As I haven't reached this part in the game yet, I still have to say that some parts of it seem disjointed, like how Misuzu finds the pair afterwards, which hopefully they'll explain in coming episodes. At least they keep the 'Red Night comes suddenly' feel, I like seeing that glass breaking effect.
Stuff I'm theorizing about or just pointing out:
Spoiler:
1. After all that KakeruxYuka buildup earlier, it's like he's taking care of her as a casual friend. Kind of contradicts his desire to be strong to protect her. So far in my game, every time they run in RN, he's holding her hand. Possible strong indication that Yuka route is unlikely.
2. In mirroring, the holding off on Kukuri's proper intro seems to show that she'll be tied strongly to a scene climax and therefore a good contender for ending heroine.
3. Addressing of Lizette as a witch, who has been sealed for a long time before the start of RN, coupled with the mention of Kusakabe Misao, about 70 years ago, adds to my theory that Black Knights might be withholding something BAD by sealing Lizette, as well as the identity of the person in the ending, whose name we now find out.
4. Fall of Gura was like way too easy, so its likely to focus more on heroines, like I mentioned earlier. Someone will probably expand on this.
5. So far Kakeru's eye is OBVIOUSLY related to RN, extremely much so.
6. Fun indication: Shiori's Index book title runs from left to right, but the binding is opposite of that?
Game differences that I just point out for the fun of it:
