The story is about Ryoma Echizen, the main character, who enters a prestigious junior high school for tennis, joins the tennis club and aims to win matches in team competitions to win the national tournament. The story includes explanations of the rules and rules of the game so that even people who do not know tennis can read it. In the beginning of the serialization, the manga depicted the techniques that tennis players can actually use, but from the middle of the series, the manga changed its course to focus on wacky techniques, and after the main character achieved a state of selflessness in volume 26, the depiction of inhuman techniques became more prominent.
