i was looking at itachi vs sasuke fight and i noticed this
zetsu is watching the entire fight, and he said this
^^^^why dont zetsu recognize amaterasu????????
REMEMBER ZETSU KNOWS EVERYTHING ABOUT MADARA
this PROVES madara doesnt have amaterasu because zetsu would have known about it already unless kishi contradicts his manga
and since madara can use susano without amaterasu, this proves susano doesnt require amaterasu
this proves the databook wrong too......unless the databook is talking about just ITACHI's susano
EDIT: here is my thread other thread about susano requirements
