Akane Motomiya is a spirited 15-year-old high school freshman from modern-day Kyoto who is thrust into a parallel realm known as Kyō, which mirrors the Heian period. There, she is recognized as the Priestess of the Dragon God (Ryuujin no Miko), destined to save the land from the demonic Oni Clan and the vengeful spirits they unleash. She wields the power to purify impurities, often through physical contact, and can commune with the divine Ryuujin while harnessing the five elemental forces. Her path requires uniting the Eight Guardians (Hachiyō), eight devoted men sworn to protect her. Though her innate kindness and naivety sometimes lead her into danger, Akane’s unwavering resolve, fierce loyalty to justice, and deep compassion drive her to confront Kyō’s threats. Initially overwhelmed by her destiny, she gradually embraces her duty, balancing her youthful innocence with the weight of her sacred role.
