As her reward for completing the quest, Tokitate gets to ask the Game Master whether this alternate world is actually virtual or not... and the answer is that it's an alternate Earth that branched off of the original Earth's timeline. Upon hearing that it's an existing world, Yotsuya trembles with the realization that he killed real people. Once he returns to the real world and resumes his normal life, the Game Master appears before him in the form of a young girl and leads him to a meeting with the next new player.
On top of that, they tricked 
us and tried to kill us.
فوق ذلك، خدعونا وحاولوا قتلنا
Zudem wollten sie
uns austricksen und töten.
Además, nos engañaron
e intentaron matarnos.
Además, nos engañaron
e intentaron matarnos.
Et en plus de ça, ils ont essayé
de nous avoir en nous piégeant.
Come se ciò non bastasse...
Além disso, eles nos enganaram
e tentaram nos matar.
Более того, они обманули нас,
надеясь, что мы тоже умрём.
