A neurodivergent is someone whose brain is different from the typical or “normal” person’s. It includes people with adhd, autism, Down syndrome, Dyslexia, dyscalculia, etc.
I would put Miko (definitely has adhd) in that spot and also Raf (this is less obvious but I believe the kid to be autistic)
I myself am a neurodivergent as I have both adhd and autism.
