Prince of Tennis: I'm Atobe Keigo's Younger Uncle

(Pairing: Yukimura. No female lead. Rikkai Dai wins three consecutive championships. I just want to give Seiichi a perfect ending, so there are lots of headcanons. If that bothers you, please click away.)

In his previous life, Jiang Ling was a successful entrepreneur and one of the five richest people in the country. His only hobby was playing tennis. Believing that everything should be done perfectly, he accidentally made it to world number one. When he opened his eyes again, he had arrived in the world of Prince of Tennis.

Atobe Ling: Seiichi, I'm eight years older than you.

Yukimura: A-Ling, don't you like me?

Atobe Ling: Seiichi, I'm Keigo's uncle.

Yukimura: A-Ling, don't you like me?

Atobe Keigo: I thought of you as my rival, but you want to join my family!
