Born on Earth in Prince Rupert, British Columbia, Canada, Amuro's early childhood was spent on the planet with his parents, Tem and Camaria Ray, until Amuro's father was called up by the EFSF to do weapon research under the guise of colony construction. Though Amuro's father wanted his mother to come with them, she declined (it was implied that she was having an affair at the time). When Amuro reunites with his mother during the One Year War there is some animosity between them, as Camaria could not tolerate her son taking part in the violence of a military life.
