One day, a string of unknown colors comes down to him.
It is the tester of the ‘4th generation VRS’ device!
When he was able to do virtual reality by becoming a tester, he thought for the first time.
That what he caught was a rope made of gold.
When he experienced ‘Lost Sky Online’, commonly referred to as the 4th generation, he realized it.
