Dropping the Jutsu, Tsunade helped him to his feet. "That was Kokuangyo no jutsu, also known as the Art of Infinite Darkness. It is a Genjutsu that my grandfather perfected during the conflicts with the Uchiha clan before Konoha's founding. Unlike the standard Genjutsu that effect chakra signals of an individual directly, this technique forms a void in the chakra within a certain area, removing all impressions and ocular senses of even the strongest ninja. Among other things, it is said that this technique allowed my Grandfather and Grand Uncle to match the forces of Uchiha Madara himself."

Gaping at the history of the technique, Naruto could not help but jump up and down in excitement. This was the coolest ability he had ever seen! Plus it was the personal ability of the Shodaime himself! With such a technique, his dream was that much closer! Pausing in his celebrations, the blonde had a thought. "Hey Baa-chan, if that technique was so awesome, why haven't I ever heard about it? I mean, everyone knows about the Shodaime's Mokuton, but a technique that can block eye techniques still sounds really cool. I'm sure Iruka-sensei would have mentioned something at least?"

Frowning, Tsunade sighed. "It's not that simple, Naruto. When Grandfather and Uchiha Madara formed Konoha, they had to make a number of concessions with the various clans that inhabit it. Both the Uchiha and the Hyuga requested that this technique be labeled as forbidden, only to be passed down to the Hokage's and their direct successors. Since both the Byakugan and the Sharingan have demonstrated a weakness when facing them, it would have only aggravated relations to continue to use it so openly. But since there are no longer any official loyal Uchiha and the Hyuga are currently on my Shit List, I can see no harm in teaching it to you. After all, one of our main opponents is an Uchiha after all."
