'hokay, from the top then.
In description, I'd like a little more. Not too much, but you want us to be able to picture the character in our heads, just based on your description. How long is his hair? What shape are his eyes? What degree of white is his skin (tanned, pale, etc.)? In the distinguishing features, how did he inflict the scar? (Don't add that in, just explain here. Yamataians don't scar unless they go out of their way to, so unless he specifically tried to scar, he just would've healed.)
The history looks fine, imo.
In the skills, I would add the boilerplate anyway. The idea is that Fort Ready is advanced school, not basic training. The base skills are reviewed and improved upon, not taught so much.
Then you need to add the salary in. I believe it is 50 KS for a Santo Hei, but I may be wrong.
Overall, pretty solid character, well suited to come into Fort Ready.
