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.
But... How do I put it? 
The realization hasn't set in.
لكن... كيف أصف الأمر؟
لم يتعمّق الإدراك بعد
Aber … Wie soll ich sagen …?
Irgendwie will es nicht einsickern.
Pero ¿cómo te explico?

Pero ¿cómo te lo explico?
Todo esto sigue sin parecer real.
Mais comment t’expliquer ?
Però... Come posso dire?
In cuor mio, sento che non è così.
Mas, como posso dizer?
Não é como eu me sinto.
Только, как бы сказать...
Это ничего не меняет.
