Koujirou Shindou, the Cabinet Office Director-General for Policy Planning, is at Haneda Airport on a business trip. While the plane is on the runway, a giant structure suddenly appears out of nowhere. The aircraft carrying Shindou and 251 passengers is drawn undamaged inside the massive structure. After everyone disembarks, a man who appears to be an ordinary human being shows up. He assures the passengers that they are not in any danger. Shindou asks him to identify himself and explain the situation. Then, the exterior of the structure is displayed on a large screen, and at the same time, every passenger's cell phone starts ringing simultaneously. On each screen is a message from this man addressed to every citizen of Japan: "I, Yaha-kui zaShunina, hereby notify you that I am going to intervene in Japan's internal affairs." What is this young man's goal? And will Shindou manage to become an intermediary between Japan and the Anisotorons...?
