Doing My Part for Rikkai's Three-Peat

Completed works Where Did That Huge Child of God Go? Ongoing works The Child of God Arrives in Beika Town Coming soon Yukimura's Miracle World Tour The Beloved of a Wealthy Young Master What do you mean, "Prince of Tennis Training Plan"? Just because I opened an email? Besides, doesn't Rikkai Dai already have several players who are good at tennis? Why not bind them to it instead?! Xu Qingchi was told to help Rikkai Dai win the championship. He's just a poor guy bound to a goofy System. When he sees the tennis club members, he thinks, You're all so amazing already. Why do you need me? Am I supposed to be a mascot? Huff, puff. One piece today, another tomorrow. I'll do my part to help Rikkai Dai win three championships in a row! I'm sticking firmly to Rikkai Dai's 16+3 lineup. Middle school Yukimura is the strongest, and that's final! Seigaku fans, stay out. Lots of original settings. OOC warning. Tane shima and Irie are seniors at Rikkai Dai. No CP, everyone is friends. The U17 arc will be mentioned, but not covered in detail. Note: There are two Hattoris. One is from Rikkai Dai, and the other is the familiar Kansai detective. (Thanks to the commenter who pointed it out.) Theme: The sincerity and purity of young athletes
