10/10 would ask to be companion. That, and my preference for females, and you have a happy couple living on apocalypse street 308.
Just the persona "feel" I get from this character tells me you would first meet her serving one of the casino bosses, a kind heart, but constantly tortured by the casino bosses, and as such you must save her from her slavery to them.
Afterwards I would think she would put you on a quest for vengeance, then, once completed, would specialize in sharp melee weapons. But this is just an assumption though, from a guy who loves Katanas, and anything similar.
Actually, her favorite weapons are a 12.7mm pistol and shotguns. the sword is actually situational or a backup weapon. And... well, yeah, she's a kind heart, in the sense she's very self-sacrificing, but a little less gentle than you describe her origins... Among other things, she has broken a unicorn slaver's horn with a police baton, fed a guy who was working with slavers into a rock crusher, and drunkenly cut a bounty hunter's nuts off with a dragon claw she found in a museum exhibit while singing about how much she loved whiskey.
i recently stumbled across it it stands in not a single aspect short to the original FO:E, and in some even tops it off (blackjacks character-development and that of her friends are genius as hell, for example)
