"Heroes can't save everyone" We already knew this! Repeating what we already knew isn't a satisfactory conclusion to anything.
If Ochako started off as naive girl who thought that everything will work out in the end, then coming to terms with the realities of heroism could have been a fitting ending. But that is not her story at all! Ochako's arc was kick started after carrying dying Nighteye in her arms. She is well aware that heroes can't save everyone. Because naivety wasn't her character flaw, the failure to save Toga doesn't develop her character in any way nor does it showcase her growth as a person. And it's not meaningful for the story to end with an answer to something that was never the question. Her character flaws were the sense of powerlessness and emotional suppression. Saving Toga in a confrontation of raw emotion would have broken her out of that suppression and helplessness and thus would have been a powerful culmination of her character.
Secondly, we already had "Heroes can't save everyone" when Hawks failed to reach out to Twice. The death of Twice made Toga question what Ochako wants to do to her. I thought that was set up for the cycle of violence to be broken by the new generation. Apparently not. Toga dying despite Ochako doing everything right, coupled with the fact that Tomura died and Dabi is dying too, makes it feel like heroes cannot save those who have fallen through the cracks, no matter what. Isn't that just awful?
Ochako's arc ends with the person she wanted to save dying in her arms. Again. The hero failed to save the villain. Again. On top of all that, the poor girl is suppressing her feelings. Again.
It's redundant and unsatisfying. Makes it feel like we didn't progress at all - just repeating the old failures.
Also I don't want to hear about gritty realism when this manga has this fucking thing lmao
In the same chapter where Ochako has a breakdown over Toga apparently dying from blood transfusion no less. Unhinged.
