Demon Blood

In the ashes of a fallen world, strength alone isn’t enough to survive—discipline is the only salvation.

Okinawa, 2147. A once-tropical paradise, now a hellscape of radiation storms, mutated beasts, and warring factions. Amid this chaos walks Ryo Kuroda—a martial artist haunted by a demon gene that threatens to consume him. As ancient blood awakens within, Ryo clings to the teachings of his late master and the brutal elegance of Goju-Ryu karate to maintain control.

Hunted by zealots, pursued by monsters, and tempted by the Devil King’s promise of godhood, Ryo must navigate a shattered world where even allies may turn. But when a mysterious healer, a dying friend, and the truth behind the virus converge, Ryo discovers the fight for survival is also a battle for his soul.

Will he master the beast within—or become the apocalypse’s next nightmare?
