also wants to find out what's going on with the school fire. He figures out that it's because the school's old building is on fire, and that the fire is probably caused by the fire's source: the old school kitchen. He thinks that this will be proof of his friendship with Shuriishi, and he wants her to tell him all about her.
