The serpent hiding in the leaf

What is the deadliest serpent? Naruto Uzumaki that's what! I can't say that's who because that would imply he's human. Naruto Uzumaki is the result of a successful experiment by Orochimaru to make the perfect man-snake hybrid besides himself of course. When he finished the experiment and he tested Naruto he wasn't sure what to expect but it wasn't this. Orochimaru didn't expect that while Naruto took on all the good traits of snakes he also took on the other traits. So what you have here is the most venomous and deadly version of a snake with night vision and optional infrared that is also deaf and mute as well as being dichromatic. Oh, and he can glide short distances. The story timeline is different than normal. Naruto is one year older than Kakashi and is also his team leader up in the ANBU. Naruto is forced to step down from his ANBU assignments to be sensei to a team of genin. Since most children don't know sign language Kakashi who is Naruto's designated translator must come along. Of course, Naruto doesn't have to use sign language he can also whistle and flick his forked tongue. He is analytical and on guard most of the time but still a pretty nice and funny guy if you can understand him. His behavior is closely related to a snake as well. He yawns to gather air particles for smell as well as flick his tongue to smell. He wiggles his head as an indication of him smelling something interesting. When he is highly stressed he will do this erratically. He will often wander like snakes as well. Hell, he even sleeps in an S like shape. His eye color changes when he is ready to shed which yes is something he does but it doesn't take as long as a normal snake. He is also uber-fast.

Long description but yeah. So I did a lot of research on snakes so I know my shit. The pairing is KakaNaru if you couldn't guess. Or NaruKaka I'm not sure yet. Also bad cover I know but I couldn't find anything better.
