George Miyagusuku

George Miyagusuku (宮城ジョージ Miyagusuku Jōji) was an Okinawan-American US Army veteran and the adoptive father of Kai, Riku and Saya.

Plot
George served in the Vietnam War as part of the US Army. He is one of the soldiers present when Saya goes insane in Vietnam, killing friends and enemies alike. One of the few survivors, he was 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 was inspired to live by the sound of Saya's heart beating in her cocoon.

When Saya 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.

While protecting Saya, he was attacked by a chiropteran. During his recovery from 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, though, 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.
