This is a fan world based on "The Prince of Tennis", where Tenchi Fuyu is transferred to Seigaku and Tezuka's class. At first, he was unknown in the tennis club and faced the problem of improving himself and the team's strength. By chance, he accidentally obtained the binding system. This system can bind others to obtain abilities, and can also permanently improve related tennis attributes. With this, he can imitate his opponent's style of play at will, and his strength far exceeds that of his peers. He helped the Seigaku players reach world-class levels, achieving three consecutive national championships and two consecutive world championships. After becoming the world's number one, he launched a challenge to the legendary strongman Echizen Nanjiro.
