- Description from novelbuddy

Our protagonist Caam is a man from Earth that was reincarnated into this world as a demon. In order to survive, he spared no effort in avoiding the sparks of battle and without noticing it, he became strong himself.

Aether Moirai was never meant to be free.Born from the final spark of the Abyss—a forgotten god’s last act of rebellion—he is the last vessel, a boy whose powers grow stronger the more his mind fractures. Bound by the Codex, a system that can rewrite history itself, Aether is hunted by worlds that fear what he might become.The Infinite Library has always been his home—a labyrinth between worlds where every book is a living realm, and every story is a battlefield. But when the tales begin to warp, birthing monsters and rewriting entire histories, even the Library’s endless shelves can’t protect him.To survive, Aether must step into dangerous books where myths breathe, legends bleed, and the wrong choice can erase you from existence. Each journey brings him closer to the truth of his creation—and the author who penned his fate.He is not the hero of these stories.He is the flaw in every one of them.
