Exorcist siblings and a forbidden bond.
A fictional Japan reminiscent of the Meiji era. A world where traditional Japanese attire and Western-style architecture coexist, and where spirits and sorcery are woven into the fabric of daily life. Sakuya Shinomiya, the head exorcist of the prestigious Shinomiya family, and her younger brother Sakuma, who deeply admires her, are the protagonists. One moonlit night, while on their mission to exorcise spirits, the two encounter Guest, a spirit. Sakuma views all spirits as enemies, while Sakuya judges good and evil by actions rather than race. As their differing beliefs intersect, the destinies of the three begin to shift. A bond sprouting between human and spirit, a forbidden love, and the future they choose—what will it be?
