Shindo is a negotiator with the Japanese government, highly renowned for his skill and dedication to the job. Just before he's scheduled to go on a month long break, he's given the task of buying out a plating factory to convert to a multi-use building. The terms of the buyout are excellent, and the owner of the factory is very interested. But there's more to the deal that meets the eye, and Shindo goes the extra mile to ensure that both parties to the negotiation get what they really want.
A huge, 2 kilometer cube appears in the middle of Haneda airport. A passenger plane is absorbed inside it, and no one knows if the passengers are dead or alive. The Japanese government convenes an emergency meeting to deal with this unexpected event, and tries various things to learn about the cube, which it names "Kado". But when even the most powerful weapons fail, what's left for the people of Japan to do?
The UN Security Council is greatly concerned by the Japanese government's possession of the Wam, sources of limitless energy. They demand that all Wam be turned over to them, and promise that noncomplainance will be met with potential military action. But Yaha-kui zaShunina wants all humanity to have the Wam, and does not want its use to be restricted to only a few governments. He comes up with an alternate plan...
The last of the passengers are leaving the inside of the giant Kado cube, and it's time for the next step: moving the cube itself to a new location away from Haneda airport. Shindo takes the lead in organizing the project, leading Tsukai to ask how long it's been since he slept. He can't remember. This is the next step of the anisotropic's plan.
After the Wam, zaShunina reveals his second invention: A device that allows humans to go without sleep. The CEO of SETTEN, the world's largest internet company, with assets in the hundreds of billions of dollars, wants to be involved in the process. Does he just want his company to have a piece of the pie, or does he have other motives?
Shindo takes a break from dealing with the anisotropic to go around with Tsukai, who wants to dissuade him from helping the anisotropic. He meets her family, and travels on a boat with her. She wants human dignity to be protected, and tells him that zaShunina is a threat to the universe that she loves.
