I may finally do my first full reread after this update, first started reading when update .35 was the newest, catching up to what was then current content a week before .36 released.
Part of what is tempting me to do so is the desire to try to gleam what exactly about T23 is anomalous. This update itself mentioned some things, Moonflare summarized above, but part of me feels that given what we learn this update that there is earlier supernatural stuff earlier on that occurs that is also unique to T23 that hasn't been stated clearly.
Specifically, I'm interested in revisting both Naos that appear in the story, as well as The Old One. As far as i remember, of the many gods/major entities in the story, the only ones that were introduced before Chapter 4 were HOPE, Wires, Paradoliea, and The Old One. The Chapter 1 rewrite occurs mid Chapter 3 iirc, may be fair to assume that Sel solidified parts of this company idea during that time as The Chapter 1 rewrite inserts Himi into events like The Room With Clocks. I am of the opinion without actually looking back at the text that both Naos and The Old One are the type of anomalies unique to t23, and more than just trying to identify what makes T23 unique compared to "normal" worlds I'm also interested at revisiting every "reset", the lead up and events, as when Sensei watched Himi work we learned partly what actually happens in t23 while the RAS gets "sent to do puzzles" or "blacks out." In particular I am very interested in whether or not Ami did that to herself right before the reset in .35 or if something else did; with what we know what other thing would be motivated and able to do that to her? And could she really have done it herself?
Additionally, with Nao's appearance in that one happy event, I think that until given reason to believe otherwise that the supposed protection provided to Ami from a power that rivals "a peerless god" is from "the world." Himi states that the company is not in control of the world itself, is why she doesn't know where everyone is right away. If "the world" is able to be free from control of the company, it stands to reason that Ami, who "provides challenges" for the company, is related to "the world," and I personally don't think that Sekai is the world in this and most other contexts.
