Okay, I think I know what's going on. You see, it must be some kind of a school festival thing, and that's why Kise, Murisakibara, and Akashi are dressed up (as ghosts). Kise decides to scare someone (probably Tetsuya). Tetsuya freaks out and Ignite Passes him in the face. ...Whatever Takao and the rest are doing I have no clue.
