Tennis: Defeat the Rebels at the Beginning

In a parallel world, tennis is all the rage. Yanaggi became a junior high school student in the Dragon Kingdom, and happened to encounter the return of the rebellious ninja Fujiwara Tenkei. He used the system role-playing skills to defeat the traitorous ninja and broke Fujiwara Tenjie's mentality. The country where the rebellious ninja came from was completely unconvinced, so Yagyu embarked on the path of first penetrating the Sakura Country and then dominating the tennis world.
