(3.8 rant)
What the hell MC even is at this point? My current guesses are they're either a Finality Emanator, one of Terminus' black cats or Terminus THEMSELF.
Things that hooked me to them are the line "I can change destiny and make up for what's missing", the fact that it was Kafka and MC who first found Firefly, Constance showing us Terminus' kitty and the last cutscene. From what we've seen so far, the only ones that are connected to time shenanigans are Pure Children of Anãsrava(Cyrene returning to the past to become PhiLia093), Nous(constantly calculating the future) and some of their blessings(Divination Matrix), Terminus(living backwards) and Elio(well, we know what he can do).
The first one is off the table immediately, we don't have pink hair. Second one is also out with the amount of dumb things MC says and does. We know from this patch's story that Terminus split THEMSELF into countless black cats that traverse backwards in time and they, like us, have amber yellow eyes, so it could be a possibility. We don't know anything about Finality Emanators if there are any, so the possibilities of what they can do are endless. I'd like to think MC isn't Elio since Silver Wolf mentioned that Elio himself refused to let Constance become a Stellaron Hunter, but who knows, maybe he's like Zandar
The lore drops from this patch are very interesting
(also, NO WAY THEY PUT THE OPPENHEIMER QUOTE IN THERE)
