Female characters get the skirt to go with their yukatas, but male characters... there's not really a lot of options.

So I was just wondering if there's any chance of a hakama being put into the game for us guys?

In case anyone's wondering what it is, it's basically very loose-fitting, pleated trousers traditional to feudal Japan. (Not traditional with yukata I know but the yukata in game aren't traditional anyway.) Or to quote wikipedia directly:

The clothing worn under the bōgu comprise a jacket (kendogi or keikogi) and hakama, a garment separated in the middle to form two wide trouser legs.
