The 1st Rapture Invasion. The disaster descended suddenly without warning.

Without any precursor, unidentified mechanical lifeforms, the Raptures, appeared through the orbital elevator.

The Raptures, with whom negotiation was impossible, began by destroying shuttle launch pads in various places and committed indiscriminate massacres against humanity, ruthlessly destroying the civilization mankind had built.

Human technology was meaningless before the endless onslaught, and humanity was literally just being trampled. Day by day, they trembled in fear, praying for survival, just hoping to stay alive.

In the early stages of the disaster, instead of covering it up, the leaders of each nation immediately deployed military forces. However, the Raptures evolved rapidly in response to human weaponry, and not only were they unscratched by live ammunition, but even mobilizing anti-ship missiles and nuclear weapons proved useless. Eventually, the world leaders had no choice but to reveal the reality of the situation.

Sensing the gravity of the situation, the high-ranking officials of each nation evacuated people to shelters and formed the Human United Forces to resist the Raptures' ruthless massacre. However, the best military power of humanity at the time could not inflict any damage on the Raptures' overwhelming numbers, weaponry, and durability. Literally, they were unilaterally trampled and ruthlessly slaughtered.

As the war situation continued to tilt completely toward the Raptures and despair loomed over humanity, the giant corporations moved.

The Big Three companies: Elysion, Missilis, and Tetra. They pooled their technology and capital to develop and deploy the anti-Rapture decisive humanoid weapon "Nikke," starting with Liliweiss. Simultaneously, they found suitable candidates worldwide to create Nikkes of the 'Fairy Tale Model,' minor copy versions of Liliweiss, and gathered them to establish the Goddess Squad.

The Goddess Squad, established in this way, performed brilliantly, completing 20 operations 100% within two weeks. They came to be called the symbol of hope for the Human United Forces and the Goddesses of Victory, becoming the sole lifeline for humanity, which was literally on the verge of annihilation.

People moved by their exploits began to appear one by one, volunteering for Nikke experiments, saying they also wanted to become Nikkes and save the world.

Even today, the members of the Goddess Squad, the beautiful Goddesses of Victory, are fighting for the survival of humanity and the reclamation of the surface.
