One day, Kaiusagi Shirahase, an idol in a popular boy band, is involved in a car accident on his way to a show at the dome arena. The scene changes to a medieval fantasy world. The heroine "Coco Nina" is on her way to the cathedral for her coming-of-age ceremony. Coco is ecstatic as she receives the blessings of the Goddess with the power to protect this world. However, that was when an unfamiliar memory rushes into her mind. I know this… I know this memory… I… I am Kaiusagi Shiranase! (Source: COMIC Isekai Harem, translated)
