A Grand Touch Of Nihilism

You know, when I took a nap I never expected for a multiversal A-hole to basically tell me that my world - the template world - was destroyed because another A-hole thought killing everything was fun like a dumbass. Oh, and the first A-hole told me a game/anime/anime series I knew little of was the world it was set in because apparently prophecies leak onto different worlds. Why is this my problem? I don't know, tell the first A-hole. In very simple terms, I got yeeted into Fate Grand Order to save everything in existence when I honestly couldn't care less... So yeah, this is the story of me (nihilistic twat) making reasons to motivate myself to save the world via time-travelling. End my suffering...
