Real-life young man Tamaki Ren traveled into the world of "The Prince of Tennis" and became a second-year transfer student at Ritsukai University. With the abnormal mental power given by time travel, he can see through all tennis moves and the fate of the characters, but due to his physical weakness, he can only stay behind the scenes temporarily. In order to reverse the ending of the original work "Rikkai University's dream of three consecutive championships was shattered", Ren Tamaki sneaked into the Rikkai Tennis Club as an observer and used accurate predictions and psychological tactics to win the attention of the main players. He promoted physical examinations for all employees and promoted Yukimura Seiichi's early treatment; he guided Kirihara to control demonization; he even formed a secret alliance with Nioh and Yagyu. When the draw for the Kanto Tournament is announced, with Seigaku and Hyoutei surrounded by powerful enemies, Tamaki Ren must accelerate his growth while Yukimura is hospitalized, using the racket in his hand and prophetic memory to pave a different championship path for Rikkai University. It is private and not very friendly to Qingxuechu. It will only write about national competitions. U-17 is too fantasy to write about.
