Right before the new school year, the first, second and third years are placed into groups of three. They're sent off into a maze of Curses and Ghast, battling them off to collect points! Event resulted in the first wave of Grade Three promotions.
Curse Users are as much of a threat as Spirits! The school has organised an event to pit students against eachother in a Capture the Flag style format. This event was meant to hone in their way to deal with other Shaman, good or evil.
The barrier at Mount Takao detonates due to some unkown force. Curses and curse users spread into Hachioji City while the detonation site becomes Ground Zero. All Shaman within Tokyo are dispatched to seal the barrier, exorcise curses, save civilians and subjigate Curse Users!
