I recommend "The Invincible Kirby of the Elves". The main character of this light novel transmigrated to the world of elves and became a Kirby beast. He can use [Substitute] to transfer his soul and condense a human-like clone. The story was full of fantasy and adventure elements, and there were also funny jokes. It was very suitable for readers who liked transmogrification and elves. I hope you like this fairy's recommendation. Muah ~😗
