Seikaisuru Kado: Beyond Information

When a vast cube engulfs an airliner at Haneda Airport, negotiator Koujirou Shindou encounters a visitor beyond anything human diplomacy has prepared him for. Yaha-kui zaShunina emerges from the structure known as Kado and makes Shindou his intermediary with the world outside.

The visitor offers discoveries that could overturn the limits of civilization, beginning with an inexhaustible source of energy. Governments scramble to respond, while Shindou and fellow negotiator Saraka Tsukai confront increasingly difficult questions about the price of progress. What begins as an extraordinary exchange becomes a struggle over whether humanity should follow the future being offered to it.
