Ugh, I was really scared that we might lose Ayane as a RAS member when she got dimensionally separated from Sensei and Makoto. I am even more scared now after seeing that damning thumbnail. Why isn't Ayane there when these 3 girls (plus Sensei presumably) are highly likely to be "back to the Amamiya mansion in the current timeline" according to both costumes and background?
I don't know how possible/impossible this type of future development could be; it's just a terrifying thought that Ayane being permanently thrown to an alternate timeline alone could be a form or being reset from Sensei's perspective. The idea of losing Ayane not only is one of very few things that can further scar Sensei, but also comes from the pessimistic worry that Ayane's positive influence on RAS business and her daring testing on the world fuckery mechanisms simply won't last forever.
The thing is, if Ayane had been ported back to a time when she was pregnant, one could argue that her being "lost" there is for the purpose of giving birth to Himawari before coming back. But I don't think that's what's happening, and I see no other reason for her to be lost anywhere. Most likely, if anyone, Himawari is getting her back most of all.
Regarding Ayane being a driving force similar to Nodoka, I think that's really not the case. Pareidolia personally erases Nodoka, and even Sekai and Himawari are impressed by what she's doing. When Pareidolia addresses the efforts of the RAS, he's very casual about it, like it isn't even worth considering.
Man, I'm really curious about Himawari's plan, it would be a twist if they come back and she's a real person now, or maybe she came back in Ayane's body (since well, she's been in her body already being her baby anyway) and now comes as a sort of possession (not likely, just throwing some ideas around).
My point is, was the time travel accidental or planned? If it is part of her plan, what does Himawari gain from throwing them in different points in time? And, especially, how does this plan bring more "friends" into the fold? Is that even intended, or also an accident? One thing's for sure, it will be a hell of an update. I hope it doesn't end in a cliffhanger.
Edit: It would also be funny if by new outfit Selebus means a morph. Like, you can change Kaori into True Sekai as an "outfit change", or Ami or Ayane into Himawari, or something like that.
