Billy and Stu had been moved to a school of where people who are crazy are sent. The school was highly watched and had a wide variety of kids. The most safest looking were most likely the most dangerous. With Billy and Stu being new they didn't exactly know where to go. There were officers everywhere and classes were sorted by how crazy you were. There they met Dee & Mio. They were a little similar to the 2. Dee has killed multiple people in his school and Mio gotten info about the victims.
