Yohane exists between worlds. By day, she's an ordinary high school girl living in a sleepy seaside town. By night, she transforms into a fallen angel detective solving supernatural mysteries that shimmer at the edge of reality. Her investigations pull her deeper into a strange mirror dimension where the impossible becomes routine: forgotten dreams take physical form, spirits linger in forgotten places, and music itself holds the power to reshape what is real. The line between her two lives grows thinner each case. Yohane gathers unlikely allies, each carrying their own connection to this fractured world. Together they chase answers about what the mirror dimension truly is and why Yohane can move between it and the human world. The mystery intensifies when she realizes something crucial: solving these cases might require her to choose which reality she actually belongs to. Part slice-of-life charm, part supernatural thriller, this film weaves together the complete story of how Yohane learned to embrace both sides of herself. For those drawn to magical girl narratives with real stakes and atmospheric mystery.
