When a remote controlled boomer working on n undersea project suddenly takes off and starts heading for Tokyo, AD Police officers Leon and Daley decide to investigate just who or what could be motivating it. Meanwhile, Sylia begins conducting her own investigation, but will she be able to do anything about the boomer when the hardsuits are still undergoing repairs?

Now fused with the upper levels of Genom Tower, Galatea takes off into space, heading for the giant space umbrella that will furnish her with the power to spread the rogue boomer phenomenon throughout the entire world! Now Priss, Linna and Nene must somehow find a way to get there first- because humanity's continued survival may well depend on it!
