i remember jiraiya saying its the technique that the fourth left behind, which means that its probably him that created the jutsu
mastering a technique is the hardest when your the first one to attempt it, if its easy than anyone could have thought of doing it
P.S. How come when I play the more recent episodes, the sound kinda skips every few minutes?
try turning the volume up on other applications
like when i watch stuff on kazaa with low volume, then i watch stuff on wmp, it skips even if you have it on full volume (in wmp), so what i did was go to kazaa and turn up the volume on that, it solved my problem, i dont think its a codec problem or anything
