In a near‑future colony war, a space station is attacked by terrorists. A young girl is rescued by a boy, but her parents are killed in the raid. Years later she enrolls in her grandfather’s military academy, where she meets a young man who bears a striking resemblance to the boy who once saved her. Just as she is about to enter the school compound, she spots a “terrorist” nearby, a member of a terrorist demonstration organized by the school’s command, launching the story into motion.
