The year is 1863 as the tumultuous samurai era is coming to an end, Japan is split between the pro-shogunate and anti-shogunate factions. The fate of the world is threatened as an army of historical revisionists are sent from the future to alter the course of history. In order to bring these forces down and protect the real history, two sword warriors, spirits who are swords brought to life by Saniwa (sage), rush to Edo. The polite and thoughtful Horikawa Kunihiro and the short tempered yet skillful Izuminokami Kanesada, who served the same master, confront the invading army along with a lively gang of other warriors including Mutsunokami Yoshiyuki, Yagen Toushirou, Tombokiri, and Tsurumaru Kuninaga.

As the fate of history lies in these hero's hands, what meets the blade is yet to be uncovered...

There's an evil creature called Aratama that attacks people, and a group of Miko has been exorcising those creatures using swords since olden times. Those who wear uniforms and swords are called Toji, who are officially called Tokubetsu Saishi Kitoutai (Special Ritual Maneuver Team) in the police association. They are officially approved to wield the swords by the government officials. The government has established five training schools consisting of junior and senior high levels for the female students to attend. They spend their student life normally, and use special skills with the swords when they're doing missions to protect people. In the spring, these five schools are to take part in a competition. Among the girls who train for the competition, there's a girl who's a bit more passionate than any other girls. Where would the girl with the sword aim?
