Fuu is Jamie's little sister, who between her and cousin Xion managed to convince him to come to Lumi.

She left behind someone she really likes Ferio in Centropolis, and now has a lovely crush on Hawk.
During the Festival Hawk is going to ask her out on a date. (What do?!)

Fuu is horrendously naive when it comes to matters of the heart.

She'll be interning at the library over the summer, and tinkering with everything computer-related when she has the chance.

She loves being helpful and tries to get along well with everyone!
