"What's going on? Could this be... reincarnation?" I was left speechless as I stared at the reflection of a sinister-looking boy in the full-length mirror. He was the spitting image of Cain, the pitiful villainous noble from the game Apocalypse, who gets his fiancée stolen and is ultimately killed by the hero, Abel. To make matters worse, the fiancée stolen by the hero is none other than Selvia, my favorite heroine from the game! Damn it! If things continue like this, my beloved heroine will be taken away by that playboy hero, and I'll end up dead. No way am I letting that happen. Determined, I resolved to smash the game's scenario and carve out a future where Selvia and I could find happiness together. "If anyone can pull this off, it's me—the one who's mastered every inch of this game!" This is the story of a protagonist who reincarnates as a lazy villainous noble but, through the combination of his game knowledge and excessive effort, unknowingly surpasses the hero to become a legend in his own right.
