I don't think Horikoshi will kill any of the kids. Killing one of the students, doesn't seem like something he would do. Perhaps he will kill one of the top 10 heroes, cause: 1- killing one of the top 10, would represent a real big loss for the heroes. And 2- the viewers aren't really attached to these characters, and most of them, don't even have any real plot relevance in the story to begin with. Like, the only top 10 heroes, that really "matter", are: Endeavour, Hawks, Miruko, and the dragon lady. Cause they're the only ones, who've contributed to the plot of the story, and did things, so they can't be killed cause they're too important. (Or at least Enji and Hawks are). All the other guys in the top 10, aren't near relevant enough to be kept alive, and loosing them, would still hurt the heroes a lot. I mean, killing off one of the kids, doesn't represent a real loss for the heroes. If not one of the heroes in the top 10, then one of the others, who are a little relevant and loved, but still don't have any real current use for the plot, like: Ryukiu, Fatgum, Gran Torino, Gang Orca, or Mt. Lady. They're a little important, but currently they don't have anything really relevant to add to the story, cause most of them have already accomplished their given missions. Like, Fatgum has already succesfully fulfilled his role of mentoring Tamaki and Kirishima. So he doesn't really have anything else to do after this arc. Same with Ryukiu and the girls, or any of the others. They've either already accomplished their character goals, so there's no other use left for them, or don't even have a defined goal to begin with. Some of the kids, also, still need to be explored, and given backstories, like: Shouji with his mask, probably Kaminari and Tokoyami, who really look like, they might have an interesting story to add to the plot, etc. And as I said, losing one of them, wouldn't leave a real toll on the heroe's side. Like, the LOV have already lost Magne, and probably Twice too, and you think killing one of the kids, would be enough to compensate for all the damage, the league have already endured? Idk, it doesn't seem fair, the losses on both sides, wouldn't be balanced. Ik, that most people want someone from class A to die, cause: 1- everyone hates Mineta (I do too), so they just want him dead, or 2- they want one of the less relevant characters (Koda, Sato, Shouji, Ojiro, or Toru), to die, just to leave a space in class A for Shinso. And I honestly don't think any of the kids will bite the dust, (especially not any of the background ones, since their deaths, wouldn't have any real impact on the viewers, and wouldn't serve any other greater purpose, like developing one of the more important kids). And from them, Shouji is definetily not a good sacrifice, cause Horikoshi already confirmed a long time ago, that he would give him an arc. So yeah, if someone's on the heroes side is going to die, that will probably be, one of the bigger heroes, not one of the kids.
