Kijimutan tells the story of Yuna, a young samurai woman seeking to feed her own ambitions as well as to fulfill her own sense of self. As Yuna and her faithful friend, Musashi, go on their journey, they come face to face with the Shouki, the evil spirits seeking to destroy the very hearts of the people. Faced with the possibility that there might be an enemy within every person they encounter, the two warriors will have to struggle in order to succeed. The Shouki may be a great threat, but the greatest peril to their quest might lie within the heart of Yuna herself�
