Nathalia Bortros

"I love Bill 'cause he's the softest, nicest, warmest man I've ever met. It wasn't uncommon to see someone all beaten in Bosco, especially escaped slaves, but unlike him, they all gave up half way through and fell. He just kept standing and going. I guess that's when I wanted to know him better. Well, that and the head was a charm point."

- Nathalia speaking of her love and first meeting with Bill Nathalia Bortros (ナサリア ボルトロス, Nasaria Borutorosu), more commonly nicknamed "Nat" (ナット, Natto) by her accomplices, is one of the few factionless Mages within the Under Wonder Guild, working as the waitress and guard of the base, alongside her husband, Bill, who works as the bartender, cook and janitor of the guild's bar.

She is given the title The Kitten (子猫, Koneko) by the Guild Master, Alexandria McGee, functioning more as a tease than a serious title, compared to the other mages.

Trivia

 * Nathalia's title of "The Kitten" is more of a reference to Alice's cat in the movie and novel.
