Vonai-Rya'ka,
My fondest good tidings to you and yours. Things indeed are well in the galaxy, much more so than they have been in years past.
As much as I wish to answer your question with immediacy, I need more information about the status of the sisters you have under your care.
If they are Nekovalkyrja whom the NMX created, their trepidation is well understood. What they know of their sisters likely shakes out to bent truths and outright lies. Yamatai's military first would debrief them, but given the end of the war, the process likely would not be a long one. It also depends on the individual's rank and responsibility within the NMX.
After the debrief, they become wards of Yamatai's imperial government. They would receive the same living necessities as the rest of our people receive, including school and job training. Once they are on their feet, they are let go.
If they originally are of Yamataian heritage and remain fearful of their government, then we must ask for their return. The likely psychological damage done to them at the hands of the NMX must not only be repaired, but understood for the sake of future sisters who still might come under its effects.

Premier to the EMPRESS HIMIKO,
