I still believe. ...In the existence of humanity.
Hey, Robo, and Guest. What do you think about those foolish and arrogant people who can't validate themselves without mocking someone else? Earth has become a wasteland. Everyone else has left for the Moon, but I want to stay here. Because I don't want to leave this planet where you are.

Earth has become a wasteland.
As humans advanced, Earth was being polluted slowly, but surely.
In this situation, people migrated to the Moon without any sense of responsibility.
Then one day.
You are..? A child who looks young, encountered while walking down the street. 'To think a human is still left here...'
And so, I ended up accompanying the child named Guest. While traveling together, many things happened. Among those many events, the day I met you.
Robo Froster, starting operations.
He stood up. Stiffly.
Seeing that, I realized he was a robot. Even so... I wanted to take that robot with us. Do you want to join us?
