This piece is a free gift that came with the commission paid by me and done by none other than Amaipetisu herself which can be seen here: Infinity - MIthra.
As mentioned in the commission post, this is my character codenamed "Infinity" visiting the world of Vana'diel (Final Fantasy XI: Online for those that don't know) and taking on a Mithra form, unknowingly keeping her uniform and weapons though and trying to pawn it off as some high level gear.
