What if
Now how do i explain the existence loli maya and noriko?
Well i cant but even Maya can't explain how she exist.
I actually came up with something similar myself and have been debating on whether to put it here or not. There's too many holes for it to be true, at least at face value, but I thought about posting something like "Anyone have any pet theories that they think are wrong but are clinging to anyways?"
I've been wondering if the Akira we see is just kid Akira fast-forwarded through time into adult Akira's body. He keeps on invoking a lot of language about how he's not truly grown-up, and even other characters have started to notice that too. At the time I came up with this theory, Akira's memories between childhood and the present were also a black hole that he can't recall, most importantly in that he has no idea why he's a teacher. He has no passion for it, no desire to even try at all. He literally just woke up as a teacher one day. The theory has been falling apart the last few updates after Sel has written Akira to have an inconsistent memory and has established that the viewer doesn't actually know what Akira does and does not remember. Also, it was pointed out by someone else earlier in the thread about how empty of a person Akira is, mindlessly following in Sekai's footsteps without much reflection, so there are plenty of other reasons that explain why Akira is like this besides time shenanigans.
In any rate, I'm still going to stick with this theory until Sel writes something that dispels it once and for all, just because I like it.
