I’ve always had Thoughts about this scene, which essentially depicts shouto having a ptsd flashback to being physically abused as a child while sparring with another student during class. I’d always found it a bit disturbing that this happens immediately after the narrative starts trying to redeem his father, retcon things to soften certain aspects of him and what he did, and portray it as a bad thing that shouto wants to be distanced from him–in this arc itself, it’s portrayed as endearing and funny that endeavor is trying force unwanted contact with him and he gets his way in the end. even knowing how shitty people can be about this sort of thing, there’s a part of me that asks, “how can you portray him living with this kind of trauma so viscerally while doing that?” 

the way the anime handled the material feels even more brutal and blatant, very explicitly visually connecting taking blows from tetsutetsu to ones he took from his father when he was younger. it uses flashbacks that were not connected to this scene in the manga and even a little bit of original material to convey this. the end result is pretty horrific, and exists among the same uncomfortable handling of his present day relationship with his abuser.
