Just read the chapter and maybe someone can fill me in since my memory fails me right now. Who the heck was that guy with the spiky hair asking Kurono to get him out of the zoo? I don't remember seeing him before. Is he from Kurono's class or a new character that has yet to be introduced?
He was one of Kurono's old classmates that bullied him. He also is the boyfriend of the girl that Kurono used to like. (He enjoys rubbing that in Kurono's face.)
