Is it possible to bring back Nagato (Pain) using Edo-Tensei?


During Nagato's last fight with Itachi, Bee, and Naruto, Itachi pierced him
with his Totsuka sword.

As per the Naruto wikia page on
[Totsuka](http://naruto.wikia.com/wiki/Sword_of_Totsuka),

> It is an ethereal weapon with an enchanted blade capable of sealing anything
> it pierces.Those who are stabbed by the sword are drawn into the jar and
> trapped in a genjutsu-like "world of drunken dreams" for all eternity.

My question is, can those who were sealed by the Totsuka sword be brought back
by Edo-Tensei?

Does it seal the soul permanantly like
[Shinigami](http://naruto.wikia.com/wiki/Dead_Demon_Consuming_Seal)?

The same question goes for
[Benihisago](http://naruto.wikia.com/wiki/Benihisago) as well.




My theory:

Sealing 'someone' doesn't mean that they are going to seal the soul of that
'someone'. It is not explicitly mentioned that the Totsuka Sword includes the
soul up to the extent like the Shinigami.

The body can be remained in the "world of drunken dreams" but the soul _can
be_ released. Edo-tensei only requires a body of a living person as a vessel,
then a deceased person's soul and bound to it. So it is possible that a person
struck by the Totsuka Sword _can be_ brought back by Edo-Tensei.

Update:

As per Kaguya Otsutsuki about Benihisago, It seals the soul as well. Once
sucked in, releasing Edo-Tensei won't release the person. Its mentioned here
[Benihisago](http://naruto.wikia.com/wiki/Benihisago).
