A divine calamity has struck the heart of Tokyo.
Yukari Mizuki, a beautiful and powerful Kitsune, is stripped of her nine powerful tails and exiled to a fragile human form. Now powerless and hunted, her only hope lies in retrieving the tails, each held by a Yōkai, before the resulting chaos shatters the boundary between the spirit world and the human one.
Her reluctant aid, Hayato Ryūsei, is a skilled Onmyōji who was initially sworn to destroy her. But seeing the escalating destruction caused by the nine corrupted spirits, Hayato must put aside his hatred and become Yukari's shield.
Together, they embark on a quest across the hidden temples and neon streets of Japan, fighting to reclaim what was stolen.
But what secrets lie behind the fourth wall? Why was Yukari betrayed? Can they find the answers on Yakari's journey to be whole again?
