Summary
With the Underground Empire's resources under their control, the Mycenae Empire lead by Great General of Darkness-ko prepares to fight the Robot Girls. Meanwhile, at the Photon Power Laboratory, Team Z reads an article that reveals that the Underground Empire went bankrupt. Team G comes in and reveals that Baron Ashura and her main Mechanical Beast Girls were seen in town. In need of action, Z-chan dashes off to find the depressed group looking for a new job as they have no means to support themselves anymore.

Archduke Gorgon and General Juuma then appear to confront the Robot Girls. While Team Z is ready for a fight, the Great General steps in and causes Team Z an uneasy feeling. Ashura and her Mechanical Beast Girls then step in front of the Robot Girls to fight claiming that they are the only ones allowed to defeat the Robot Girls. However, they are quickly swatted away into the distance. Great General then takes the Photonic Energy from the lab while Team Z tries to fight back but their attacks have no effect. Even help from Team G does nothing.

Ashura and the Mechanical Beast Girls have landed in their old base while feeling hopeless that they can't do anything. Just then someone steps in to tell them the way to the battle. The Robot Girls have been crucified and were about to be executed by Great General until Robot Girls Team T came with Baron Ashura for back up. Bara-tan however throws Ashura off for insulting her. Ashura then uses the growth ray from chapter 4 to make Z-chan grow to gigantic size, even bigger than Great General. Ashura explains Z-chan's heightened power as she crashes to the ground.

The Mycenae Empire, even Great General look concerned. Dr. Hell then berates Ashura for helping an enemy on a monitor on the ray gun explaining that Z-chan's battle suit has greatly enhanced her power now that it has grown in size. Great General even looks scared and begs for mercy until Z-chan unleashes a Rocket Punch that destroys Great General. Mycenae-tan is then revealed and attempts to beg for mercy long enough to escape. However, as Z-chan shrinks back down she notices that Ashura had darted off stating they were enemies again. Team Z is just happy that things are back to normal and is prepared to fight any threat.
