what happens

After a short time skip, Kouji and Shiro now live at the Kurogane House and work alongside the Photon Power Lab in the fight against the mechanical beasts. However, friction has been born between Kouji and the Robot Corps, who he finds useless and has no desire to fight beside. Meanwhile Baron Ashura, eager to prove him/herself to Dr. Hell, begins a co-ordinated mechanical beast attack on Tokyo, Osaka and Nagoya. At the same time, three mysterious blonde women arrive at the Kurogane House.
