Jun'ichi Nagase attends a prestigious high school. He has the nickname Geno Killer since he was rebellious in middle school. This is used, inadvertently, to help a girl named Yuuhi Katagiri from trouble. She later transfers to his school, and in order to protect Yuuhi from danger, Jun'ichi is forced to kiss her. Not understanding what happened, she screams at him. Subsequently, it turns out that Yuuhi is his fiancé as arranged by their parents. Their parents discuss the matter and order them to go out together for a month to restore their relationship. If their relationship does not get better, the engagement will then be canceled.

Since ancient times, shrine maidens who wield swords have been exorcising "aratama," strange existences that threaten the human world. These young women who wear school uniforms and a sword are called "Toji," and they serve as an official unit within the police force as a "special religious service police squad." The government authorizes the Toji to wear swords and serve as government officials, and the government has set up five schools throughout the country for the girls to attend. The girls live ordinary school lives, while occasionally performing their duties, wielding their swords and using various powers to fight and protect the people. (Source: Anime News Network, edited)

Makoto Ito rides the train to and from school every day. However, at the beginning of his second term, he falls in love with a beautiful girl that also rides the train. Unfortunately, she barely knows of his existence. Her name is Kotonoha Katsura, and though they attend the same school, they are not in the same class. In an attempt to catch her eye, Makoto enlists the aid of a close female friend of his: Sekai Saionji. She helps him, despite the fact that she—unbeknownst to Makoto—is in love with him. Thus the three are bound in a love triangle of life-changing proportions. (Source: Anime News Network)

Yuuki Ashikaga is a high school freshman in his second semester at Sakakino Academy, who from his regular visits to the school library, grows enamored by Kotonoha Katsura, a fellow classman who comes by to read. Despite already having a boyfriend, she genuinely reciprocates his interest. However things get complicated when, following a brief encounter, his sister, Chie Ashikaga, introduces him to Roka Kitsuregawa, an acquaintance who also becomes infatuated with him. Out of jealous spite for her rival, Roka attempts to dissuade Yuuki by claiming to like Makoto Itou, another schoolmate. Her lie dramatically backfires, as Yuuki, aware that Makoto is Kotonoha's boyfriend, goes to ask her about the affair.
