It seems that the person whose name is written in The Guess Note will act like a "Mess". If that's the case, it's time for the YSP Club. Jinpei and his colleagues decided to go to the library where Guess Note was said to have appeared first.

It's just Jinpei who got the game, but he can't use his superpowers, and it's a pretty bad game for the YSP club.
