Ryoma Echizen just joined the Seishun Academy's tennis team, which is known for being one of the most competitive teams in Japan. Its members are incredibly talented, gifted, and athletic. With rigorous and extremely intense practices, the upperclassmen of the team expect the very best from themselves and they expect even more from the new members of the team. While most of the freshmen are on pins and needles hoping they won't get cut from the team, Ryoma Echizen is confident, cool, and collected. Some might even say he's cocky, but at least he's got the skills to back up his attitude. With his virtually unreturnable "twist serve," Ryoma is sure to make the starting team.
Join Ryoma and the other first years, as they train hard, make friends, and try to find a place for themselves on the team. And meet Ryoma's cute but chronically shy classmate Sakuno Ryuzaki. She's got a big crush on Ryoma, but will he ever notice her? Ryoma Echizen is the Prince of Tennis. He may be ready for the Seishun Academy tennis team, but are they ready for him?

Kaname Okiura, a student of Prefectoral Umineko Shougyou High ("Umisho" for short), joined the school's swimming club in order to learn how to swim, but the club is filled with weirdos, let alone teaches him swimming. Then, a sunny, happy-go-lucky girl named Amuro Ninagawa who was transferred from Okinawa joined the club. Her extraordinary underwater speed and unorthodox swimming style (plus her personal habit of nude swimming—a powerful magnet to teenage boys) surprised every club member, especially Okiura, because she reminds him of a mermaid-like creature he saw only once in his early childhood.

Akagi, after being rejected by a girl that he likes and punched by a rival, Rukawa, for accidentally stepping into his confession moment with the girl, wants revenge against Rukawa for various reasons.

Kurogane Hiroto is in high school, where he is academically the top of his class but literally the worst in physical activity. Born with a weak body, he has no endurance, speed nor strength and Hiroto wants nothing more than to be a hero. Fate teases him by giving him phenomenal eye sight, which allows him to see well beyond anyone else in sports, but his body is not able to react to any of it.

He learns from his friend Shiratori, who wants to recruit him for the Kendo team, about a rumor about a ghost named Tojo Sayuri, who wields a katana and haunts an alley in the city. Half curious, Hiroto goes there only to find that the ghost is real and that Tojo Sayuri has been looking for a successor to her Sakura sword style for 150 years. Sayuri chooses him as the successor after being able to dodge her attack and forces him to learn the Sakura style. Even with the help of the ancient swordsman ghost, Hiroto has to overcome his poor motor skills in order to be the hero he always wanted to be.
