funny but, if he needs kumai to leave the other dimension
that means he still has to be wearing 1 sharingan as he arrives back to the normal dimension
meaning he will have to have the rinnegan in his hand or pocket or whatever lol
now if naruto was alone i could see him having a chance to implant it being as naruto is stupid
but Sasuke and Kakashi are another story, they are not going to let him implant
i think Madara will show up with both rinne in though because its no way they will let him implant
further adding to Madara breaking like every single rule lol
