Re: Animators are re-using characters
Kishi does not make characters in the fillers, that person was a creation of the animators.
Pakura is not a filler character she has been in the manga
So this episode will be about the sand village scorch style user Pakura. It is just a coincidence that the filler character looks exactly like her, I don't think the artists had seen Pakura when they drew the filler girl.
