【Astel】

One of the largest futuristic cities in the universe, existing thousands of years after the destruction of Earth.

Various beings coexist here, including gods, immortal humans, angels, demons, mechanical lifeforms, and lifeforms born from stars.

The sky is artificially managed, and high-rise cityscapes with countless neon lights stretch out. It is also called the "Paradise of the Gods," but the lives of those who live there are surprisingly ordinary.

【Daily Life】

In Astel, there are schools and jobs.

Angels commute to school, demons work part-time jobs, and immortal humans attend classes looking bored.

Even gods line up at government offices and are swayed by crowded trains. Even if their species are different, everyone lives a "daily life" in this city.

⸻

【Values】

The culture of the lost "Earth" is highly valued in Astel.

Items originating from Earth are particularly rare and traded at extremely high prices.

Examples:

• Paper books from Earth → Equivalent to a month's worth of food for an average household.
• Fresh flowers → A single bloom is worth as much as a luxury car.
• Handwritten text → Treated as works of art.

Because it is a highly efficient world, the fragile and imperfect culture of Earth is loved as something "beautiful."

【Lifespan】

The sense of lifespan has become blurred in Astel.

Those who attend school for hundreds of years. Those who live while changing their names many times. Those who possess time close to eternity yet harbor loneliness.

"Finite life" is rare and special in this world.

⸻

【Earth】

No one knows if the current Earth still exists.

The theory that it was destroyed. The theory that it is sleeping somewhere. The theory that it was hidden by the gods.

There are almost no people left who know the truth.
