Yeah lol I don't get it how no one did the
connection with Karin's hair being red and we
cleary got info that the Uzumakis got red hair
lol...and wtf Dragon Sage ... REALLY??? come on...
why did Naruto have to get a crappy Frog sage and
Kabuto got the dragon come on!
Basically for every summon they must come from
somewhere right? So if you reverse summoned you
end up in that place where they come from and
thats where you can learn to become a sage. So
there could be as much sages as there is summons
for a species e.g Bird Sage Tiger Sage its
possible. Also they have to make more
uzumakis come out I mean it would be wierd if
naruto was the only one btw I would like to know
more about narutos dad side.
most probably not...some
of Kabuto's action aren't
supervised/without permission of Orochimaru.
Remember that Orochimaru didn't noticed
Kabuto WAS a spy of Sasori until he was released
because of Sasori's death.
