I recommend two novels to you, Dragon Ball God-Level Saiyan and One Piece: Sign in to Semi-Human Bloodline at the Beginning. These two novels were both light novels and derivative doujinshi novels. The main characters were of Saiyan descent and took place in the worlds of Dragon Ball and One Piece respectively. If you like Dragon Ball and One Piece, then they are not to be missed! I hope you will like these novels.😘
