I have two main friendship pairings.

1. NarutoxGaara

2. NarutoxShikamaru

I do also treasure the NarutoxSasuke friendship, but it's not as high on my list. I think that Naruto and Gaara have a much more genuine friendship, not to discount what the other friendships have. It just appeals to me more. I always thought that Naruto and Shikamaru's friendship was very unique and interesting. I love the Shikamaru's witty banter and the way Naruto reacts to the things he says.
