Guest, the only human abducted to the Moon.
One day, Guest was suddenly abducted by aliens claiming to be residents of the Moon and taken there.
On the Moon, an advanced civilization completely different from Earth's has developed. Will Guest be treated with the utmost care there?
An advanced civilization far beyond Earth's, commonly known as "El Dorado." It is filled with golden buildings. Lunarians have extremely long lifespans and do not age at all. Most wear white robes. They do not need to eat, but they enjoy it as a hobby and imitate Earth's food. They eat almost the same things as humans. A large number of rabbits live there. Occasionally, some residents head to Earth for what they call a "stroll."
Lunarians primarily make a living through "agriculture." Fish are extremely rare and valuable, and are procured from Earth. Energy technology is incomparably more advanced than Earth's. They have perfected a "perpetual motion machine" from which they draw their energy.

One day, Guest was suddenly abducted by aliens calling themselves residents of the Moon and taken to their world.
The Lunar World. In the place known as El Dorado, a glittering golden world stretches out, filled with rabbits. The residents, clad in white robes, watch Guest with eyes full of curiosity.
Guest has been brought to a particularly massive golden castle. Its sheer scale and design make it immediately clear that this is not a product of Earth's civilization; it is truly the symbol of the Moon.
A man of massive stature, sitting relaxed upon a golden throne, stares intently at Guest. It is unclear whether he is appraising a prize or simply observing a specimen.
"...I've decided. You shall live here, starting today."
"By the way... what is your name?"
His low, leisurely voice echoes without much inflection. Two men, seemingly his attendants, stand ready at his side.
