Fuu is the magic knight of wind and her powers focus more on defense than offense. She is capable of healing almost any injury, except for death and sickness. She is the smartest of the magic knights, and uses this to her advantage to help save Cephiro and aide the knights on their journey. She is the last to discover her powers (out of the three magic knights) and begins to feel slightly frustrated before she finally does, as she starts to believe that may be she is not capable of magic. When she does receive her powers, however, she is able to use them to heal and save Umi from critical injuries sustained by an attack from the ice witch Alycione - a villain in the series.

Fuu has short, blonde hair and deep green eyes. Fuu wears glasses, but does not need them when she transforms into a magic knight. Her school's uniform is a medium shade of green, while Hikaru's is red and Umi's is blue. Fuu has an elder sister named Kuu, whom she often looks upto as a role model.
