Xiao Fei is the son of Da Fei and adoptive son of Dai Bo. He's a flying chicken and always follows Seven around.

Dai Bo introduces Xiao Fei to Seven as a means to fly away from tough situations. Since then they are always together and Xiao Fei becomes more and more attached to Seven as he keeps helping people.

Happy and innocent of the time, he can also get angry if someone he knows is hurt or in trouble. Xiao Fei is also very brave as he is willing to fight to protect Seven even against opponents that are stronger than him.
