When the alien Gitai invade, Keiji Kiriya is just one of the many raw recruits shoved into a suit of battle armor called a Jacket and sent out to kill. Keiji dies on the battlefield, only to find himself reborn each morning to fight and die again and again. While on his 158th iteration, he sees something different, something out of place: a female soldier. Is she the key to Keiji's escape, or to his final death?
