Can someone explain this to me. I saw at the conclusion of the fight between Orochimaru and Sarutobi that Enma took the Kusunagi sword with him after removing it from Sarutobi. Then I saw during the fight between Oro and Naruto four tails he again used this sword. Then Sasuke used the same sword during the fight with naruto and sakura. Can someone explain, was this ever mentioned. Perhaps Oro summons it from where ever it is, however it seems he more less removes it from his body. Anyone know the answer.
