Well that was disappointing. It really gets to me when stories feature deceptive emotional manipulation, so now I'm hooked.
Now I want to know the back story of the real Ayaka Takahashi, who was apparently a real girl that she ate.
Also, thinking about whether it would make sense for Itou to end up being a monster too, in the end. I think it might, but I'd have to go back over the previous chapters again and check out her reactions to things.
