The Omnipotent Nioh-Kun

Nioh-kun, the Nioh-kun who has won four Grand Slam trophies in ten years and ruled the entire tennis world, has once again come to the new world. The system ran out of energy when sending him and Sanada back to their original world. Sanada successfully returned to the original world, but Nioh fell down halfway, right on the mountain behind Tatekai Dai. When he looked up, he could see a familiar Bai Mao playing a tennis match with another person on the court of the Rikkai Tennis Club, and was being rubbed on the ground. ... Even in a parallel world, would Nioh be so weak? Niou-kun, whose official age is twenty-nine, but his actual age is unknown, decided to find a way to teach the kid below who has the same face as himself. I wasn't so weak when I was twelve, he thought. The story of the super-powered Nioh who travels back to the original story and becomes the coach of the Rikkai Tennis Club will change the original ending from the perspective of the coach. The fourth part of Nioh-kun is a comedy about persecuting everyone (probably). Notes: 1. True persecution of all members, and half a group portrait. 2. Obviously, Rikkai has won three consecutive championships, and the super-powered Nioh can be regarded as the golden finger of the original Nioh. 3. It will be very long, more than a million, and will be large and daily. 2023.9.29 Enter V Intention: strive to achieve the future
