He awakens in a blood-soaked alley filled with the gruesome remnants of dismembered bodies. Before him stands Tokisaki Kurumi, still covered in fresh blood from a recent act, offering him a sweet smile. Potential heroines mentioned include Kurumi, Oshino Shinobu, Military Princess, Kamado Nezuko, Ereshkigal, and Leticia, among others.
