I wonder if anyone in the discord will bring this up. If they do will Sel address it or just ban them? Maybe we're all missing something. What ever happened to Deskel BTW? I feel like he would have the best chance of explaining this.
The explanation is that Selebus added a line about Noriko that shouldn't have been there. The scene is about Niki and Akira getting interrupted by her mom. There should be no Noriko mention, but he chose to add it anyway and that was a mistake, because Noriko was a toddler.
I don't care if Noriko is 2, 3 or 4. It just makes absolutely no sense for a 4 year old to try to constantly sneak in on her sister and her boyfriend. And she's obviously not 4 if Ami hasn't been born. More likely she's at most 2, and how does a 2 year old sneak in anywhere? She would have been with her mom.
My take is that Selebus went from "Noriko always tried to hang around Akira when he visited their home", and yes, that tracks. But do you want to get into even more of a mistake? During the first flashback we get, which is supposed to be about Niki and Akira's first kiss, Noriko is also mentioned as trying to hang around him.
In spotless mind, Niki and Akira are even younger, haven't kissed yet, and yet Noriko is "some kid", not a toddler, not an infant, a kid. That would make her 4-5 years older than Ami at least. in fact, if she's already a kid when both of them were kids, when they get to Kyoto, she'd be even older.
So I can see two ways to explain this: Selebus is a big dumb dumb regarding Noriko's age. Or they don't actually exist. Now, calm down, it has been theorized that they really don't exist:
At the same way, the fact that Noriko wasn't one of the original characters to LiL (to my knowledge), could have messed things up slightly that Selebus just got his timeline wrong. I don't know. And since I have nowhere to put this, have this too:
Do these seem like real people to you? (last one might just be nothing tbh). Anyway, other than the last one, these are the facts as we have them now.
