Information - Voices
Fee has two very different voices, if you bother to switch between the Japanese and English audio options throughout the game for the heck of it.
Her Japanese voice is very soft, almost frail. It's high pitched, and sounds like a typical anime Japanese teenaged girl. She is voiced by Natsumi Yanagisa in the original Japanese game.
Her English voice, by a very sharp contrast, sounds very grown up and deep. At first I didn't believe it to fit her, but as the game progressed I've grown to like it.
