I'm not so sure I can really be considered a ninja. I have the speed, but my strength is pretty low. I don't really consider myself a ninja, I just think of myself as an average civillian with super speed.
I'm more likely to run away to avoid any physical contact, and I suppose I'm pretty skilled with long-distance stuff. I can use a bow and arrow, but I would much rather run to avoid wasting arrows. (They're expensive! *sniffle*)
My defensive skills are average, so I can take a couple of hits before I start to wobble.
I have a decent amount of chakra, and sometimes I put it into my arrow to make sure it stays on target and hits hard. (So you can assume that I have control over anything I 'enhance' with my chakra. But that's only with small items like arrows, kunai, and shuriken.)
And, that's about it.
