1. Personality: Blunt, kind, stubborn, and harsh do not really mix together. A little more detail would be good here, like when she's going to be blunt/ harsh, or when she's going to be kind. You can't really be both at the same time.
Also, what do you mean by "Normal"? As you're not assigned to a plotship yet, you might want to save that for a bit. If you mean more reserved and rational than most, then put that. Normality is, after all, completely relative.
2. Uuuh... Nepleslian Separatist colonies? I don't think there are any, save Kennewes, although that's A. Not in the UOC and B. Under occupation by the Nepleslian military.
3. The history is very sparse, and doesn't really make sense given the timeline, but that can be forgiven since you're new. Quick history lesson:
The United Outer Colonies broke off of Yamatai in early YE 30, following a fair amount of political unrest all over the sector. Prior to that, they were under the control of the Yamataian 5th Expeditionary Fleet. In fact, Tio is the son of that fleet's former Commanding Officer, Katsuko, who was at that time Empress of the YSE.
The area wasn't colonized prior to YE 29, when the 5th XF was forced to move there after their old headquarters at Taiie was destroyed by the Mishhuvurthyar. Also, the colonies were all Yamataian holdings. Nepleslia didn't really have jack to do with them before they broke off, aside from some light political hand-shaking between pre-Empress Katsuko and Robert Davis.
Edit: S'more 'bout skillz
4. Humanities:
While I'm not actually a member of one of those fields, I do aspire to be, and I know that it's a ridiculous amount of information to teach oneself, especially if the person in question isn't even 20 years old, and if doesn't make much sense if they believe higher education is little more than a waste.
5. Communication:
I'd suggest taking out the sentence about her being eloquent and convincing. That's up to who's hearing her to decide. At least that's my opinion. I'll leave final verdict on that to the Dosh-meister.
6. Leadership:
Use of this skill for brand new players is often vocally discouraged on general principle: They're bottom-rung enlisted folk. How'd they pick up strong leadership skills? However, your skill description has a little more wrong than that with it.
For one thing, you're multi-skilling, putting numerous skills or trade knowledge under a single skill heading. You have diplomacy, intelligence gathering, command, and I think one or two others listed in there. How exactly would an average teenager, barring extensive training, which she doesn't have, learn all this stuff?
Also, the last bit about people being inclined to agree with her needs to go. Once again, you're not controlling other people in the setting; other players are. It's up to them if they agree with her or not.
