George Miyagusuku

An Okinawan-American US Army veteran who served in the Vietnam War, George is one of the soldiers present when Saya goes insane in Vietnam, killing friends and enemies alike. One of the few survivors, he is asked by the first David to watch over Saya's sleeping body after she falls into another hibernation cycle. He lost his wife and biological children in an accident years before, but is inspired to live by the sound of Saya's heart beating in her cocoon. When she wakes up from her sleep and he sees she is no longer a threat, he adopts her as his daughter. By this time, he also has two adopted sons, Kai and Riku, and he runs a restaurant-bar called Oboro, in Okinawa.

While protecting Saya, he is attacked by a chiropteran. While recovering from his wounds, he is kidnapped from the hospital and taken to a US military base where he is infused with Delta 67. After escaping, he is again wounded by a chiropteran while protecting Saya. The Delta 67 and the wounds from the chiropteran begin to change him into a chiropteran, so he asks Saya to pour her blood into his wounds and kill him. Saya is very reluctant, because he is the only father she has ever known. While they talk, he holds her hands, causing her blood to slowly run down his arms to drip into his wounds and kill him.
