Description

Fuu is the polite and soft-spoken one of the trio. Though she looks weak on the outside, she will step forward to take responsibility when the need arises. Fuu's polite nature makes it hard to voice her opinion and has trouble taking the "first step". In the flashback where she recalls how the three girls met, it was a rainy day and Hikaru lent her umbrella to another person leaving herself without one. Fuu was watching from afar, wanting to invite Hikaru to head home with her, but was unable to speak up. It was Umi who took the initiative to suggest all of them head home together.

After watching Hikaru failure to stop the Cefiro invaders, Fuu ponders if she is able to fight like Hikaru. Windam then asks to her if she has the courage to fight against fate and must show him her "first step" of courage, she is also given the Ovum by Mokona. She tries to hide it from Umi as Umi is still uneasy about the turn of events but she finds out in the end. Fuu leaves to find Windam and is attacked by Ferio. After watching Ferio destroying the city in order to find where Windam is hiding, Fuu conjures the courage to take the "first step" and successfully summons Mashin Windam.
