[Shoto continues to look confused until the following information before he realizes that there's an honorific and a definite school issue. He had certainly never gone to a school as a child. Ever. Like maybe in a car in passing because he had to go somewhere his father wanted and that's as close to a school and not private tutors that he ever got. He opens his mouth to make the correction and then his scar is being pointed out, so he shuts it again and waits. He doesn't mind, not only does this guy sound agitated about whoever he thinks he is, but the transition from literally your life to here can be jarring.

Okay, definitely not the same person.]

My explanation is that my name is Todoroki Shoto, that my scar is real, I've had it since I was very young and was born with my hair this way.

[The tiny bird pokemon on his back doesn't like the sounds of this kind of conversation and Shoto takes her into his arms instead to tell her that it's fine.]

I'm sorry, but I think I'm not the person you think I am.

[With a very glare-glancing bird, Shoto tucks her into his chest to hold her with one arm while he takes out his trainer card to prove that his name is as it is, picture is as it is and the pertinent information.]

Here, please.
