She is a scheming freelance writer (and is conspicuous in her lack of writing). A model example of a parasite single, Kitsune lives to enjoy the easy life, and frequently scams others by any means possible. She is frequently drunk, and bottles can be found hidden all over her room. Her greatest joy seems to be teasing Keitaro, even though she clearly cares for him. She is a school friend of Naru and tries her best (or worst) to make Keitaro and Naru get married. In order to maintain her finances, she often bets on horse races. In the anime, Kitsune speaks with an Osaka accent, which seems to imply a connection between her sly, money-minded personality and a common stereotype about people who hail from that region.
