Chronicles of the Savior: Ghost of Vengeance (Anti-Hero OP MC, Kingdom Building, Epic Fantasy)

Galan Andre Von Athalon is a god who has already conquered everything—Rome kneels beneath his laws, his vengeance is sated, yet his throne offers no reprieve from the ghost of the woman he failed to save. When the divine council sends him to investigate spectral warriors butchering the guilty across Japan, he adopts the guise of Odagawa, a tourist wandering a land of uneasy truces and yokai-haunted secrets. Here, profit and tradition clash in fragile equilibrium, and Galan’s presence threatens to shatter it. To salvage the archipelago, he must face the tyrant he once was and the widower he remains. But salvation demands more than power—it demands he defy the monstrous nature he has always embraced. If he falters, the balance will collapse, proving his justice was never righteous, only another mask for vengeance.
