One of my really self indulgent au’s is Tobirama, Hashirama, and Madara coming back to life while team 7 are still tiny genin, except Tsunade has become hokage without Sasuke running off
The three of them come to the conclusion that Naruto is Hashirama’s great great great grandchild (“brother, he has the same chakra as you” “where did you get that necklace?” “Granny Tsunade”) and Hashirama is so excited that Sasuke and Naruto are friendly rivals, and Sasuke won’t let his teammates reveal anything to them because he doesn’t trust these 3 suspicious adults so no one tells Hashirama that Naruto’s not actually Tsunade’s grandkid
