Naruto Shippuuden Episode 277

[DarthEnderX]

Techniques to bind the kyubi, with those massive Red Tori like things pinning it to the ground.
I know this was a flashback, I did think it was strange at the time, but now I still wonder about these techniques.
The round lock is clearly a spell from his father and seems fairly easy to use. The pining ones, I wonder.

Naruto can do that because he has the key to the seal remember.

The whole thing with the frog that's a scroll that was inside Naruto. Then they transferred the key from the scroll to Naruto's arm.

So he can basically open and close the lock at will, which, in his head, allows him to trap Kyuubi in those gates whenever he wants.

The high level technique here was his father building the lock. Opening and closing the lock when you have the key doesn't require any special skill.

Just the way Kyuubi said it. Made it sound like Naruto was capable of something that wasnt explained or brought about until now. Maybe the creator is hinting at something.

At this point, I wouldn't be surprised if Naruto CAN get the Rinnegan, since the other person to have it, Nagato, was also an Uzumaki.

Then, between having the Rinnegan, being a Jinchuuriki, and knowing Sage Arts, he's probably well on his way to becoming the next SotSP. Which is probably the end point of the series.

The villains of the series are trying to reach that point by design, but Naruto is doing it by accident, probably because he's meant to.
