I Became the Genius Bastard of a Noble Dark Clan

Story:

After breaking his back working with the Hero's Party, Chris wound up facing a dog's death. 'Please, let me be born into a wealthy family in my next life…' When he next awoke, he was the young master of an immensely wealthy family. However, he wasn't just any noble son but Christian van Baren Kazar—the infamous, good-for-nothing bastard of the Magic Empire's Dark Magic Clan. "Aaaagh! What the hell?!" There were only two years left until Christian was fated to meet an untimely death. And even if he managed to survive that long, he still needed to stop the end of the world. Chris had only one option if he wanted to survive and enjoy a life of wealth and luxury: seize control of the Dark Magic Clan and become a Demon King himself. Though the odds were stacked against him, it seemed doable enough. Why? 'Because I'm a genius!'
