User blog comment:GokūBlack10/The Sage of Six Paths and the Ten-Tails; a Naruto Tensei idea/@comment-3090940-20101214024419

im from monster hunter wiki and i think it is good go naruto. ( off note : wouldn't it be crazy if below madara's chamber there was a ash black man who had half of the ten tails inside his body and madara could not handle it so he kept him in holding and the only way he is being controlled is thru being constantly put to sleep (random sage of six path's brother)that would be a massive twist.)
