absolutely! This AU is very self indulgent to me so it’s Shigadabi centered so we gotta have them both he alive, it’s meant to be a slice of life so lot of comedy. Some of my main headcanons are Uncle All Might, he is trying sooo hard to bond with Tomura in this AU and ends up very cringy because he tries to get into video games 😭, Also i imagine him having braided hair most of the time as Himiko braids it for him. I have to say in a more serious note he suffers a big identity crisis over his trauma with AFO and how much of him is truly him and not just AFOs influence so he experiments with lots and lots of hobbies and activities trying to find one that sticks. That ends up being expectedly gaming (mostly relaxing games now, he will never admit to installing dating games in an attempt to understand how normal couples act to try and do the same with Dabi) (this goes with my own headcanon that Dabi likes shoujo manga) but also lots of reading, he probably has whole bookshelves in his room filled with random stuff, from textbooks to novels. I have a lot more but i feel like i ranted enough.. i’ll see if i can write them all down one day and make a huge thread!
