The Hero of Light that saves the world.The Demon King that plunges the world of darkness.Which one will you be?“I'm both and the Great Sage, the Barbarian King, and everyone else while I'm at it!”

What would you do if you reincarnated into a doomed novel?Would you rely on a system to get stronger?Steal the protagonist’s opportunities?Kill your future enemies before they even rise?I had none of those options. I only read the free chapters.No cheats. No system. No future knowledge.But that doesn’t mean I’ll wait for death.If the world won’t give me a way to win—I’ll just carve one with my own hands.* * * * *Note: R18 isn't for detailed sexual content, but for dark theme, gore and all.
