The Alexandria destroys the AEUG's moon base, but the Argama and the new AEUG ship Radish escape and head to Earth. The AEUG ships pick up a distress call from Bright Noa's shuttle, currently under attack from a pilot named Paptimus Scirocco.

Henken promotes Bright to Captain of the Argama and leaves for the Moon as the AEUG fleet heads for Earth. Scirocco believes he can stop the AEUG at Earth, and he, Jerid, and Kacricon attack Emma, Kamille, and Quattro as they descend through the atmosphere as the danger of burning up completely becomes more real.

Amuro offers himself as an exchange for Mirai, and Kamille helps hold off the attack during the rescue attempt.

Kamille learns that Four doesn't have any memories and they share a kiss. The Audhumla prepares to leave Hong Kong while Ben Wooder attempts to pilot the Psyco Gundam. Four takes over piloting and Kamille and Amuro fight against her.

Hayato plans to attack the Titans' base in New Guinea to steal a shuttle for Kamille and Amuro to return to space, as the Argama has returned to Earth orbit. The Psyco Gundam continues in its pursuit of the Audhumla, but Four soon turns on Wooder and the Sudori to help Kamille return to space.

Wong Lee boards the Zeon ship Gwadan and Haman Karn introduces him to the current leader of the Zeon, Mineva Lao Zabi, the last surviving Zabi. Char's grudge against the Zabis doesn't help the AEUG's deal, and Scirocco plans his move for a deal with Zeon.
