9-nine- Ruler's Crown - S01

While helping out at an anime convention to promote his city, high school student Kakeru Niimi gets caught in a sudden earthquake. During the emergency, he enters a shrine and sees a strange relic shatter. The next day, his classmate Miyako Kujou, who was cosplaying at the event, worries that the earthquake has cursed her, but Niimi brushes off her suspicions. However, Niimi changes his mind when he finds out that various people in the city have gained supernatural powers, and that some have started using them for wicked purposes. Luckily, Niimi is not alone: he is joined by Miyako, his sister Sora, and a cold girl named Noa Yuuki, who have all awakened to their own abilities. If the group wants to keep their hometown safe, they must work to prevent any future incidents while unraveling the mystery behind it all.
