Fuck it, Haikyu!! characters and their unusual skills hcs
Ushijima is very good with distinguishing tastes. Like he can tell you if a drink is or isn't diet (combine this with diabetic tendou?? for the ultimately sweet (pun intended) moment of him telling the waitress that his boyfriends drink isn't diet and that he'd like another, please) also this makes him a very good candidate for developing chocolate recipes
Kuroo and Kenma learned some simple sign language to communicate without words (comes in handy when Kenma gets overwhelmed at a party, for example). Sometimes, they use it early in the mornings because neither of them are early birds and get grumpy without caffeine.
Kageyama has a very sensitive sense of smell. He will outright tell Hinata if he changed his shampoo because he can smell it (and because most of the time doesn't like it).
The Miya twins are actually really decent singers if you get some alcohol into them. They are also really good at whistling (it annoys the hell out of their partners sometimes).
Sakusa can mimic people really well (he's perceptive and picks up on their habits and speech patterns really quickly) and his impression of Atsumu has made for quite a few scenarios where their team cannot stop laughing because of how good it is.
Kita can sleep practically anywhere if he's exhausted, he just chooses not to for his own dignity (until he moves in with Aran anyways, who finds him asleep spread out on the floor multiple times).
Suna has a very dextrous tongue, i.e., he can tie a cherry stem in his mouth (do with that information what you want, honestly)
Hirugami can mimic certain animal sounds really well and sometimes does so almost out of reflex (maybe a verbal stim?) when he treats animals at his job (i.e. he'll "mreow" right back at a cat).
Akaashi can wiggle his ears and nose and does it sometimes when he's bored.
Bokuto can walk on his hands when he does a handstand (I mean, overall, I think that he could be very good at gymnastics)
