Brain Powerd - S01

In the near future, much of the Earth has been swallowed by the sea or devastated by earthquakes. At the heart of this chaos is Orphan-a mysterious being that may or may not be responsible for the disasters. Orphan seeks to raise a sunken ship from the ocean depths, an act that would wipe out all humans except those who serve it. Orphan's agents control strange mecha called Grand Cheres, scouring the world for massive, elusive disks that appear without warning. These disks tear through the skies before crashing violently, leaving destruction in their wake. When one nearly kills a girl named Hime, a Brain Powerd-a living mecha resembling but distinct from the Grand Cheres-emerges from the dying disk. Hime bonds with the Brain Powerd in a symbiotic partnership and joins an international group fighting to stop Orphan. If they can't prevent its plans, they’ll at least try to save what remains of humanity.
