New Prince of Tennis: Kintaro Toyama

Transmigration + multiple heroines + System + tennis + tycoon + invincible

An anime fan transmigrates into the impoverished boy Kintaro Toyama and unexpectedly activates the Tycoon System, beginning a double life of “playing poor and face-slapping” and “becoming a tennis legend.” He first shows his talent at Shitenhoji, playing the pig to eat the tiger as he crushes those who provoke him, while secretly training in dark matter tennis techniques. At the same time, he uses his money to quietly improve his family’s circumstances and win the hearts of ten girlfriends. He replicates the world’s most extraordinary tennis techniques, sweeping the regional, Kyoto, and national tournaments before becoming Japan’s ace at U17.

On the world stage, he crushes elite players from every country with incredible techniques like light-speed returns and stopping time and space. He wins five consecutive career Grand Slams and is crowned the “Tennis God.” He also builds the Golden Glory Club and a tennis academy, recruits talented students from around the world, monopolizes the tennis world’s resources, and becomes a legendary patriarch.

He keeps his cards close to his chest throughout, with plenty of memorable moments pretending to be poor, yet uses his tycoon wealth and invincible strength to overcome every crisis and doubt. He eventually becomes the greatest player in tennis history. Together with his ten girlfriends, family, and trusted followers, he enjoys eternal youth and unlimited tycoon privileges, continuing to write a perfect life at the peak of his legend and leaving behind a tennis myth for the ages.
