Ushiromiya Maria from Umineko No Naku Koro Ni*
- can't spot lies, always takes jokes/irony/metaphors etc. seriously. ALL of them.
- not exactly an aspie trait, but she is really childish for her age (she's 9). you can say it's a general anime character trait, but she keeps getting scolded for it, and she doesn't seem to have a clue what she's doing wrong.
- acts generally awkward IMO.
- very intelligent.
- is an occult nerd. she's basically a living encyclopedia about magic. (also, the creators Did Do The Research, so she's not making the stuff up.) because of that, she keeps getting asked to explain things and provide info (by adults), and is treated seriously (or rather, her knowledge is). a f****n 9 year old.
- in general, the best way to handle her is to ask her about her interests. she keeps talking about it and looks very happy when she does. XD and it may be just me (or the translation), but she sounds suprisingly mature when she explains things.
- despite her epic memory, she has bad grades, since she can't learn things that are uninteresting for her. so yeah.
- despite beeing friendly and relatively outgoing has no friends. AT ALL. (and it may be just me, but i think she's a really cute kid, and i just don't get it, how one can not like her, even if her interests are creepy. >.> unless you assume her social skills suck, that is.)
- gets bullied at school for beeing creepy.
the problem is, since it's a sound novel, we don't know anything about her bodylanguage, nothing about her eye contact or anything. and anime adaptation isn't the best source of information, so yeah. (and LOL, most of her facial expressions aren't even physically possible XD we get creepy higurashi faces again.) she may act suprisingly normal, depending how you imagine her.
she may not be aspergers, but she's deffinitely weird, with some autistic traits. and she reminds me of me when i was her age, like, A LOT. except i wasn't into occult. XD
*it applies more to the novel than anime, so yeah. you may disagree if you're anime only.
