Eiji is a hybrid with a human astronaut for a father and a Gradosian noblewoman for a mother. He grew up as a low-ranking Gradosian SPT pilot on the Empire's homeworld. A pacifist by nature, he still decides to take a more direct hand when he learns of the invasion of Earth. Unfortunately he is torn between his beliefs and his loyalties towards the comrades of his homeworld, many whom he considers to be his kindred. This forces Eiji to go to extreme lengths to not kill his opponents: an ideal made vastly difficult by the amoral AI aboard the Layzner.
