Wow, this is pretty fun, but also exorcist girl has the worst case of Anime I've seen in a while.
Like, she's suspicious that she doesn't know what's going on because she was told she doesn't know what's going on and her boss also reminded her that she's admitted that to others in the past! And yet rather than Just Fucking Talking (the number one method of getting other people to give you information) she jumps straight to violence at every opportunity
I get that she feels betrayed and enraged, but I think the "I don't believe Obsidian has amnesia" bit took far too long to resolve narratively.
