Kyouko Taisei (強硬体制, lit; Unyielding Order) is a samurai who hails from the Land of Iron and is the mother of Kiritsu Taisei. One of the few female samurai that consist of the Land of Iron's forces, Kyouko is perhaps one of the best. She has never been defeated in sword to sword combat and her other skills in combat benefit her perfectly, all synced together with her kenjutsu. Like her son, she is deaf, something Kiritsu inherited from her. She is often seen alongside Hangaku, an old friend of hers and a trustworthy ally.
