If edo-Tobirama is sensing edo-Madara , Madara is sensing "fun" or the edo-kages .
Given the huge area of Naruto's sensing ability ( a little country ), before the fight with Obito , and the huge power-up he got during this fight , I'm not surprised if Naruto was sensing them from their rebirth.
this wud be funny.
minato hasnt yet seen naruto.
naruto and sakura are close to each other so difficult to tell which chakra is which
then minato mistakes sakura for being naruto, lets face it she is flat and only boys have forehead that big.!!
minato(looking at sakura): hae naruto looks like you dyed your pink, but pink seriously.!! you arent that kinda guy are you??
sakura(annoyed): channaro.!! (beats naruto to a pulp)
now i feel alot better.
btw yondaime he is naruto.
