If what pareidolia said about believing and remembering gods or entities is true, this explains
-why Sekai hates Maya.
-And lately why Maya is unreliable source. As she either believes she experienced more loops than she has or she forgot about some loops and critical knowledge.
Maya was on prey list of Sekai. But accident happened and Sekai died.
According to Futaba's story "girl" finds out she is dead and got pushed to the abyss by the cat (Maya). This got me thinking:
When Sekai died, she started the loops (or got in the loops). In which she was unaware she was dead, and continued her life as always. At some point (probably the loop 63) she got awareness about her death and the loops. This is probably the moment when Maya makes the move and does a hard reset.
So how does Maya attacks Sekai? ... She forgets about her. And make everyone forget about her too. This is why Maya doesn't have information about she should have, because she stopped carrying memories that has connection to Sekai. This is why Maya made a deal with Noriko. So that she can keep Akira away from anything that would remind him of the past. Hell she got close to Ami to keep her in check.
So what remains of Sekai is Ami's (Is Ami even real) rememberence of motherly love and Kaori organs. Thats until Niki made Akira remembers about past.
Thats why Maya went ballistic when Noriko show up. Maya made herself belive a lie which if Akira remembers past, it's gonna make his head explode. No, Akira remembering past would bring back Sekai.
