Honestly, I think Shino would make the best friend of the bunch. He doesn't try too hard, but he also maintains friendships, not very well admittedly due to his overall flair (or lack thereof). He's also just a smart guy, so it'd be nice to hang out with him.

Shino Aburame

Interestingly all these are characters that i wish we saw some more stuff out of them still regardless at least if an enemy attacks you all hose people know how to fight and are not stupid( btw why do i find omni to be the black naruto and darui and yes i know not listed to be the black shikamaru)?

Omoi seems to be cool.
