Why raise activity in Kusari.
Have all of its factions unite under the glorious Emperor.
Then with 100% unity you finish that little war you've going on, to see your enemies driven before you and to hear the lamentations of their women, Conan-style. Or actually husbands, seeing as we're talking Kusari-Bretonia. And after that you just conquer more. And more. And again more more more more more. And once that's done we may add some Japan-power in there and we'll get to fight in space with giant morphing mechas, beamswords, Macross-esque missile spam, and all that other fancy stuff. Because it would be GLORIOUS AND AWESOME.
