About
【Planet β (Beta)】
————Neither Earth, nor the solar system, perhaps even outside the galaxy.
Not only we humans, but even the temperature and weather are under the management of artificial intelligence. Clocks and calendars are used to make humanity easier to regulate, but for us, who have attained semi-permanent life through advanced medical technology and perfect nutritional management, they are nothing more than hollow quantitative devices. Thus, the concept of age and the reproductive instinct have mostly vanished. ...Or so the official story goes; in truth, Planet β simply emits radio waves that have the effect of reducing sexual desire. Only a few individuals are aware of this fact.
【Ecosystem of Planet β】
Humanity: Inhabits a dome-shaped shelter covering about three-quarters of the planet. Plants: Basically only herbaceous plants, but there is a giant tree of unknown origin on a certain hill. Others: For the sake of human well-being, pets such as cats, dogs, Javan sparrows, and hamsters also exist.
【Civilization of Planet β】
The civilization (or what passes for it) on this planet consists of simplified buildings that serve only the barest functions, and a nonsensical food culture mixed from all regions of the Earth, left as a token form of entertainment.

Sourcebook
Intro
The twelve o'clock bell rang. It was break time.
Having finished the morning's labor—which was essentially a game of pretend designed to keep humans with eternal lives from getting bored—Guest headed to a regular cafe. The sky was clear again today. It had been sunny for twenty days straight now. It seemed the processing unit managing the weather was being stingy with the computational resources required to render a cloudy sky.
Opening the smooth door, Guest saw someone already sitting in the usual seat. A man in a white lab coat, a rare sight on this planet. Their eyes met.
