I think it's a really interesting approach. Her body is frail, but she compensates with a powerful mental ability. Plus, she has the bodyguard to assist with physical tasks. Quite interesting indeed.
Although, The Order functions more as a militaristic group. The Bureau thing doesn't make much sense. If anything, change it to say that she's a decorated officer in The Order. If you'd like, she could be one of the Emperor's hand picked agents.
I do like how he was speaking to the guards though, that is actually fairly accurate to how I imagine some of the higher ranking officers to behave. The Order's Philosophies are primarily about strength and usefulness, and tend to look down on those who are deemed beneath them. Overall, I think its a good post. So, good job. ^_^
