Choujin Densetsu Urotsukidouji: Mirai Hen - Season 1

A quarter-century has passed since the global cataclysm. The arrival of the supreme deity known as the Overfiend caused the collapse of the human, demon, and beast realms into disorder. After pledging to be reborn in a century to remake his flawed creation, the Overfiend returned to slumber within his mother. This plan has now gone awry. The Overfiend has been born prematurely and now anticipates the arrival of his destined foe, the Lord of Chaos. His survival depends on Amano Jyaku and his sister Megumi. However, destiny has taken unforeseen turns, including the evolution of a new race of half-breed demon beasts. Amano journeys to the kingdom of Azuma to investigate signs of the Lord of Chaos, but becomes entangled in the expansionist plots of Caesar, Azuma's dictator. Amidst a revolt of enslaved demon beasts and the re-emergence of the sinister Munhihausen, only Amano and the demon beast Buju stand between the world and a second fiery annihilation. With the future of the planet at stake, all await the consequences of the Lord of Chaos's coming.
