From INKR: Shirogane Takeru, an ordinary Japanese teenager, was transported to an Earth under attack by alien creatures called BETA. Like any would-be hero, he volunteers to save the world, only to fail miserably in the attempt. Now he's stuck in a time loop, and forced to watch again and again as his friends die and he fails to complete his mission. After countless iterations, though, it's finally time for things to change.
