im almost positive were gonna see the return of kyuubi naruto...
1. Sakura is crying...
2. Konoha was hit by an atom bomb... (may or may not include Ichiraku Ramen...)
3. Naruto is facing down the very person who killed his Sensei and mentor... and almost killed his squad leader/sensei...
4. pain has killed many villagers including Shizune...
if that doesnt turn Naruto into the epitome of demon anger i dont know what will
if he goes kyuubi... we will see more tails than we have seen yet...
and my reasoning is... Kishi purposely had Pain Make a giant crater...
he made the next battlefield so naruto wont kill any friendlies....
now would be a great time for konoha to think about a central lake in the city...
could be nice.... lol
