When Priss is trapped in a cafe with a rogue boomer that is too much for the AD Police to handle, it falls to Linna and Nene to tackle the monster. But with both Linna and her hardsuit untested in battle, can the Knight Sabers hope to emerge victorious in this engagement?

With Nene stuck at work and Linna out of town, Priss is left to deal with a rogue boomer on her own- not easy when you're running low on power. Meanwhile, Linna realises she must decide what is most important to her before she can make a decision about which path her future shouls take.

From the heights of Genom Tower, Galatea has reached out through the Dragon Line and made Tokyo her own. But when Galatea goes one step further and starts absorbing Macky's mind as well, the Knight Sabers know they can wait no longer. Donning their hardsuits, Sylia, Priss, Linna and Nene must penetrate the tower itself and force a showdown with Galatea herself if they are to save the city and the people they love.

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!
