And i think that was just a snarky remark.
As i said, i think she thought of her as an alibi relationship.
We know that Akira never laid hand on Nikki, before recently (there are some implications with that depending if Sekai is up to date with things happening).
And i think Sekai knew Akira didn't have a physical relationship with Nikki, when she was alive.
And i'm with you and others, that Nikki might have been Akira's save haven from Sekai, or at least, a different approach for a relationship.
An interesting thing is:
Nikki tries to resolve Akira's problems by offering him to listen and take things out on her mentally.
Nodoka's attempt to resolve Akira's problems is to offer her body to his physical desires.
You think she hates Maya because she made him cut all ties to her and the... Nakayamas? (Nikki's family, forgot the last name.)
IIRC. Please don't nail me to it.
Sekai giving away why she hates Maya might be an important plot point we're just not allowed (by Sel) to have yet.
Hate needs a reason. And the reason i see in conjunction with the story so far, given the sexual abuse, predatory behavior and what not, one of the games tones, is, that Sekai saw Maya as a threat.
Akira picked Maya up and took her in, and he had the same predatory/faulty relationship with her, that Sekai had with him.
Only this time HE was in control. Sekai might had foreseen a shift in power relations. No toy Akira anymore.
I think that'd be a big point, to be jealous of Maya and therefore hate her.
If you wanted to point out that Maya was taking Akira away from Sekai, at least here, we're on the same page.
Or, if that really is Sekai, she's just ranting in bad mood.
*How dare you fucked that disgusting bitches pussy and* blah blah blah yeah it's ok Sekai, you don't like her, we got it. How dare Akira fucked someone besides you, you Nozomu fucking hypocrite.
Maya and Akira being fucked up was due to their pasts. With Maya's past still being a mystery and Akira's past being due to his upbringing and Sekai and the car crash. (While still, we don't know about Sekai's true nature. Meaning, if and what she is, if she is.)
If you're getting at the times where Maya fucked up some Akira incarnations in the cycles, we'd need to know if Sekai knows about it.
I think the reason Maya presumably forced Akira to cut ties with the Nakayamas and his past, was that she knew that his past would make him suffer. Did she wanted him all for herself? Yeah seems reasonable. The sole purpose? I don't think so.
But we know this, from Baby Finches (depending what the event really is):
No matter what "A" Sekai might have thought or "thinks nowadays", Akira seems to have been good, with Maya alone.
(BF is pretty messy so i rather leave that in limbo.)
The problems i see here at most is that:
We still miss important info. Thats to be expected.
For me, we still need to know:
Was Sekai ever real? (Is anything in the story real? PERCEPTION)
If she was and died, was she really coming back, at least at the Yasu event?
Or is she just Akira's memories incarnate?, his perception. Like everytime someone comes up with Sekai related topics, he imagines her, and because he doesn't want to remember, he glitches.
It's hard to make any assumptions about Sekai if we don't know if her knowledge is restricted to pre car crash, or because of her living on/resurrection, knowing things that happen now.
