"Well, I only use one sword, and it's not very short. It's actually about 6 feet long."
The trope page for Baten Kaitos lists Sagi's katana as a BFS that's about as long as he is tall.
Heh. Wanna try Fire Dragon, then? Alrighty.
Now I just gotta set up some training stage.
-goes to an empty part of the room and makes several fluid motions, activating a spell...-
Fantasy.
-Surroundings ripple as a dreamspace imposes itself on reality. From the floor rise ranks of faceless soldiers, their bodies looking like marble and their armour shimmering with pearly surface.-
Well these dummies you will be practising on
-droplets of light flow from Kashi to him, each one flashing specifics of energy manipulation for the moves and settling in his memories-
Annd now lets try them. Just concentrate on the name and your memory shall provide.
First Charms are quite simple - Flash-Fire Technique...
-and to the name come the memories, of directing fiery energy through his own body to boost reflexes-
...Flame-Flicker Stance...
-heat causing ripples in the air, obscuring the exact position and making it easier to dodge and block the attacks-
...Searing Fist Attack...
-a quick strike, leaving an ethereal thorn of fiery Essence to burrow into the victim, distracting him with pain-
... and Perfect Blazing Blow.
-and now the fires become manifest - a thin tongue of flame coiling around his weapon or his fist, burning through the armour to reach the flesh beneath-

Well that kinda points towards the Air Dragon Style... However, Fire Dragon could be used both unarmed and while using a pair of short swords, thus adding to your usual style.
