'Kay that's nice and all. But what made me hesitate on it was that narrator in S.E.K.A.I said that the girl declined the offer and went on her way while Maya probably accepted it. It makes me wonder if the narrator lied intentionally and reason for that.
Also do you mind citing where Maya does seem familiar with Net Cafes? I know Maya collects masks in her dorm.
And on what happened in hallway. Well then it's plausible that Akira knew Ami died in subconscious yes. Though the one Ami talked to in Rain King seems to be sentinent and was able to communciate normally. Still I'm desperate to connect it with bared Maya standing at the end of school hallway for some reason. Do you have any idea?
About what murdered Ami, no idea. My initial guess was Sekai since Ami didn't seem like the type who would follow a stranger. And I think what Parrot screamed missing was Sekai instead of Ami, and sacrifice on a surface level was parrot itself. Or if we consider each god yearns for a sacrifice, Ami was the sacrifice for Sekai (Pareidolia)? Or was it Maya? Doesn't matter they both died in this reset. I'm so dead set on Ami being Maya that I'd consider Maya being molested by a relative a roundabout way for Akira to condemn himself.
I feel like Maya Prime mentioned Internet Cafes at various points, but the only time that's coming to mind is when she suggested that Noriko sleep in one:
It seems inconsequential, but this being her first real suggestion when Noriko implies she doesn't know where she's going to sleep, feels like it says a lot about Maya. Especially since she's in a frustrated state of mind, and just wants her gone asap.
Also, there was actually 3 deaths in that Reset. Maya's, Ami's, and someone from the Halloween party:
I'm unsure of why, but assuming there's a reason for 3 deaths, it could be related to there being 3 gods, moons, and at the time, members of the RAS.
Getting to the rooftop, and the requirements to do so, still aren't all that explained.

Unfortunately, I can't really say much about the Maya at the end of the school hallway, like in the Chapter 1 'Tick Tock Tick Tock Tick Tock' Happy Event. It does seem related to the Wishing Well, though, and possibly to Maya barricading the school hallways with boxes. It's a mystery.
Still, the Ami in Chapter 3's 'Rain King' Happy Event, referring to that school hallway instead of what had recently happened in the karaoke hallway, seems unlikely.
