But there's some thing in her past that just makes her umm unique. You see, she comes from a long line of devil hunters.Many female members of the Mano family have been mamono hunters throughout history (they fight evil spirits, demons, cooties..name it). Well enter Yohko, she's the 108th generation mamono hunter. One day she's at the public pool, when she's attacked underwater by a demon. As she struggles for escape a burst of power come from her soul freeing her from the evil beastie. Later, she learns that she comes from a long line of mamono "devil" hunters. So begins the journey.....
