Overview
The Great Oni is an ancient and fearsome demon lord who rules the Shadow Realm with absolute authority. Born from the primordial chaos of the underworld, he was once sealed away by the ancient warriors of the human world after causing widespread destruction. Centuries later, his prison weakens, allowing him to return and reclaim dominion over both realms. With eyes like burning embers and a voice that echoes across dimensions, he commands legions of yokai and shadow creatures. Known for his devastating combat style and overwhelming aura, The Great Oni sees himself not as a villain, but as a necessary force of balance—destroying the weak to make way for the strong. His arrival heralds the end of peace and the beginning of eternal night.
