Main Article: Gunparade Orchestra
Gunparade March focuses on the 108th Guard Squad stationed in Japan. The students here are poorly trained, inexperienced and would have no hope of holding their ground in a real combat situation. A girl named Hiroshi Ishizuka from one of the more elite units is sent to join the 108th. She must help these ‘rejects’ become an effective fighting force if they ever hope of surviving the war against the Phantom Beasts.
