Oh good grief. This one I could go in-depth gushing over, because I have so much love for two teams from Prince of Tennis. The series itself is really stupid, but the characters are so much love... and I have such undying affections for both Rikkai and Shitenhouji. Plus I take great pride in being one of the first people to play Shiraishi in an RP and still be playing him in a game now. That's like 7 years of consistency lol. But like. In one team (Shitenhouji) you have a speed freak, a perfectionist, an overgrown hippy, a hipster, a tag-team of comedic idiots, a guy no one ever remembers, their hot coach, and finally the hyper little redheaded cherry on top. But then you have the other team (Rikkai) who are full of serious badasses. They're just this powerhouse of dedicated players that I honestly can't begin to gush about because I've loved them for so long that I just can't deconstruct all that love without rambling too much.

That said, I've only ever gotten into one other sports anime, and that was Kuroko no Basuke. I don't actually love teams as much as I love characters for it, though. Granted most of them are from Seirin but it's hard not to love those dorks.

Also, my icon is a fanart of Kirihara from team Rikkai lmfao
