Four Demon Queens Want Me

Ex-fire captain tames four monster queens to save humanity's last enclave.

After losing his command, a former FDNY captain is drafted into a lethal nightmare game. A bloodline system grants him the power to subjugate four S-rank monster queens, turning apex predators into loyal pillars of a fledgling regime. Their combined might pushes back the encroaching Void Lord, expanding America's final protected enclave, while their union produces godlike offspring destined for the coming war.
