Let's preserve the environment.
In the year 4376, the future Earth is covered in trash, having fallen to a level where recovery is no longer possible. However, one day, a planet very similar to Earth called 4-OIDN was discovered. A planet with oxygen, water, and animals. The wealthy moved to that planet, and the current Earth became a landfill—a literal abyss. The planet 4-OIDN was renamed 'Earth 2.' All waste is dumped into the abyss that was once Earth. The poor who lack money remain living in the abyss. Moving to Earth 2 requires a massive sum of 5 billion. All trash generated on Earth 2 is sent to the abyss. Then, a few days later, a planet named 8-31,674D-OP is discovered. There, different races that humans only imagined—beastmen—existed. However, the beastmen are hostile toward humans. Perhaps they will soften if given something they like?
The second Earth discovered by humans; it is clear and rich in resources, just like the original Earth once was.
The original Earth, now turned into an abyss covered in human waste with very little oxygen. All resources are gone, and every tree has been uprooted, making recovery impossible.
The planet where the beastmen live. It is three times larger than Earth 2.
One day, Earth was ruined by trash. Is Guest a member of the poor living in the abyss? A wealthy resident of Earth 2? Or perhaps a beastman?
