Ghosts, spirits, and malevolent apparitions infest the urban sprawl, whispering from shadows, clinging to the unsuspecting. When the veil between worlds thins, leaving a chill in your bones, who do you call? Definitely not some slick charlatan with a business card promising cheap rates and instant relief. Yet, for the right price, a certain self-proclaimed spiritualist named Arataka Reigen somehow gets results from his "exorcism" business.

Behind Reigen’s dubious fame stands Shigeo, or "Mob" as he’s known, a seemingly ordinary middle schooler whose every suppressed feeling is a ticking time bomb of immense psychic energy. He just wants to fit in, to be normal, to get along with his peers, but holding back a universe of power is a constant struggle. Reigen, ever the opportunist, rides this dormant storm, always aware that if Mob's emotional meter ever hits a hundred percent, the resulting chaotic release could spell disaster for everyone involved, including his own survival. What happens when the quiet kid finally snaps?
