How can Henge be Genjutsu (Illusion)?. In multiple parts in the manga and anime, the charachters change their form using henge and their physical aspects actually change, not just look like it. For example when Naruto and Gamabunta are fighting Shukaku, Gamabunta asks to be Henged into something with claws and such, If it was just an illusion, what would be the point of changing?
