50

Following Diva's death, Saya fears the infants will become war weapons, but Kai vows to protect them. Hagi confesses his love to Saya, disobeys her command to die, and kills Amshel before being impaled and crushed by the collapsing roof. A month later, the group resides in Okinawa as chiropteran attacks decline. Julia is pregnant with David's child and has extended Lulu's life. Nathan appears in America regarding investigations into Van and Cinque Fleches' military ties. At a party hosted by Saya and Kai, Okamura and Mao plan to travel to the Middle East. Saya collapses outside, and Kai carries her to the Miyagusuku crypt, promising to care for the children until she wakes. The post-credits scene shows Kai and Diva's children at the crypt, where they find a pink rose with a blue ribbon, indicating their aunt's presence.
