Summary
Being unhappy with the fact Koji and Misato are out on a date together, Sayaka sends Boss, Nuke and Mucha to spy on them for her. The three are attacked by the Mechanical Beast Harpia Π7 on their way to Koji and Misato, but manage to escape unharmed. Back at the Photon Power Laboratory, the radars detect Harpia prompting Dr. Yumi to send Sayaka to fight the Mechanical Beast. The fight doesn't last long as Harpia backs away after hitting Aphrodite A a few times. Boss and the others find Koji teaching Misato to ride a motorcycle. After reporting the fact to Sayaka, they inform them about the Mechanical Beast flying around. Unfortunately, before Koji can return to the Photon Power Laboratory, Misato loses control and crashes into him. Despite his injuries, Koji goes back to get Mazinger Z.

Realizing Koji is condition, Dr. Yumi prevents him sorting and sends Nuke and Mucha in Boss Borot instead. The two of them encounter Archduke Gorgon who easily gains the upper hand, but are saved by Aphrodite A's intervention. Gorgon leaves shortly after to head to the Photon Power Laboratory.

Harpia arrives and attacks Aphrodite A and Borot once again. Boss joins them and assumes control over Borot, but even so there isn't much they can do against the flying Ghost Mechanical Beast. After considerably damaging Aphrodite A, Harpia flies away once again.

Now wanting Archduke Gorgon to single-handedly gain all the glory for defeating Mazinger Z, Dr. Hell orders Baron Ashura and his Iron Masks to join the fight. Realizing that enemy reinforcements are on their way, Dr. Yumi calls Boss Borot and Aphrodite A back, however, Sayaka does not wish to return. She realizes Aphrodite A will problably be destroyed if she keeps fighting and refuses to comply with her father's orders arguing they wouldn't be in this situation if Koji and Misato didn't hurt themselves earlier. Back at the Photon Power Laboratory, Harpia manages to break through the barrier. Dr. Yumi's about to surrender when Koji finally boards Mazinger Z. He easily dispatches the Iron Masks' tanks, but struggles against the Mechanical Beast, Meanwhile, Dr. Yumi convinces Sayaka to come back to fight. As Koji's about to lose, Aphrodite A arrives and shields Mazinger Z from Harpia's attack getting destroyed in the process. Koji then defeats the Mechanical Beast.

Although Sayaka doesn't resent Koji for what happened, she asks him to apologize to Aphrodite A before sending her away. Koji agrees and uses Mazinger Z's Rust Hurricane to turn Aphrodite A into dust and send her far away.
