Chōei lost his parents and older brother in the World War II of Saipan; he now runs a parts shop in Okinawa. Frieda-Jane, a sergeant major, was born to an American father and a Philipine mother. Taka, a drummer in a rock band, was abandoned by his father for a life on the mainland and lost his mother to suicide. And the Vietnamese-born Annan is Chōei’s childhood friend from Saipan.
