Zhou Gongjin who was the mastermind of what happened in the "Parasite Doll" incident of "Nine Schools Competition" has fled from Yokohama, to the area of the original ancient magic users group centered around Kyoto also known as the "traditionalists". Since then two months have passed - The "National High School Magic Thesis Competition" will soon be held. This year's Thesis Competition is being held in Kyoto sponsored by the Magic Association and in their conference hall. Tatsuya gets visited by the Kuroba twins who as representatives bring Yotsuba Maya's letter to him. The letter is a request from his aunt saying - "hope your cooperation to capture Zhou Gongjin".
While it is questionable whether it is a "command" rather than a "request", Tatsuya and Miyuki go to Kudou's house as they are in the center as opponents of the "traditionalists". The siblings have an encounter with fate with the "Genius Augmented Magician”. Conspiracy of the ancient city was the stage. The fate that has continued to smolder away in the back of the history of magician development, Tatsuya and Miyuki and his companions are challenged.
