"Stop your evil deeds and take the right path!" That is the creed of Youko Tama and her younger step brother, Jinka Sendou. The two demon siblings travel the country to stop the deeds of all evil doers, along with a scaredy-cat swordsman they picked up along the way, Hyoudou Shinsuke. During their travels, they will come across a monk organization with more than suspicious methods and they'll soon be at war.
