The Unorthodox Genius of the House of Darkness

The world has ended. I was a genius hero, but my efforts were too little, too late—I couldn’t stop the Blood Demon Emperor. As I died, I prayed for a second chance... but this isn't what I meant! Of all people, I’ve become Christian, a rogue member of the House of Dark Demons. As if that wasn’t enough, the world is still ending in just five years. There's only one way to save it: I must become the emperor myself and stop the war! I know it sounds ridiculous, but I’m a genius—I can make it work!(Source: Tapas)
