SAO Anime Trivia 1 - The Axe Dual-Wielder

You can dual-wield axe in SAO!? Seriously!?

There are 3 possibilities :

1. Dual-wielding axe in SAO is actually possible, it's just Kirito never mentioned it.
2. He's one of the players who own unique skills (there are ten of them after all).
3. The anime staff made an epic fail :)

UPDATE :
That man is fully capable of performing sword skill using his dual-axe, as shown by 2 pictures below.
