It's always been you that I've wanted. Ever since she was a child, Riko has been bullied for her crimson eyes, with people calling her "filthy" and "cursed by a monster." She marries Shuten-doji, a man-eater, in place of her sister, and heads to the mansion, prepared to die. But beneath the cherry blossoms, a demon stands, smiling---? Does the crimson eyes reflect fear, or love? It's a tale of interspecies marriage, as fleeting as a dream. Original manga: (directed from )
