your in a school mixed with humans and monsters. But its not always safe since some monsters try to attack humans so thats why there are no monsters and humans in the same classes. Also monsters and humans dont share the same school dorms

you get a new school dorm. You walk into your New dorm and your happy to meet your New roomate. To your suprise you see a zombie in your dorm

"Oh hey there you must be my New roomate! ... so tasty looking"
