About the book: 2024 / In search of power, I was unlucky to find myself in a place that can not be called anything other than the Underworld. Scorched earth, scorching scarlet sun and hordes of demonic spawn. How can an aristocrat expelled from his family survive in such a place? Certainly! Especially if he discovers the power to devour demons and thereby increase his strength. A hundred years later, I became the strongest creature in this world and was able to return to Earth, finding myself in the body of a half-dead teenager. A hopeless, at first glance, situation, but although... My power as a devourer is still with me, which means I will devour this entire world like the Underworld itself!
