The Gate Keepers of All Things [Prince of Tennis Fanfiction]

What would happen if there was a group of middle schoolers that will be deciding the future of their tennis career? They were all trained by a professional tennis player at a camp on a private island with high schoolers. What if said high schoolers and middle schoolers could cause major chaos on the court? What if most of them were something called Gate Keepers by people who only knew the gates but not them personally? By others they're called by their correct titles which only a few are really well known. A few of them are daughters & sons of famous individuals: one is a daughter of a CEO & fashion designer along with the niece of a former professional tennis player, one is the daughter of a former professional tennis player & a professional basketball player/personal trainer, one is a daughter and one is a son of a violinist/ pianist & a director, & one is the daughter of an attorney. Most don't come from the best of backgrounds, but that doesn't mean they're pushovers. Together they're team is invincible, separate they are weaker but not extremely weak. Most of them are talented in other areas besides tennis.

I got the idea to write the about my Prince of Tennis Ocs and about the gates from @Mana_ko_R because her fanfictions inspired me to write it along with other writes whose stories I love. If you read any part of High school secret, you guys will realized they both have Ayano as a character. Ayano was originally a Prince of Tennis oc to begin with, I just had to modify her character somewhat for HSS and give her different parents for it.
