1. Not confirmed as such, just loose theories.
2. It is not known why Maya but well she has a complicated past with Sensei and the world, plus the beginning of the game is Akira committing suicide in the famous Jump/Jump/Jump, a couple of other theories about it being kumon-mi some kind of purgatory or something else.
3. The reset is closely related to the Rooftop itself, and well there are a couple of theories that are not certified but what they had to do was be pregnant of Akira is still viable or perhaps lose the baby. It is possible that Maya once was too. or it could be some other deeper plan of the ''Gods''
4.It is very scattered in the game and you can find several things in this forum in the search engine, but nothing much beyond the fact that Sensei was Maya/Noriko's tutor, the accident that could have involved several, apart from being well typical of him Sekai's grooming towards Akira and how it is cyclical. The order of events in the past is quite theorized if you do a little searching.
5. Yasu is related to Hope, she is possibly a channeler of him, being Callous, the one who is strong in summer. Tsuneyo is related to Calm/Wires god with his father having some connection with him, and then kaori related in some way to Sekai spiders and pareidollia. and to that you could add Yumi a special existence in this world.
6. Calm Callous Concerned, I don't think I'll delve deeper into the topic but you can search for Deskel's posts regarding that and each one will be better explained. because it is long. to synthesize.
7. Himawari, also known as Daisy, or shapeshifter, almost confirmed daughter of Ayane with Akira.
8. Wall/Barrier; How can it be, just like the space war, it does have a lot to do with the Gods and their area of influence and also in some special events and happy events like when Nodoka's manic phase passes and this Himawari/Shapeshifter comes out of there. Nothing so illuminating yet on that topic.
9. Many things, especially because that is where the first event happens where Sensei goes into blackout and they show us that he does not have control, + that possibly one or more Gods have more power there, also with the place where Sensei made his tutoring + the pact that Noriko and Maya had to be somewhere in the city. And possibly by searching here you can see more extensive things but nothing so confirmed as to why that place is like that.
Could it have been her pushing to the "jump"? thus beginning some kind of infinite cycle for her to suffer for "breaking" the God's toy? That's why she can't touch him, it's Hell designed to make her suffer i guess.2. It is not known why Maya but well she has a complicated past with Sensei and the world, plus the beginning of the game is Akira committing suicide in the famous Jump/Jump/Jump, a couple of other theories about it being kumon-mi some kind of purgatory or something else.
She also might be a little more cray cray than she let's on, considering how Noriko talks about her having had such a negative effect on him (again... the jump thing). I hope it's not totally true as I'm quite fond of her somehow.
Again, some kind of connection from where he started it all, by jumping? It's not as if it didn't happen in the game anyway with Makoto.3. The reset is closely related to the Rooftop itself, and well there are a couple of theories that are not certified but what they had to do was be pregnant of Akira is still viable or perhaps lose the baby.

Tsuneyo's father made me wonder for a bit, his connection to the Gods or at least his knowledge would explain why he was keeping her shielded from the outside world for so long, knowing how the game works. He probably let her go outside when she was old enough to understand the world a bit more and be able to defend herself (that's why she was taught martial arts?). And she didn't disappoint, as she's one of the few to grasp the true fucked up state/nature of Sensei.5. Yasu is related to Hope, she is possibly a channeler of him, being Callous, the one who is strong in summer. Tsuneyo is related to Calm/Wires god with his father having some connection with him, and then kaori related in some way to Sekai spiders and pareidollia. and to that you could add Yumi a special existence in this world.
As for Kaori, it does make sense, considering the spider recuring theme, the fact that she "blacked out" to kiss him and her eyes turning red for that event.
I'll have to check that out as it's probably one of the most confusing part, it's all said in weird and confusing allegories, not helped by the fact it's not always clear who the narrator is at all times.6. Calm Callous Concerned, I don't think I'll delve deeper into the topic but you can search for Deskel's posts regarding that and each one will be better explained. because it is long. to synthesize.
Ok I have no idea how this came to be as a theory, the only connection clear to me is the forest trip between the two of them, but that's it for me.7. Himawari, also known as Daisy, or shapeshifter, almost confirmed daughter of Ayane with Akira.
Could be that the gods manipulated reality to create a situation that's believable enough where there's almost no competition against Sensei and there's no way to escape. It's the perfect sandbox for them to play with, putting their "champion" in an enclosed space.8. Wall/Barrier; How can it be, just like the space war, it does have a lot to do with the Gods and their area of influence and also in some special events and happy events like when Nodoka's manic phase passes and this Himawari/Shapeshifter comes out of there. Nothing so illuminating yet on that topic.
The fact that the place is always described as decadent, dying out and in bad shape makes me wonder if it's related to Tsuneyo's father health. The fact that he's dying out could mean that he has no vital energy to keep his part of the sandbox alive, although that would mean that he's more than just someone who's aware of the gods.9. Many things, especially because that is where the first event happens where Sensei goes into blackout and they show us that he does not have control, + that possibly one or more Gods have more power there, also with the place where Sensei made his tutoring + the pact that Noriko and Maya had to be somewhere in the city.

Well, lot to think and I'm sure there's more to understand, but thanks for helping me put some thoughts in it!
