My character, Hidetaka Kojima is a religious extremist, but in a way different style. He believes he was chosen by the Heavens that said Kusari is corrupted by a cancer and he must purtify every possible threats (this is, Gallics and KNF traitors) to the long-living Kusari traditions and survival. He doesn't really care if the government will be Imperial or Shogunate, as far as it won't be influenced by third parties.
If you were looking for the real life comparison here, think about Yellow Turban Rebellion (2nd Century in China) and short-lived Taoist Sect led by Zhang Jiao.
