Sayaka tells Hikaru to go to the ground level with Daisuke and the Scarlet Mobile to search for survivors to which Hikaru complies with a sigh.

Downtown, Maria is saddened by Duke's death as he was her only friend. Thinking angrily about the Mazinger Angels, Maria encounters a group of thugs who Maria leads to an alley so that she can vent her anger out on them, easily defeating them due to her precognition and telekinesis.

At HQ, the Angels recount the incident with witness reports talking about Gorgon and his tiger as the perpetrators to the attack on Tokyo and the theft of Minerva. As Prof. Nonaka ponders on what to do, Hikaru brings up the fact on how there is a limit to move Minerva which might leave an opening.

Gorgon has Minerva X destroy parts of the city with its Rocket Punch. As Gorgon gloats, Hikaru tracks the brainwaves giving Sayaka Gorgon's location. As Aphrodite A and Venus A confront Gorgon ordering him to surrender Minerva, Gorgon laughs as he has it attack Aphrodite. After its forearms return, Jun notes how different it looks from the first time, to which Hikaru reveals that it was Minerva's alternate Sirene Mode.
