Makai Kingdom: Chronicles of the Sacred Tome

"The story's protagonist is a self-proclaimed "Bad-ass Freakin' Overlord" named Lord Zetta, who attempts to prevent the destruction of his netherworld prophesized by Pram the Oracle. After discovering the Sacred Tome, Zetta finds a passage claiming that his own stupidity would be the downfall of his Netherworld. Infuriated, he burns the book, only to remember immediately afterwards that destroying the book would destroy his world. He quickly responds by confining his soul to the Sacred Tome and ventures to rewrite his world into existence by having the other Overlords of Netherworlds write wishes within his pages."
