Prince of Tennis: the Strongest Store Manager

Traveling to the world of "The Prince of Tennis", what Wan Jie wants to do most is not to reach the top of tennis, but to run his own shop well. "A medal that makes you climb walls when you put it on, a mouse pendant that can be rematched by crushing it, and a tennis racket that can steal stamina. We don't sell any of these in our store!" "Hey, don't leave. There are still replica shops of these things. It's just that the effect... Is a bit watered down." "It's strange, how can I, a shop owner, become the national champion?"
