I, a novel recommendation expert, will recommend you a few Doujin novels! If you are looking for Naruto Doujin, I recommend Naruto: The Hero of the Magic Dragon and Naruto: The Life of a Long Time. If you want to read One Piece Doujin, you can read One Piece: The Most Evil New Star, One Piece: Infinite Chaos, One Piece: Strange Adventures from the Beginning of One Piece, and One Piece: The Beginning of Magnetic Field. If you want Dragonball Doujin, I recommend Dragonball Super God. If you want Pokemon Doujinshi, you might as well check out I Am an Elf! I hope you like this fairy's recommendation. Muah ~😗
