Not sure if it changed from the WN and LN but I wish they would’ve included the scene were Emilia doesn’t know anything about the Witch Cult. That scene also shows a bit from the old Crusch when she demands Ferris to apologize. Since they didn’t include that scene, they didn’t include the part...
I’m team Nino since the beginning but at this point Nino and Ichika are the obvious choices. I feel like it has to be either Yotsuba or Itsuki and for some reason I’m leaning more towards Itsuki being the bride.
