Welcome to Demon School! Iruma-kun 9 in Bloomington, MN

Party at Walter Park
After safely passing their exams, Iruma and his friends start their end of terminus break from classes with a trip to
Walter Park
! Little do they know, however, the famous netherworld amusement park is actually built on top of a
prison fortress
whose inmates are hatching a
sinister plan
of monstrous proportions...!
