Plunderer

Every human inhabiting the world of Alcia is branded by a “Count” or a number written on their body. Depending on how each person lives their life, this Count either goes up or down. For Hina’s mother, her total drops to 0 and she’s pulled into the Abyss, never to be seen again. But her mother’s last words send Hina on a quest to find a legendary hero from the Waste War, the fabled Ace!
