I think about this scene a lot and now I'm going to talk about it.
Reposting this from my Twitter Tomb
This moment really hit me when I first watched the 2021 anime adaption. Why? Because it was one of those rare moments with Anna showing herself being vulnerable.
Now, you could take this as 'If you don't get stronger Yoh, another man will take me and make me his wife' type of thing. Especially as this happens after Anna's run in with Hao. Hao drops a couple of comments about Anna being such a good choice for an Asakura bride, so this could definitely be it.
Anna knows Hao is strong. She plays it cool, but still understands what a threat he is. She isn't stupid.
Personally, I feel like Anna was intimidated by him, even if just for a moment. She was caught off guard when he caught her hand, something no one had done.
That's why I put in another option here. A mixture to the feelings Anna must have been feeling.
I feel like it could also have been Anna showing that she was worried Hao could 'take her' and use her. And I'm not referring to a romantic way. I mean to just use Anna for her power in order to get what he wants.
I say this as a Haona enjoyer too but we have fanfics for that.
If Yoh doesn't get stronger, then Hao could easily defeat him, take Anna and use her power for himself. Hao is so driven to achieve his goal to become Shaman King that he will do whatever it takes. He will use whoever it takes.
Look, I am a Hao fan. I love Hao, and I will forgive him for whatever, but I know what he would do in order to finally reach that goal of becoming Shaman King.
We know Anna is super strong and a badass. We love her for it. But in Osorezan Revoir, we saw the Oh-Oni take her and take advantage of her/her power. What if she was worried it could happen all over again?
And I mean not with Oh-Oni or other Oni's resurfacing. I mean being used again as a source of power.
I think a lot of us in the fandom can agree there is a lot more to Anna than what we saw during her fight with Hao.
Anna is Anna. But who is Anna? Takei, please show us one day
I feel like Anna knows it too, that there is so much more to her, and that is what is so terrifying. What if she is taken and used again like the Oh-Oni did? But this time it isn't on a snowy mountain away from the population, it is the whole world.
All those feelings; worry, sadness, guilt.
So when Anna says 'someone else might take me', I feel like it comes from an anxious and worried place. Like she needs Yoh to be stronger, she needs him to be there.
Anna needs him, she needs Yoh.
And there are some thoughts. If you made it through the long read, thank you.
These are only my head rambles so feel free to add your own points. All respectful please :)
P.S. The way the English dub f**ked this whole scene over and did Anna dirty, is my villian origin story.
