Back on my neurodivergent OM! bullshit
Still trying to figure out formatting lol! Forgive me if this looks like ass </3
Content warning: Some of Satan's sensory-seeking behaviours written here are self-destructive.
Alright gamers Satan and Levi are autistic
Also do I even need to say that Mammon has ADHD. Fucking look at him (affectionate)
Satan has “needs to wear socks at all times” sensory issues
Mammon has “cannot wear socks or I will explode” sensory issues
Levi and Satan infodumping back and forth!!
Satan canonically reads light novels so you KNOW he and Levi have hyperfixated on some of the same ones. If their hyperfixations overlap, they do not leave Satan’s room for days
There are exceptions, but Satan typically leans toward “sensory-seeking” while Levi is more “sensory-avoidant”
Satan picks at hangnails, eats super acidic/spicy foods until his mouth hurts, taps desks, and clicks pens
Levi cuts all the tags off his clothes, can’t STAND stuff on his hands, and will use loud music/games to drown out other sounds
Mammon, Levi and Satan can all understand each other’s trains of thought
For example, if Mammon’s mind jumps to something unrelated and he changes the subject, the other two will be like. Yeah no that makes sense. Proceed
Satan and Levi don’t mask as much around each other
Levi can’t help but smile when he sees Satan’s hands start to shake from excitement while talking about one of his novels
I said it in my last headcanon post (here) but Satan doesn’t stim that much because he doesn’t know it’s okay. Seeing Levi do it helps him get more comfortable and do it more often
They’re not afraid to be honest and end conversations. Stuff like “I wanna go play games now. Talk later?” “Yeah sure have fun”
Levi uses tone indicators.
Satan doesn’t, but will send additional messages to clarify if he feels it’s necessary
Like, “Neutral,” or “Sarcasm ^”
Mammon denies it but finds them very helpful. It’s okay king I don’t get social cues either
