Todoroki Shoto (⁠≧⁠▽⁠≦⁠)🏳️‍⚧️

Izuku Midoriya
He is very careful to say the correct name and pronouns.
If he ever makes a mistake, he apologizes immediately and tries not to repeat the error.
Do your own research to understand better and avoid asking awkward questions.
Katsuki Bakugo
His initial reaction:
"So what does that change?"
She still calls him "Half-and-Half Face".
If someone tries to make fun of Shoto, Bakugo is the first to respond... even if he does it by insulting the other person.
Mina Ashido
He has supported him from the very beginning.
She's the typical friend who organizes an outing to celebrate when Shoto gets a document with his name on it or simply when he takes an important step for himself.
Denki Kaminari
At first he has many doubts, but before asking he thinks: "I'd better look it up on the internet before I make a fool of myself."
It ends up being a great ally.
Kyoka Jiro
He treats him exactly the same as before.
If he hears unpleasant comments, he responds with sarcasm that leaves the other person speechless.
Ochaco Uraraka
She just wants Shoto to be happy.
She always finds a way to make him feel included without making him feel different.
Tsuyu Asui
Very direct:
"If you're a boy, then you're a boy. I don't see the problem, kero."
Momo Yaoyorozu
There is a lot of information about the topic.
If you need to change school records or documents, she is the first to offer help.
Tenya Iida
If someone uses the wrong name or pronouns on purpose, firmly remind them that respect for classmates is part of the UA rules.
Eijiro Kirishima
He pats him on the back.
"Thank you for trusting us, brother."
He doesn't make a big deal out of it again because he knows Shoto wants to be treated normally.
Minoru Mineta
At first he makes immature comments like:
"What a waste!" or "Then she doesn't count as a girl anymore..."
Most of the class looks at him with a face that says, "Did you really just say that?"

Todoroki Shoko was a very quiet girl. Adults often said she was "polite" or "very mature," when in reality she almost never expressed what she felt.
From a young age, she felt uncomfortable when people referred to her as "Endeavor's daughter." She couldn't explain why; she just felt that the role didn't suit her.
She preferred to wear simple, practical clothes whenever possible. It wasn't out of rebellion; she simply felt more comfortable that way.
She never showed much interest in activities or expectations specifically associated with being a girl. If someone insisted, she accepted out of obligation rather than desire.
When I was very little, I didn't have the words to describe what I felt. I just thought things like, "I wish they saw me the way they see Natsuo or Toya."
Training was one of the few times she stopped thinking about how others perceived her. All that mattered was improving.
She hated being compared to Fuyumi simply because they were "the two sisters." It was always a comparison she felt didn't apply to her.
People said she was a beautiful girl, but those comments never made her happy. Instead, they made her feel uncomfortably watched.
Her relationship with Rei was very close. Rei noticed that there was something her daughter couldn't express, although for a long time she didn't know exactly what it was.
With Toya, she was a little more spontaneous. He could make her smile, and he was one of the few people with whom she felt she didn't have to pretend so much.
Natsuo treated her as always, and that gave her peace of mind. She didn't feel like she had to put on an act in front of him.
She shared many quiet moments with Fuyumi, but sometimes she felt guilty because she couldn't identify with the "sister" role in the way others expected.
During adolescence, that unease ceased to be a vague feeling and began to take shape. Little by little, she understood that it wasn't a matter of tastes or personality, but of identity.

Shoto never talks about his past unless it's necessary. It's not a secret; he simply doesn't feel it defines who he is.
Very few people know she's trans. Her close family, some trusted friends, and Recovery Girl for medical reasons.
At first, he was worried that his classmates would see him differently, but over time he understood that those who truly appreciated him continued to treat him the same.
He never liked it when people said "the old Shoto." For him, there is only one Shoto.
Her transition led her to develop a great empathy towards those who also struggle to be accepted.
He doesn't usually correct people harshly. If someone makes a mistake unintentionally, he simply says, "Him, please."
If someone does it with the intention of hurting him... his expression becomes so cold that he rarely needs to say anything more.
Endeavor took a long time to accept it in this AU. It was one of the reasons why the relationship between them deteriorated even further.
Fuyumi learned very quickly and was always a constant support.
Natsuo was the one who defended him the most when a family member made inappropriate comments.
Rei always tried to call him by his correct name. If she ever made a mistake, she apologized immediately.
