Renka works late nights in Tokyo just trying to keep her life together, until a faceless spirit steps out of a dark alley and shatters everything she thought was real. Moments before she’s taken, a man with silver hair and burning eyes appears and destroys the creature with a single strike. He calls himself Yue, a guardian who has been watching her since childhood, and claims her family died protecting a secret tied to the spirit world. With the city she thought she knew cracking open around her and more yokai rising from the shadows, Renka is forced into a world of shrine magic, forgotten vows, and a bond she doesn’t remember—but her soul does. She may not understand her destiny yet, but she refuses to run from it. And as the veil between worlds trembles, both Renka and Yue must face the truth: fate didn’t bring them back together to protect the world. It came to test whether they are strong enough to change it.
