異世界で聖女になったので国民的アイドルを目指します
A boy band idol named Kaiusagi Shirahase is in a car accident en route to a dome arena performance. The narrative shifts to a fantasy world where Coco Nina, on her way to a cathedral for a coming-of-age ceremony, is blessed by the Goddess with protective powers. At that moment, Coco experiences a sudden flood of unfamiliar memories. She realizes these memories are familiar to her—she recalls being Kaiusagi Shirahase.
