I JUST REALIZED THAT ANTOINE IS BASICALLY RUROUNI KENSHIN IN DEMON FORM!!! Bahahah. After reading Dark Jack's description, I was like "Oh man... MALIGNITAS SHOULD HAVE BEEN A REVERSE BLADE!"

Edit: I picked Ty of all the characters for him to make a 'goal' because of her wind-like nature and how I believe her original desire for a 'place' does parallel his search for 'himself.' Not to mention, her current persona would probably mesh fairly well with a whimsical street punk.
