Chizuru being outside the door surprised me, but it was also expected in a corny way. I guess professor must be just telling them all where his secret hotel room is so he gets fucked over for some reason.
But honestly how the hell does it make sense the one friend's family owed a ton of money and the other friend is a weird shinto-christian syncreticist fundie and none of them were aware of this before shit started going down? It feels like these would have been important details to know about your friends, stuff that would have come up beforehand.
Also almost all of them are dead, what's going to happen now? The cat fight to end all cat fights?
