Well, I do agree that if you play the entire game in one go and stay out of the "fandom loop", as you say, then yes, it can make for a much better game. I read a
lot of bad shit. And even with all that practice, if I had to wait month by month to read them, I just wouldn't be able to do it. When you can read it all in one go, even garbage can be dealt with. Not that LiL is that bad, but it's clearly better if you don't have to sit through update to update.
As for
Himawari's name being obvious...
Regarding the Ami situation,
I don't think they're working together, but that Himawari posing as Maya got a reaction when Ami came in exactly because they're not. It was just like when Tsubasa figured out she wasn't Touka, and obviously she couldn't have been Maya, because Maya was with Ami prior to getting killed and having her head gifted to Akira.
It might be relevant to remember that Ami's death triggered the end of the resets in "Times New Roman". Selebus said that it was the first canon ending to the game, and the world seems to be doing fine 10 years later (which can either help your theory or not, depending on how you look at it).
