so I'm going to go waaaay out on a limb and say that the scroll found and given to orochimaru contains a jutsu that is able to temporarily release not only those who used the death god jutsu but also those who were sealed by it, therefore the ones who know everything would be the past four hokages, which may give us a chance to see hashirama vs madara
Well, here's one theory which I think is
closer to reality. That person they called as one
who knows everything is no other than that white
snake who taught Kabuto to become a sage. Now why
would I say that?
That snake sage, I
think is a sage of the past as opposed to the
elder toad sage, which is a sage of the future.
The toads have someone who has a gift of prophecy
while the snakes have that which has a gift of
history. Thus, his title "The one who knows
I always loved flirting with that idea of
releasing the souls caught in the death god..An
epic jutsu it must be to pull that kind of move.
Yet when I get to the part on "who"
could pull that off... I'm at a loss. Plus,
you can't forget that it would have to be yet
another sacrifice. Unless said person was just
THAT bad ass where he doesn't have to! But
yeah, I was boasting this idea on another blog as
"I could see it happen as a last resort"
Yeah I can't imagine what really will happen
if it turns out that way. I guess it will bring
more epic battle and some explanations to some
unsolved issues about the past. Yet again I
wouldn't want to wait to see Hashirama and
Madara in action. in which case it means someone
will have to perform the "Edo Tensei"
again since Hashirama and Tobirama were already
dead before their souls were sealed with the death
god technique. The only person capable will be Oro
