The World Where We Exist
Saya saves Kai and Lewis from the chiroptera, but collapses afterwards. They take her back to Gray's house to recover. David learns Saya is at the farm, but doesn't react. When Monique touches the sleeping Saya, Saya pops her awake and almost attacks her. She barely acknowledges Kai's presence and calls Hagi to leave. Gray won't let her leave while she's still weak, though, and manages to get her to stay for breakfast. Kai tells her about David, but she cuts him off telling him it isn't relevant to her and that he should go back to Okinawa. Hagi finds David throwing up behind a building and asks if he's given up fighting. While they talk, a chiropteran attacks the farm, having followed Saya's scent. It gets upstairs and goes after Monique. Kai shoots it but is knocked aside. David also shoots at it, but is attacked. Saya, unable to find her sword, attacks it with a kitchen knife coated in her blood and kills it, then leaves with Hagi. As they walk through London, they spot an advertisement for a performance by Diva, who has changed her appearance to look similar to Riku. David and Kai also see the ad on TV.
