Story[]
Fio arrives at Marco's office to inform him of an attack by the Amadeus Syndicate, but finds a surprise instead. Tarma comes over and is surprised that Marco has turned fat, and deduces that it must be the new rations that were given out as they are so addictive that "once you eat it, you can't stop".
As a result, Molly is called in to participate in the attack. Perche also comes along to assist.
The Amadeus AI are overwhelmed by the PF reinforcements and the Doctor AI wonders what went wrong. Iron Fortress's AI tells him that they are still learning, so they retreat. Seeing this, several Golden Morden Robots self-destruct in an attempt to take out more PF soldiers. Perche and Molly manage to get most if not all of the soldiers away in time.
Molly runs into Amber and boasts the achievements she did in battle and asks why she is here. Amber tells her that Marco called for her and tells Molly that she has a lot of coins on her and she should spend it soon before walking off, much to Molly's frustration.
