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,
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?
The same question goes for Benihisago as well.
