Japanese government negotiator Koujirou Shindou has been absorbed into a giant 2km long cube known as Kado. Inside, he meets a being called Yaha-kui zaShunina, who seems to possess powers beyond humanity's ability to comprehend. Who is this being, and what are his plans for humanity? Shindou agrees to become this creature's representative as it begins its negotiations with the Japanese government.

The world's governments are demanding the Wam be handed over immediately. An American carrier strike force has left Yokosuka port. Economic sanctions are in place. The Japanese government must either hand over the Wam and give up a source of free, infinite energy, or be ready to fight the entire world. Shindou, however, offers the Prime Minister a third option...

To stop Yahakui-zashunina's plan, Shindo is hidden in an isolated pocket dimension. There he needs to come up with a way to defeat an omnipotent being.
