High school student Kakeru Niimi is assisting at an anime convention to promote his city when a sudden earthquake strikes. Amid the chaos, he takes refuge in a shrine and witnesses a strange relic shatter. The following day, his classmate Miyako Kujou, who had been cosplaying at the event, fears she has been cursed due to the earthquake, but Niimi dismisses her concerns. However, Niimi’s perspective shifts when he learns that various individuals in the city have acquired supernatural powers—and that some are exploiting them for malicious ends. Fortunately, Niimi is not alone: he is joined by Miyako, his sister Sora, and a aloof girl named Noa Yuuki, who have all awakened to their own abilities. To keep their hometown safe, the group must work to prevent further incidents while uncovering the mystery behind these events.
