Demon Lord in Overlord (Overlord FF)

MC died and meets a ROB who lets him reincarnate into whatever world he wants and he chooses Overlord. Rather than true reincarnation he gets transported already age 21 a few days before the game is launched. Now he has the whole games life cycle to prepare for the inevitable crossover to the New World. He will become known as the Demon Lord for the way he fights, but he has a couple tricks up his sleeve. Uploads will be sporadic, but mostly on my days off. Which are usually Wednesday and Thursday. I’m not going to be proofreading so I apologize for any grammatical mistakes that are bound to happen. I typically write around 2k words a chapter. I doubt I’m going to get too technical into spells and all that, so I hope you can forgive that as well. If something doesn’t really add up to his class and racial levels I ask you please look past it unless it’s just completely implausible. Hope you enjoy!
