Twenty-five years ago, the world was annihilated. With the coming of the Overfiend, God of all Gods, the human, demon, and beast realms collapsed together in chaos. With the promise that he would be born in 100 years to re-create his failed world, the Overfiend settled back to sleep within his mother's womb. But something has gone terribly wrong... Now the Overfiend is born prematurely and awaits the coming of his natural the enemy, the Lord of Chaos. His only hope for survival are Amano Jyaku and his sister Megumi. But destiny has moved in ways that even the Overfiend could never predict, as a new race of half-breed demon beasts has evolved. As Amano travels to the kingdom of Azuma to investigate the appearance of the Lord of Chaos, he is swept up in the world-conquering schemes of Caesar, Azuma's dictator. Against the backdrop of a demon beast slave revolt and the return of the diabolical Munhihausen, only Amano and the demon beast Buju can save the world from another fiery destruction. With the fate of the earth and its inhabitants hanging in the balance, all wait to see what the coming of the Lord of Chaos will bring...
