I've seen that girl before as a character from a sprite based game. I had downloaded her into my MUGEN roster a few years ago and made a few palettes (I'm still somewhat good at making palettes).
"You picked up the wrong guy to summon, little miss."
Quite a funny crossover since Alice from Asura Blade summons skeletons to help her at her battles. Such a shame there are only few fanarts of Asura Blade (and mainly with Alice instead of dat-ass Footie: http://www.arcade-museum.com/images/106/1060775543.jpg ).
By the way, you must definitely play Asura Blade. One of the most kick-ass fightings I've ever played.
