God. Demon. Child. Blessed by the war god and partner to the immortal fox, fifteen-year-old Kono Takeshi loathes the sadistic woman who took him in after the brutal murder of his parents. His guardian seeks a tame pet, but he's the Kurogitsune-harbinger of death, and he won't be anyone's weapon. Still, a home means security, especially when he has a sister to think of. Then a stranger arrives in the backwater town of Shiranobe and throws Takeshi's uncertain future into turmoil. She believes he's good, despite the violence tainting his soul. But with an onmyoji determined to exorcise the Kurogitsune after him, Takeshi must weigh his broken humanity against its price in blood.
