Goddess of Victory: Pandora's Box

(This is a crossover between Mobile Suit Gundam Unicorn and Goddess of Victory: Nikke. I do not own any story and characters from the respective franchises. The story will be loosely based on the Nikke storyline and Gundam Universal Century lore)

After the Heretic Modernia (Marian) was rescued by the Counters squad during a mission on the surface, she was sent to be treated for the injuries she had sustained in her previous battle. A scan of her brain showed an encrypted coordinates leading to an artifact dubbed the "Pandora's Box", which had the power to topple the Central Government. With the knowledge the Raptures, humanity's sworn enemy, would want the Box in their plan to eradicate the humans, its a race against the clock to retrieve the enigmatic box.

What lies within the Pandora's Box? Will Marian and the Counters squad find the box in this journey that will shed blood, sweat and tears?
