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 always have... and I always will!
!لطالما فعلت... وسأبقى أفعل
Das habe ich immer
und werde ich immer!
Siempre lo he hecho…
y siempre lo haré.
Siempre lo he hecho…
y siempre lo haré.
Ça a toujours été ainsi,
et ça le restera.
Come ho sempre fatto... 
e come continuerò a fare!
Fui assim até aqui,
e serei assim daqui pra frente!
Так было всегда... и будет впредь.
