Well no one has said that they are relatives. Having the same last name doesn't mean anything. Rock Lee isn't Bruce Lee's son (just his student ) I don't think Asuma is Konohamaru's dad or the 3rd's relative.


and Itachi_ he says -dono to Kazekage. Dono is even higher than sama, it isn't used anymore in Japan. It was used by samurais and stuff.
