my atsuhiro hcs:
he was one of the first proper/long term league recruits (under tomura's leadership anyway) and works alongside tomura to help strategize their missions
he has a bad knee from an injury that healed wrong, hence his cane. he definitely plays it off well, but it hurts some days more than others. i think some people assume the cane is just for dramatic flair, but he absolutely uses it
he has arthritis as well, and generally can't afford the pain medication he'd like to use, even with giran's help. i kind of like the idea of him being more disabled in a society that clearly favors showering money upon heroes while other people struggle; it adds depth to him
despite these issues, atsuhiro will put most everyone else first. he usually ends up cooking for the league to try and save money and he keeps track of what everyone prefers to eat. still, he can be pissy about this, as seen by him complaining about food and other things they can't afford. he can be very overdramatic, but underneath that he is really worried about the well-being of the league
like many people in mha seem to have, i think he has increased endurance, but i also think he has increased agility, given his ability to jump/glide such far distances, like seriously it's on par with characters like endeavor, deku, bakugou, etc who use their quirks to do that, especially when he can launch himself IN a marble up into the air too?
his eyes are a more goldish brown, that being my personal preference, but also i just like this art as reference:
