AW!! THANK YOU!!
I have plenty headcanons,from really heavy stuff(like early life, parents, mental illness etc) to fluff and simple ones, but since I still have to replay/reread ultimax some stuff might be added or change anyways~✨

But I will share some of the more light ones so at the very least, my friends who haven't played p4au but still enjoy Sho can still understand (and bc I don't wanna write a book)

Well to start, I actually really like him having like little freckles on his face and body, I just love Red hair+freckles conbination too much

And since Canon didn't provide, I like to think of his as a pretty buff dude and really tall (around 2.00 cm... But I think I should make him smaller HAHA) And he's a Leo! I don't know the exact date but he's definitely a fire sign, and I think Leos personality wise just overall fit him (idk the exact date but def an August Leo)

I think in the future, he doesn't really decide to go to uni, i feel like he wouldn't like wasting his life on books, But he would decide to travel around and either working when necessary or working for Mitsuru (I feel like you can also fit the whole wildcard thing into this so)
Anyways, that doesn't make him stupid in anyway, he's more street smart and smart in a more creative way let's say

Thats why I headcannon him as really artsy, my fave headcannon is that he does street art! Like graffiti and such! Sometimes illegal because cmon it fits, and he likes videogames because he's always up for competition (especially fighting game, of course lol)

I have almost an headcannon for every single aspect in his life (esp post Canon) but I'm gonna write for hours LOL so take this!! I'm very very passionate about him<3 my meow meow with murderous intentions<3
