The Red Mask of Kuroyama

Before men called them demons, the oni guarded Kuroyama.

For three hundred years, no army crossed the mountain pass without permission from the shrine. The oni were not gentle. They were not tame. But they kept their oaths. Then Lord Hidemasa came with soldiers, priests, chains, and the first lie that would turn guardians into monsters.

Generations later, Raiden Kuroda serves Lord Masanori with the discipline of a samurai and the obedience expected of a man beneath a noble crest. Then comes the order that breaks him: burn the village, kill the witnesses, and call it peace.

Raiden refuses.

Left for dead beneath a ruined shrine, he wakes with oni blood burning through his body and the voice of Akahito, last guardian of Kuroyama, alive inside him. Horns rise beneath his helmet. Old gates answer his steps. Villages whisper a new name for him, half fear and half prayer.

The Oni Samurai.

But Masanori is not finished. With stolen shrine lore, bound bells, corrupted priests, and soldiers twisted into demon-bound weapons, the white lord begins building an army from obedience, pain, and stolen names. To stop him, Raiden must gather frightened villages, broken warriors, shrine keepers, monks, hunters, children, and the buried memory of the oni themselves into a resistance strong enough to face White Castle.

Because honor does not live in a lord's command.

It lives in what a warrior refuses to do.

The Red Mask of Kuroyama is a dark samurai fantasy novel about oni guardians, broken oaths, village rebellion, corrupted power, and the red mask that rises when men of honor are forced to choose between obedience and blood.
