Miki Hatori
刃鳥美希
Miki Hatori is Masamori Sumimura's second-in-command in the Night Troop. She is often accompanied by her aide, Higurashi. Though rarely seen early in the story, her role is expanded as she becomes more involved with the kekkaishi (Yoshimori and Tokine in particular). http://kekkaishi.wikia.com/wiki/Miki_Hatori
