Naruto X Sasuke

There are two common labels for the pairing of Naruto and Sasuke from Naruto. The first is SasuNaru where Sasuke is the seme, and NaruSasu where Sasuke is the uke.

It is quite a popular pairing but the former (SasuNaru) is more common than the latter. It is based on the friendship and bonds the characters have formed throughout the manga/anime - and draws on moments between the characters, and the fact that Naruto is "the only one who can change Sasuke".
