Ah, I actually answered a similar question up above. I can copy and paste everything I wrote because it'a pretty long. I try to explain in detail:
Ah, that actually came to mind while I was reading and again while I was translating. Your comment disturbed me (in a good way! Sorry, I can't think of the right English word lol) I wanna try to see if I can find out why that is. I agree with that part about 20% (lol I don't do percentages well). I mean no disrespect of course ^_^ I still think it explains itself once you think about it deeper. I guess because, for starters, the reason why I even stick around this genre is a coping mechanism because I know how it feels to be molested and raped and sold around as a child up until adulthood (I dunno why, it just works for ME to help me cope) so I tend to understand what's going on at a level beyond what was probably even intended. With that, especially the first time if you are older, you can just go blank and completely not even think to fight. Later on I know they used drugs on him, but I'm not exactly sure what kind of drugs it was (I was thinking it was those "make you horny" drugs, but then also it could be something to do that AND weaken him at the same time). And then also, it's very subtly hinted towards - especially in the title - but he was feeling extremely ashamed about being raped like that, and his fear was of Midoriya finding out about it; he was even thinking to himself that all he had to do was say something while Midoriya was on the phone and he would've been able to get help, but mentally he couldn't handle Midoriya knowing. (I am half their race, but I grew up in America. Here in America we are pretty open about rape and things like that. Around my Japanese family and friends though, it's like a strong "don't say that, it's very shameful" kind of influence. That's changing though and there are a few advocates now, but I remember being little when my friends found out, especially one of my very close friends who was Japanese; I wanted to commit suicide to rid myself of the humiliation. (Luckily though I was able to endure this feeling, which is why I can talk about it so openly like this, but on Japanese sites I still get a little scared to do so for some reason, because of the influence of the culture.) So maybe that might not translate over well into Western culture, but - for this fanfiction - for Midoriya to know that Todoroki was being raped is similar to...hm, maybe the same amount of shame one would feel if everyone found out you were sexually attracted to children here in the West. Rape is not the victims' fault, but the exact same shameful feeling is there. If I push away my Westernized mindset and think about being around the other half of my family
At the beginning though, when they kidnapped him by hand, I figured maybe he would definitely try to light them on fire or freeze them almost immediately (Because, with him being abused one would think he'd freeze up as well right then but Endevour basically beat him all the time in the room until he started fighting back so it's ingrained in him to do so, in my own personal opinion though.), but I know that Dabi grabbed him by the face (and I remember Dabi telling him he'd lose his arms if he fought back, hinting to them having some plan already to counter him if he fought) so maybe that might have something to do with it? Maybe Todoroki sensed something and concluded that it would definitely not be a good idea to try and fight Dabi. But also Shigaraki was there and all HE would have to do is touch him and he'd be dead (well, when he touched Aizawa it was happening slowly so I dunno).
Sorry, I wrote too much. It's an occupational hazard, hehe. But I really love analyzing things like this. When I write (my original work is all in written form rather than graphic book form) I find what would get in the way of what I want to transpire and come up with an effective way to render it useless or unable to occur, so I am sure the mangaka (er, doujinka) had their reasons. Or maybe they didn't. But I still really love the story and am thankful to them. I am glad to see your comment, it made me use my brain, hehe.
Todoroki... why u no use quirk??! ┗( T﹏T )┛
