Yeah, plenty of them. Just look on the front of the OOC thread under Accepted Characters and look for girl names. None of them have been paired up but Hayley's character. Everyone else is a boy.
Or, wait, were you talking about partners? Because, no, everyone's partnered up, and none of the partnerships are going to be changing at this point. So I guess if you are planning on some sort of romantic something look at what I said above. I can't say I recommend your character randomly falling for someone though. Believability is key, and it helps especially if someone has mutual interest, which may not be the case for anyone RPing a girl. xD
tl;dr Yes, there are. Make sure any romance is okay with the other person. Unless you were talking about partners in the tournament, then no.
