If there is any story progression at all, sorry, but you'll have to post it in the RP.
The Arena is for fights and fights only. If you want to make a character sheet with a bio for your character, that's all fine and actually recommended. [I might be making a tournament some day. Might be fun.] However, once you start posting, it must be fighting and nothing but that. Dialogue is cool, too, if you want to add in that good 'ol drama.
Oh! And try not to sigh or smirk too much.
