rinnegan is one of the three doujutsu and its most powerfull. nagato have madara rinnegan his techniques are 6 paths like asura etc but all techniques cannot be used without both eyes as we seen so why doesnt kaguya have narakka path, asura path etc like nagato, madara and why doesnt she have limbo, same goes for sasuke does it means all rinnegan has different techniques like sharingan?
