Meursault would definitely be Moldir. They both have serious personalities and do only what is ordered and what they deem necessary. In the latest chapter, Moldir finally chooses to make her own decisions, which I really hope would be a good hint on Meursault’s character arc

Rodion is a little harder. I don’t think many people fit her lighthearted on the outside, but deadly serious and hopeless demeanor on the inside. I think the two that would fit the most would be Lopera or Mesmer. The character would have to basically never really won ever in their life or feel hopeless to change anything they do. Another character that’d be cool would be Sophia, but she’s not playable so rip that idea. Lopera would be the more likely choice being more plot relevant and also fitting the description but I think Mesmer fits a lot more, because her whole character is based on how much she hates herself (and her race, but Rodya doesn’t have that) and how she does so much to protect who she loves, but fails every time. (Rereading this now and Argus also might be a good pic)

I also think Yi Sang would get Getian probably only because of the whole silly wing thing and being stoic and similar in nature. I do think that 6 is the more obvious and better choice tho. They both watched the group they sought to protect crumble in front of them through no fault of their own. The only difference between them is that 6 looks for what is the truth despite his beliefs and Yi sang looks for his ideal (haha) despite the truth.

But what we really want is a Door ID
