What do you think we will learn about Nana? I'm excited to learn anything of previous One For All users and just what they were like, obviously never been at the same level of All Might in popular, but at least nana had enough enemies for them to come after her husband. Have a lot of them been quirkless users or All Might and Izuku being quirkless just a coincidence
To be honest, I’m not really sure about what exactly will come out for Nana Shimura. In the few flashbacks where she made an appearance, she told Toshinori he should be proud of his power because he won it; he was different, he was quirkless and earned his power.
She seemed to think Toshinori was a curious one after all and found his grand ideals interesting.
I’m curious about One for All overall, can it activate a malfunctioning plus alpha system? Does it means everyone has one and it could be activated somehow? From a storytelling perspective, I think that being born quirkless is a special trait Toshinori and Izuku share that brings them closer. If a lot of previous users of One for All were quirkless, maybe it would make it less special for Izuku and Toshinori’s relationship, and would make his story and achievements less groundbreaking.
Toshinori still keep a lot of things from Izuku; he’s more knowledgeable about One for All that he lets it know, but I think he would have say so to Izuku given how he admitted he was himself quirkless. One for All is a quirk that accumulates power, so All Might was probably more powerful than Nana, and Izuku will be even more powerful in the end. You’re right though, for enemies to come for Nana, and particularly All for One, she must have been powerful. But I think the most special about her was less her power than her convictions. All for One seems to heavily despise her for those.
If she was that powerful, she would have been a legend, like All Might, but Izuku seems to know nothing about her. So she didn’t quite make it into history, but she was enough inspiring for All Might and threatening for All for One for the both of them to be strongly shaken and forever remember her. It seems Toshinori will never be over her death, as he still strongly resents All for One for what he did. As for All for One, he despised Nana so much he came after her descendants. We still know nothing about Shigaraki Tomura backstory, apart that he was taken off the street by All for One.
I suppose that with a quirk like his, Shigaraki was harshly rejected by others. His quirk is destructive and deadly. Shinsou was already mistreated because his comrades at school were afraid he would control their mind. So a child who can kill just by touching you? Can you imagine how terrified he must have been by his own powers, and how he must have been thrown off? And, in fact, could we suppose All for One gave him this quirk without him knowing so he could ’rescue the child thrown off by hero society’ and manipulate him just because he was Nana’s grandchild? Even if it’s not the case, he still took care of Shigaraki and raised him so he could fight against hero society and particularly All Might himself.
For this hate to be ingrained like that, All for One must have truly despised Nana. He mocked All Might for his ideals about peace and hate him for disfiguring him, but he didn’t have that kind of reason to hunt Nana. And to go as far as where he went to stain her memory even after killing her… She must have been someone really special. Toshinori still holds her in high regards and can’t stand the idea of sullying her memory by hurting her grandson. After this fight, Toshinori is despaired to know where Shigaraki is, and probably hopes to talk to him, and ultimately, save him. We already know how her story with Toshinori will unfold, but I guess it’s gonna be as tragic as beautiful and inspiring. I can’t wait to know more about her.
