I think Sarutobi did have some kinda learn techniques fast thing because in one of the naruto show (can't remember which one it was) i think it said that 3rd hokage had a nickname "the professor" cuz he had bunch of jutsu or something?
This video have one hell of an Narusaku moment, there is an scene on it were Sakura is crying with Naruto in her lap, supposely dead, and than, in the ending of the video, suddenly, Naruto hand reachs Sakura face, and he smile to her, and Sakura break down in tears and hugs his chest, it's just marvelous, I can't even.... Oh, and about the rest of the video, it's just an build up of Naruto and Sasuke lifes as shinobis, but overal, it was nice.
Here is the video:
That video was.....was...... was awesome!!!! but when i watched it i noticed that Naruto has that brass knuckle knife that Asuma use agaist Hidan how did Naruto get it?
