SasuNaru fic

[Guest KonohaKunichi]

In the beginning, Naruto is sent from Konoha for training to try and control Kyuubi, and after a while Sasuke is the only one who notices that he's gone. Naruto congress back like ten years later because he was injured and can't heal himself, but he refuses to tell anyone (except Iruka and Kakashi) he's back. He dyes his hair and goes by some other name until he gets found out, and he ends up fighting with Sasuke at some point to gain control over/fully assimilate Kyuubi's chakra.

Sidenote: Sakura might go a little nuts and have to be locked up, but I'm 95% positive that's a completely different fic where Naruto gets pregnant. There's no mpreg in the fic I'm looking for.

Any help would be super appreciated! Thank you internet!
