I'm not sure if anyone you realise this, but the reason why the mission was called a "Super A rank mission" was that Tazuna had this irritating habit of putting the word "chou" (super) in front of every sentence he made. Thus came the expression of "Super A rank". Go check if you don't believe me.Originally posted by: poopdeville
Maybe English isn't your first language, but in English, the word "super" means "greater than." So according to AonE's translation, the "super" was not just for emphasis but to denote that the mission was harder than A rank.Originally posted by: XanBcoo
Your original question has already been answered - The "super" was just for emphasis, and obviously Kakashi never told Sandaime about the Wave Country mission.
