What's going on right now in my master's mind is that apparently the only country that is left for the Rebel Academy, said to be Pan-Asian anime-oriented willing to end all international disputes on the continent single-handedly it wants was... wait a minute... something is off onto my memory for a moment.
Japan...
However... it was occupied by the famous Vocaloid goddess everyone on this planet knows to this day enjoying peacetime save for Ryukyu, an independent archipelago and is the only influential trade partner. It took only a week or so for such a ravaged country to seize nearly all of Asia after being devastated several times from civil conflict, because there is barely anyone living around except for an A.I. populace controlled by very few humans, the G51 Group, making the takeovers very straightforward. If he takes that last country, the whole continent in terms of manpower under the Academy's control compared to these islands would be just enough to rival the combined Western countries. I am no politics expert for that matter.
