1Q84 - probably the most autistic book I've read (definitely more autistic than No Longer Human)

I love how Aomame - who was raised in a Apocalyptic christianity cult, tries to scientifically test her reality and has a hard time accepting she's been isekai-ed. But Tengo - an athiest math prodigy just is like "huh I guess things are magical now".
tengo is very nearly a based neet, but not because he is antisocial, just because he likes being in his house.
aomame is forced into neetdom and flourishes in it.

Ushikawa is definitely a failed normie who embraced his autisim.

then of course there's Eriko.

anyway. it's great.
