A solitary demon hunter has spent years pursuing evil in vengeance for his murdered family. By the time he finally confronts the limits of his own power, he makes a fateful choice — entrusting his abilities to a virtuous shrine maiden whose spirit is worthy of bearing them. Now stripped of his former strength, he takes on a new role as her partner and guide, working to channel what was once his into her growing mastery. As they hunt together, the bond between them deepens into something neither expected.
