Koudoutai

Koudoutai are ancient and secretive order that few know exist. They wield mystical armor created by the founder of the group, Tenmaru Seiougami. The ruling of the group is hereditary much like a kingdom of sorts, but the only one who ever challenged the royal family's rule ended up being exiled. He challenged how appropriate the King armor go to a technically future Queen, but as the royal family only her and no sons before they died there was legal other candidate. The young queen in the King armor was powerful yes but still young couldn't control her power so her guards used their own combined power to exile the Traitor from their homeland or in other words, the place known to them as the Seiniwa(Star Garden). To them it's sacred land, but they aren't a religious group.
