Since the start of the manga I was wondering about something. You may think its totaly insignificant or you may think that Im stupid to not know but anyway:
Why do shinobi have to perform special seals before using any technique ???
I mean how imortant are they and how exactly they make jutsus to work ? I know its a rather complicated question that would require Kishi himself to explain but maybe theres someone here that can explain. Or you can create your opinion about it.
