Samurai possibly?

[Kyuuen]

Most likely is. If you look at the scabbards on said character, he obviously has two. Traditional Samurai; and correct me if I'm wrong here, typically carried two Katana. The Katana and then it's accompaniment the Wakizashi. Though from the picture I can't really tell if the secondary sword is any shorter or not. However, the uppermost Scabbard is holstered in such a way that the blade would be upwards while holstered, which is something again done by some Samurai.

Again correct me if/where wrong, I'm by no means an expert.

That Scabbard seems to have three holsters for sword not only 2 (but one sword seems to be missing).... Zoro?

Maybe one of the swords is merely missing to show those are actually scabbards and the one still in it's "sheath" is a gun handle/trigger for the all too common Garlean gunblade mode I am sure his weapon has? D:
