9: Ruler's Crown

Synopsis

While helping out at an anime convention to promote his city, high school student Kakeru Niimi gets caught in an unexpected earthquake. During the chaos, he enters a shrine and sees a strange artifact shatter. The next day, his classmate Miyako Kujou—who had been cosplaying at the convention—worries that the quake has cursed her, but Niimi initially dismisses her concerns. His perspective changes when he notices that many people in the city have gained supernatural abilities—and some are already using their powers for harmful purposes. Luckily, Niimi is not alone; he joins forces with Miyako, his sister Sora, and a cold girl named Noa Yuuki, all of whom have also discovered their own newfound powers. Together, they must defend their hometown from further danger while solving the mystery behind these events.
