Now, the world has united in the hopes of regaining their home. The scientist and soldiers in Japan have to work carefully to avoid bringing the world to war. The Mighty Tengi has seen to it that there is peace between mankind and the kaiju, but her reign teeters on the brink of destruction.

World leaders and secret organizations are patient for their newest scientist, Dr. Scott Macy, to discover the solution to their problems, a giant soldier. Then the addition of the Mu society to the surface world leaves a trail of destruction. The fight to claim the Earth begins here.
