Photon batteries are an energy source created to save the resource-depleted Earth. Bellri Zenam, Aida Surugan, and their comrades have left the Earth Sphere to head for the source of these energy devices that cannot be manufactured on Earth. Now the Megafauna finally reaches its destination, the Venus Globe in the inner solar system. After battling the G-IT Corps, which plans to return to Earth in a Reconguista operation, Aida has an opportunity to meet with President La Gu of the Hermes Foundation, the organization that controls the production and supply of the photon batteries.
