As the name suggests, these practicing warriors can combat and kill yōkai despite lacking the spiritual powers of monks and priests, due to many years of training, and the use of special weapons or equipment made to combat demons. Due to their strength, specialized weapons and skills, they are mistaken by some people to be ninjas. Something that is furthered emphasized by the fact their overall combat attire resembles a ninja outfit with armor and some bears their own customization like Sango's having a pink theme color.
