Back at the beginning of the chapter, we're introduced to a new character named "Sankashi" . He's a super-nice guy who's super-smart and super-kind of a jerk. We're also introduced to "Clack" , who is super-annoyed by the fact that "Aoyama" is going to be in the next room instead of the one he's in right now. Clack wants to know what's going on. He wants to apologize to Sankashi for what he said back in Chapter 1 , and he wants to play soccer with him again. He also wants to ask how he got the keys to the other rooms in the room. He doesn't know how to get them from the other room, so he asks Clack to tell him how to do it himself. This is the first time Clack's ever been in a room like this, and Clack is totally confused. He asks if he can just get one key from the guy in front of him, but Clack won't give him one. He tells him to leave the guy out of the way, and then they start talking about how they're going to get back to normal.
