The release of the edos??

[Killahkels]

Exactly how does the release of the edo tensei work? Im not sure Ive seen Kabuto or Oro release one. If so rep for anyone who can point it out or answer this if the edos are released by their summoners what happens do they A go back to dust or B still have to be sealed/defeated but just lose their ability to regenerate.

If B is true then its possible for Mu, Madara and Itachi to still be walking around after its released.:shrug:

You see them dissapearing and all which remains is the body which was sacrificed for the Edo Tensei.

After Hiruzen sealed away the edo hokages they turned into dust and the bodies of two sound ninjas could be seen so probably this happens too if the jutsu is released and you dont have to seal them after the jutsu is released so A option

So, does that mean recasting Edo Tensei would need new live sacrifices? If so, then Kabuto wouldn't want to release that as it would be hard to look for new bodies to sacrifice, right?
