Even I didn't see the twist about the owner of the Cinema box coming. What is great about it is it all made sense, and did not feel like a retcon at all.

I understand your dislike for Maria, especially with how she treats someone who cares so much for her. I am also irritated at how she can call Daiya her comrade and even admires him, while she treats Kazu, who has done far less brutal and inhumane things (IMO he has hardly done anything worth judging him for) like trash. Still, I can forgive her for it because I know it is only happening because of her wish and sin that automatically makes Kazu the enemy for trying to save her.

Is Maria's memory loss permanent? If so, does this mean that this is already the Zeroth Maria? Or is the real Zeroth Maria the one who was not stained by her sin and has not yet received flawed bliss?
