This is the latest VIZ Media LLC installment by Hiroshi Sakurazaka.
According to the product description:
“There’s one thing worse than dying. It’s coming back to do it again and again…When the alien Gitai invade, Keiji Kiriya is just one of many raw recruits shoved into a suit of battle armor and sent out to kill. Keiji dies on the battlefield, only to find himself reborn each morning to fight and die again and again. On the 158th iteration though, he sees something different, something out of place: the female soldier known as the Bitch of War. Is the Bitch the key to Keiji’s escape, or to his final death?”The author bio notes: “Hiroshi Sakurazaka was born in 1970.
