Fuu's relationship with Mugen and Jin is apparently sororal (of or like a sister) where she has a bright and trusting personality. She is highly prone to accidents, getting lost, and finding trouble, although she is quite practical. She often puts on a front of being more worldly and experienced than she actually is so as not to appear completely idiotic. She always seems to get into trouble and needs to be saved many times. She really really loves food.  shes 15yo and lives in the 1800's.
