Agreed Guys! :>
Naruto isn't ready yet.
Danzo would probably get killed by sasuke
so, the best option is Kakashi or Tsuande.
-Tsuande i think would regain her title back and she'd be fighting Madara. (we'll she more of her as a senju, hokage, & sannin)
) -- as someone above said, she has an expirience with the last 3rd ninja war.
- So if not, kakashi's there to get the title! :>
