Kid is the leading heroine of Radical Dreamers: Nusumenai Hōseki. On the outside, Kid presents herself as fun-loving, carefree, and fearless. Serge notes, however, that this personality is a facade; deep within, Kid broods over the death of her sister and surrogate mother, Lucca. She speaks with an Australian accent, which Serge says she commandeered due to her love of travel and adventure and includes colloquialisms like "mate" and "bugger" into her speech. Of the three thieves playable in the game, she is the only one that never, at any point in the game, faces the player directly.
