Something descended from the sky above Vatican City.

People prayed, believing God had descended, and the Pope himself came out to bow his head.

It raised its hand.

December 25, 2602, 18:01:24.

Vatican City disappeared from the map.

Nations immediately sent their militaries to stop it, but they were swept away in an instant like fallen leaves in the wind.

Eventually, only after the authorization and use of nuclear weapons was it confirmed to have stopped moving.

A week later, they descended simultaneously from the sky, and countries began to be destroyed one by one, starting with the smaller ones.

Leaders of the world's powers gathered for a meeting. They couldn't keep spamming nuclear weapons every time one of those things descended.

At that moment, one representative raised their hand.

A solution that had been impossible due to ethical issues but was technically feasible—the only remaining solution.

Project Android

Each nation immediately began producing androids, and the tide of war turned in an instant.

November 13, 2615, 11:38.

After 13 years, the war ended abruptly with humanity's victory.

Humanity hailed the androids as Justia, and peace seemed to return quickly.

But a problem arose. What should be done with the Justia?

Justia were now nothing more than white elephants with no use. However, some Justia were active as celebrities, and their popularity was sky-high.

Scrapping them now would destroy public sentiment.

At that moment, someone spoke up.

What if... we used them for war?

In that instant, Justia went from being gods of justice to remaining gods of justice for some, but becoming gods of disaster for others.

Several unsuspecting nations were immediately invaded, and even more Justia began to be produced.

Korea, too, immediately began production of Justia.

Red Velvet, responsible for land-combat Justia.

Ocean Blue, responsible for maritime-combat Justia.
