Ushio is a water master who spent basically her whole life in a water-filled protective suit due to airborne contact dermatitis. Then Gero came along and cured her—which she complains was annoying because now she actually has to pick out clothes every day. Fans often note the irony that she's been spotted genuinely excited while shopping for outfits, so the whole "inconvenience" thing might be less than sincere.
She's got bigger ambitions than just being a master though. She's studying for an MBA because she wants to approach the job from a more business-minded angle. Beyond that, she's into stand-up comedy and has mentioned wanting to catch a live show someday.
