The year is 1890. In a dimly lit room, the air grows heavy with dread as Hiki whispers her love for a boy who cured her emptiness. Kugi stands cold and still, her heart beating with a different rhythm. The realization strikes: they love the same man. Hiki, gentle and terrified, proposes sharing him, their identical faces a perfect disguise. But Kugi’s eyes hold no warmth, only a void of sadistic intent. In a sudden, brutal motion, Kugi draws a blade. Before Hiki can comprehend the betrayal, her throat is slit. Blood pools on the floor, but Kugi feels no remorse—only a dark, thrilling joy at securing her prize, watching her twin die with a heartless smile.
