[Mainnet King] It’s not too much to use magic to play ball, right?

Introduction: The story of a guy who copied the ‘Curo Card’ and its magical power, and under the influence of the members of the Rikkai Tennis Club, truly fell in love with tennis. The protagonist joins Rikkai. Rikkai won three consecutive national championships and sixteen consecutive victories in the Kanto competition. (PS. The writing is not good. It feels like a full diploma. There will be a little bit of Sakura's plot, but it will not account for a large proportion.) In addition, this article has a lot of private settings, and the system is basically just a decoration. There is no female protagonist in this article! CP Yukimura. I originally wanted to write the main story, but then I felt like I couldn’t write it like this... So let’s just do whatever you want ╮(︶﹏︶)╭ Also, the writing is not very good, so I hope everyone can tolerate it.
