😋I recommend the following two books to you: 1. "Being a Masked Rider in the Infinite Style" is a light novel, a derivative doujinshi novel. The main character's ability is the Masked Rider's Void Self. Later on, he will obtain a belt transformation that focuses on chivalry. It definitely meets your needs. 2. "Infinite Time" was a sci-fi novel that traveled through time and space. The main character had the heaven-defying ability of infinite rebirth. In various magnificent epics, he changed his fate and also had the ability to transform. I hope you like my recommendation, Mwah ~😗
