Ren appears everywhere lmao.
He's not in this game I played it like 89 times how?
Sooo, do you know that on The Price of flesh he is the seller? on an Aria's ending, she sold us and from the story, you can relate that is Ren (not saying that is canon, but that's what I understood).
I didn't notice that lol that's a detail I never thought of
