Since the ancient times, the Kannagi priestesses have used their swords, or Okatana, to exorcise the creatures known as Aratama that brought chaos upon the world of man. These maidens were known as Tojis. They are a special task force within the police. They are allowed to have their Okatana on their person because they are government officials, but they mostly consist of middle school and high school girls who go to one of five training schools throughout the country. Though they mostly live normal school lives, if they are given a mission, they take their Okatana and unleash their powers, fighting to protect the people. This spring, the top Tojis from five schools across the country have been gathered for a customary tournament where they will use their abilities and fight for the top position. As the many Tojis trained and prepared for the upcoming tournament, there was one girl who was even more determined than the others on improving her swordsmanship. What lies before the end of her Okatana?
