I recommend the book "Master of Data tennis" to you. The novel told the story of an otaku who transmigrated to a professional tennis game and gained the ability to digitise his body. You can see his tennis matches in this novel, and the scene of his PK with the tennis god, Echiguro Minamijiro, is also presented. Then, the protagonist accidentally transmigrated to Slam Dunk and started a different basketball journey. I hope you like this fairy's recommendation. Muah ~😗
