"Yuki, a fifteen-year-old girl, stands in the middle of a serene garden, yet the beauty of nature is overshadowed by the horror of the scene. Her silver hair flutters in the morning breeze, and her crimson eyes gleam with an eerie shine. Her white knife, adorned with a blue skull and a red rose, glistens with the blood of her four victims: two men in their fifties and thirties, and two women in their late teens and mid-twenties. The high camera angle reveals the details of the crime: blood splattered on the grass, bodies sprawled in various positions, and a mysterious smile playing on Yuki's lips. Everything indicates that this seemingly innocent girl has committed a heinous crime, the motive of which remains a mystery.
