I recommend "The Journey of the Ninja Puppet" to you. This is a light novel, a derivative Doujinshi novel. The main character became a puppet because he was addicted to spending money. But it didn't matter. He had a key to make himself beautiful and strong to help him. It was just that a puppet couldn't be a human. He could only be a puppet. I hope you like this fairy's recommendation. Muah ~😗
