A high school student named Nozomi crosses into Kyou, a mystical realm locked in the throes of civil war. The Minamoto and Taira clans clash for control while supernatural forces tip the balance: vengeful spirits poison the land's spiritual core, weakening the very gods who sustain it. She discovers her mysterious benefactor is Hakuryuu, a white dragon deity reduced to human form by these dark energies. As his priestess, Nozomi becomes bound to the conflict. Her role isn't simply to fight for the Minamoto, but to purify the corrupted spirits and restore Hakuryuu's strength. Only then can she return home. Caught between two worlds and two warring powers, she must navigate ancient politics, supernatural threats, and her growing connection to a god who desperately needs her help. The line between savior and pawn blurs as she discovers what she's truly capable of. One day spent in Kyou might change everything.
