In a realm plagued by menacing supernatural entities, even the most potent spiritual abilities can't mend every dilemma. Enter Reigen Arataka, a fraudulent exorcist devoid of any mystical prowess, yet proficient in running his ghost-expelling enterprise. His latest recruit? Tome Kurata, an enthusiast of the peculiar and enigmatic, and the school peer of Reigen's apprentice, Shigeo 'Mob' Kageyama. While Mob's extraordinary psychic might has solved countless cases for Reigen, Tome appears powerless beside her employer. However, under Reigen's tutelage, Tome learns that true power lies in self-assurance and faith, proving that belief and confidence can wield influence, even in the absence of supernatural gifts.
