I know this is a pretty... weird or interesting question, but in some cutscenes and art Xion is wearing her Kingdom Key on her left hand!

 

People claim that this is a possible thing since she is a REFLECTION and gave the ability to both Roxas and Sora. That's why they are able able of using two Keyblades.

 

Also, Ventus was meant to be left-handed. On Kingdom Hearts 2 Final Mix's Secret Ending, Ventus wears his keyblade on his left hand most of the time.

Wow that's pretty cool never noticed that before! It definitely does make sense so it's possible.

I believe she is ambidextrous.

I'm sorry, what?

It means equally skilled with both the left and right hands.

What's so weird about "ambidextrous"? Never heard that word?

Sometimes she's got the Keyblade in her left hand, sometimes it's in her right. I'm going with the ambidextrous theory.

Not in english, no.

Well your lexicon has just expanded slightly

Another proof. When they are holding their ice creams Xion is the only one who hold with left.

I'm ambidextrous!

Oh nvm weird in days she is holding it in the right hand and in the DDD opening on the left.

Yeh she is ambidextrous.

 

Edit: So found out this scene in HD Remix from a flashback scene that she was holding it on the left.
