Stationed all alone in a vast space observation dome 20 light-years from Earth, a man continues to fulfill his duties, completely unaware that his base has been abandoned and HQ has cut off all contact.

The observation base is equipped with a duplicator capable of creating almost anything, so life support is not an issue. However, prolonged isolation and boredom are slowly eating away at him.

He had spent days sending out hundreds of emergency signals, never knowing if they would ever reach anyone, until one day, a message accidentally got through to Guest.
