Yuuji excels in track and field, yet he finds running in loops uninteresting. Instead, he takes delight in being part of the Occult Research Club. What started as a mere hobby takes a dark turn when an actual spirit appears at their school. Things spiral into chaos at Sugisawa Town #3 High School when a cursed object unleashes terrifying creatures. In a bid to harness its power and save his peers, Yuuji consumes the object. This act leaves him cursed, plunging him into Megumi’s adrenaline-filled realm of exorcists and nefarious creatures.
