Harriet Bartholomew

A young girl with no known living relatives, Harriet "Hattie" Bartholomew still possesses a childish innocence and believes in elves and fairies. She likes to wear a top hat and is often seen flanked by her fiercely protective pet dog Walton. Somehow, she is able to communicate telepathically with Frank, whom she calls "Yousei-kun" (Mr. Elf). Due to a traumatic childhood incident, Hattie becomes paralyzed with a neurotic fear at the mere sound of gunfire. (Source: AnimeNfo)
