Fuu came to Mizuno Clan one fine day during Mistral Jamboree. He was but a baby but he looked like he could become a decent warrior and Athame gladly welcomed him.

Until Fuu's arrival, the only capable fighter of the Clan was MoonShadow, a grumpy Imperial with much wisdom to share. Fuu was patient and eager to learn so the two got along quite quickly, MoonShadow even acting like a father to the younger Imperial.

Then young warrior Xyro arrived. The Wildclaw was looking for a Clan to settle in and as usual, Athame warmly welcomed the young lady Dragon. At first MoonShadow didn't like her much, she was distant and wary. But Fuu liked her from the begining and he patiently waited for Xyro to trust him and open up. They became good friends quickly enough and after quite some time training and fighting together, they finaly became companions.

Fuu is very protective of his mate and his Clan, but he's never too quick to fight. He will try to talk rather than fight.
