The Boss fight against Filia is always set to Nightmare difficulty and has 300% more health then usual regardless of the difficulty setting chosen at the beginning.

Sounds like Alpha-152 from Dead or Alive 4. Chick knows how to play the game way too well and you're lucky to last a minute if you don't know how to counter. This becomes a pain in the ass when you want to unlock Helena (beat story mode with everyone, which I assume you need to do in SkullGirls as well).
