Prince of Tennis: Midsummer at Rikkai Dai

Yu Zhi Lian, a young man from the modern world, transmigrates into Prince of Tennis and becomes a second-year transfer student at Rikkai Dai. The extraordinary mental powers he gains through transmigration let him see through every tennis technique and character's fate, but his physical weakness means he can only stay behind the scenes for now. To change the original ending, where Rikkai Dai's dream of three consecutive championships falls apart, Yu Zhi Lian infiltrates the Rikkai tennis club as an observer, winning the regulars' attention with his precise predictions and psychological tactics. He pushes for the whole team to get medical checkups, helping Yukimura Seiichi receive treatment early, guides Kirihara in controlling his demonic transformation, and forms a secret alliance with Niou and Yagyuu. When the Kanto Tournament draw is announced, with formidable opponents from Seigaku and Hyotei all around, Yu Zhi Lian must grow stronger at an accelerated pace while Yukimura is hospitalized. With his racket and memories of the future, he will pave a different road to victory for Rikkai Dai. This story has original elements and may not sit well with Seigaku fans. It only goes up to the National Tournament; the U-17 is too fantastical for me to write.
