Why bother fighting spectral foes like all the other exorcists when you can just eat them?

Straight A student Eugene Korekishi doesn’t believe in ghosts…but his classmate Mogari Shishikuno is an exorcist who swallows them whole! Mogari can’t see ghosts on his own, but once he and Eugene meet someone with the sight, there’s only one path left—form an exorcist club at school and embark on a high school life that’s anything but a normal!

The school festival is coming up, and the Busters get a client request to form a band! Rehearsals are underway when Mogari is suddenly dragged back to Mount Shishikuno and forced to go through a grueling trial to best his bloodthirsty instructor. Tensions rise as Zaki, Koreshiki, and Tamon are left in distress about the fate of their friend… Will all four Phantom Busters be able to stand on stage together?!
