You’re a student (or teacher) at Shujin Academy. You’re talking a shortcut to the school, when suddenly, your surroundings suddenly flash purple, before returning to normal.

You think nothing of it, blaming your poor sleep the night before. You round the corner to Shujin, finding in place a giant castle!? There are statues with the likeness of the schools PE teacher, Kamoshida. Just what is this place?

You see two people and a weird catlike creature talking before sprinting inside. One of them is in a black trench coat, the other in some kind of punk outfit.
