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.
I fight only for the justice 
that I believe in.
أنا أقاتل للعدالة التي أؤمن بها فقط
Ich kämpfe nur für das,
woran ich glaube.
Lucho por la justicia en la que creo.
Lucho por la justicia en la que creo.
Je combattrai
pour la justice en laquelle je crois.
Io combatto solo per la giustizia in cui credo.
Eu luto apenas pela justiça
em que acredito.
Я сражаюсь только
за ту справедливость, в которую верю.
