I f the person who sasuke and co are gonna meet is uchiha then i have a feeling it...

[True Power Incarnate 2012]

....could be Kagami Uchiha. The reason i say this is because he's an uchiha and seeing as he was part of team tobirama(which included hiruzen sarutobi,torifu akimichi,homura,koharu,danzo and kagami) in the war which happened after hashirama's death meaning at the time of the 2nd war tobirama was hokage and hiruzen was trained by by both hashirama and tobirama before hashirama had his battle with madara i'm guessing that kagmi must have been born around the time or not long after konoha was founded meaning that he would have known what the uchiha were going through etc and so i'm guessing seeing as we do not yet know how kagami died i think it's possible that he may still be alive and obviously old and wise and he's be around the same age as hiruzen and danzo so i don't see why he wouldn't know alot,you never know kagami uchiha could be in some sort of hideout like madara cause everyone thought/believed madara was defeated/killed and it turned out he didn't and had infact survived and was an old and wrinkly man in a hideout but anywayz this is just my opinion.

Plausible very plausible.

Don't know, don't care, i can't wait until sasuke get his new power :3

Oh and before i forget...orochimaru probably knows kagami is alive and knows where he is and it wouldn't suprise me if orochimaru and kagami worked togther at some point like he did with danzo.

What is it with people and their obsession with Kagami...

 

[Jellal Fernandes]

Wow...No Periods in the middle in your wall of text...How can it be him? He knows nothing. Maybe shisui but Kagami?
He was mentioned once i believe and isn't even important to the story..

Could be possible, for some reason the new chapter shows Torifu Akimichi while Choji is holding the Juubi's arms. He is like the far right guy.
