Cleo, a middle aged man, as rich as you can get, envied by many, and hated by more was murdered for unknown reasons. He thought it would be the end, and yet he awakens in a foreign body. Now in a new world, he comes to understand that he's a Nestler. They are special beings who can create their own nest and make monsters to do their bidding.

Inspired by Lair. Note : I'll try to work hard on the MC character so if you find some strange things about him, it's normal. Also I'll add more tags in the future as we get there.
