Brain Powerd

In the near future, much of the world has been swallowed by the sea or ruined by earthquakes. At the heart of the chaos is a being called Orphan, whose true role in the disasters remains unclear. Orphan seeks to raise a long-buried ship from the ocean depths, an act that would wipe out humanity-except for the few who serve it. Orphan's followers control powerful mecha called Grand Cheres, scouring the globe for enormous flying disks that appear without warning. These disks tear through the land, leaving destruction in their wake. When one such disk nearly kills a girl named Hime, it gives birth to a Brain Powerd-a living mecha distinct from the Grand Cheres. Hime forms a bond with the Brain Powerd and joins an international group fighting to stop Orphan. If they fail, their last hope is to save as many lives as possible before Orphan's plan succeeds.
