Kingdom Hearts: Light by Darkness
Final Fantasy VIII

''A follower of Seifer, and a member of Twilight Town's Disciplinary Committee. ''

''She never says more than what she has to, being a very simple girl. She has Seifer's complete trust, and will always make herself useful for him.''

Kingdom Hearts: Light by Darkness
Fuu is first seen guarding the Old Mansion as one of her chores as part of Twilight Town's Disciplinary Committee, while Kairi was chasing Vivi, mistaken as a Heartless. Fuu makes a deal with Kairi; if Kairi can defeat her in a Struggle match, then Fuu will let her pass by. Kairi ultimately wins the battle, and so Fuu lets her go inside the mansion.

Later on, she can be seen in one of the matches if the player chooses to participate in a Struggle tournament.
