I'm Gonna Annihilate This Land

Reincarnated as a powerless bald skeleton and subsequently betrayed by the gods who tricked him with a false promise of humanity, the most wicked and feared Demon King was sealed away for challenging the heavens. Centuries later, he awakens—not as a monster, but as a human infant revered as a holy saint. Armed with the memories of his past life, divine powers, and a burning grudge, the former Skeleton King infiltrates the very religious society that worships him. Posing as a pious saint, he plots his ultimate revenge: to make the deceptive gods choke on their own hubris and utterly annihilate this corrupt land.
