The Prince of Tennis: Moonlight Senpai's Path to Winning Over Cats

[This story contains a lot of original headcanons and is a crossover. Please treat it as a parallel story. I personally want Rikkaidai to win the championship consecutively, so readers who support Seigaku, please don't come in.]

When Ochi Tsukimitsu saw Mouri Jusaburo ten years in the future through the Ten-Year Bazooka, he knew he was destined to fall for him in this life.

(The high school students at Rikkaidai and their backgrounds are mostly made up. Side couples: Hane/Fuji, Tezuka/Sanada, and Tanaka/Kirihara. I'll add more later if there are any.)
