When aliens known as Mimics invade Earth, Keiji Kiriya is just one of many recruits who don a special exoskeleton combat suit and are sent out to kill. Keiji dies on the battlefield, but to his surprise, he wakes up and relives the same day, fighting and dying over and over again. Stuck in this loop, he gradually improves his skills and tries to understand what is happening to him in order to change his fate.
