The Gray Exorcist

After his parents were murdered by the shadowy entities known as "kuragari," Sabatora joined the Public Security Bureau as an onmyouji, driven by a singular desire for vengeance. Despite his mission, he shares a deep bond with Kyue, a kuragari who has been by his side since childhood. To Sabatora, Kyue is not a monster but a gentle soul and a cherished member of his family. This fragile peace is shattered when Seto, a colleague within the Bureau who harbors intense hatred for kuragari, attacks Kyue. Forced into an impossible situation, Sabatora and Kyue undergo an unexpected transformation that changes their fate forever.
