My favorite female fighter in SCIV, even if she's just a bonus character that has the same fighting style as Certantes, whom I dislike because of his ending.
She wasn't obscure in some way like every other bonus character in the game was, so it didn't make much sense for her not to be her own character, especially when she has pretty much the same fighting style as Cervantes. (Just realized I mis-spelled his name in the first post. Oh well)
And yeah. A four swords moveset definitely would've been epic in that game.
