Gundam: G no Reconguista Movie IV - Gekitou ni Sakebu Ai

The Megafauna leaves Earth's sphere for Venus Globe, the distant source of the Photon Batteries on which human civilization depends. There, Bellri and Aida encounter the G-IT Corps, whose Reconguista plan aims to return to Earth and reshape it by force. Their meeting with the leader of Venus Globe makes it clear that the energy crisis is inseparable from the larger question of humanity's future and its place between Earth and space.

There is little time for a peaceful answer. Conflict among the Amerian forces, Towasanga, and the Capital Army erupts again, expanding into a three-sided war. As the battles spread, Bellri tries to use the G-Self to stop the fighting rather than simply win for one side, even if that choice makes him a target for all of them.
