I’m a bit more qualified to give u my list of headcannoned autistic characters. I could say all of them but specifically:
Ichika, Shiho, Minori, Haruka, Toya, Probably Akito tbh, All of Wansho, Kanade and Mafuyu.. Though there are arguments to be made for quite literally all of the cast these are just the ones i could give you like a decent list of reasonings for off the top of my head. Toya most of all of course but that’s just because i’m capable of yapping about him more than any other character. In terms of adhd i think if you gave Akito and An an adderal prescription they’d have surpassed rad weekend like last year but i’m not as knowledgeable on that end of things so that’s as much as i’ll say on that.
