Grandma to the rescue once again.
Also, I really like how grounded so many parts of this title are in realism, given it's literal monsters masquerading as humans.
I am curious as to what body Takahashi will take next. I would be very surprised if she just up and dies at the end and leaves Itou alone; that's one ending that just doesn't really gel with the everything we've seen thus far, especially with how much she's changed alongside the strange human girl who wanted to learn how to be normal from her.
And that's before getting to the obvious need for a happy yuri ending, of course.
Surprisingly, I'd be satisfied with Mr. N being left alive as Kotaki. They're now fully aware that Itou & Takahashi have ways to deal with them, even if they can hide and spread themselves out as a contingency plan. Obviously the remain a problem if they insist on being a pain in the Main Duo's side (I guess literally in Takahashi's case), but they're like everyone else in this story: simply wanting to exist and survive and find a modicum of meaning in their time on this planet. Sure, it'd be great if they weren't being cruel toward others in the process, but ...well, monsters gonna monster. If Kotaki can manage themselves and not cause a fuss, then I guess it's whatever, ultimately.
Looking forward to the finale and how it all shakes out. Thanks for doing what you do, and carrying this delightful series to the end.
