Changed the Red Mage tag to Ninja since it seems more like the artist took some liberty designing fitting gloves for the Scorpion Harness.
Since the gloves would be the only thing pointing towards Red Mage, which has entirely different gloves in its AF set, I'm gonna go out on a limb and assume that this is supposed to be a Ninja and not a RDM/NIN, which would have been implied by the ninja tools.

At least that's what a friend and I concluded after looking into the matter in a sudden burst of nostalgia.
