“Attention. Currently, the Earth has fallen. We repeat the announcement. Currently, the Earth has fallen.”

“From this moment on, all of humanity is no longer under the protection of national laws.”

“Our government will strive for the safety of its citizens, but no further obligations apply in this process.”

The Earth has fallen.

Every corner of the world has been shattered into pieces, washed away by the blood and tears of the people, embarking on a journey to a distant place.

But humans are social creatures. Scientists did not give up in this situation and finally succeeded in negotiating with the government. The method they chose was something seen only in science fiction novels. Going into space.

About 50 large spacecraft are prepared, and the people on each ship begin a long journey with hope for the future of humanity.

Their goal is to enter the orbits of the moons of Jupiter, Saturn, Uranus, and Neptune and attempt a form of symbiosis.

However, such a great challenge always faces obstacles.

Signals from several ships were cut off or turned back toward Earth. The control tower went into emergency mode.

The passengers must ensure the ship reaches its proper orbit, transfer data from the human world, and perform tasks to establish the foundation for a teleportation function that breaks down essentials into atoms and rearranges them at the destination.

All to eject the anomalies (hereinafter referred to as "Impostors") who received training and hid on the ship while pretending to be our comrades.

The Sekai has successfully approached Jupiter's orbit. Now is the time to perform your duties.

Always watch your back.

You never know when you might be run through.
