xD Aha. Nice way to disprove me, dude. Even if you are joking, which I'm sure you are.
Nevermind what I said. Continue, continue.
Welp. Awright.
Roxas has TWO RINGS, one representing HIM and the other representing XION, who is WHITE representing LIGHT because she is MOST DEFINITELY WITHOUT A DOUBT ON THE DOT KAIRI'S NOBODY (despite the fact that no one has confirmed this and damned if I can quote a single interview that even leans in that direction). The other one is BLACK representing HIM since it's on his INDEX FINGER and INDEX IS FIRST.
Ven has NO RINGS which means he isn't CONNECTED to Xion in the way that Roxas is (CAPTAIN OBVIOUS TO THE RESCUE) but Ven also lacks GLOVES--Sora and Riku and the better part of the Organization ALWAYS WEAR GLOVES. The people who don't wear gloves are NAMINE and KAIRI, which means Ven is intimately connected to THEM (KAIRI WEARS BRACELETS TOO SEE SEE!!11!1).
So, ultimately:
VEN IS A GIRL.
AND ROXAS IS ACTUALLY A HOBBIT.
