At the very least, she looks like a young adult to me. There are a lot of characters that look young like her in manhwa and whatever. When I think about child, I really really don’t think she looks like 9-12 years old. Maybe 18-20 ish.
We can’t put what is considered “normal” to humans onto some other things, I mean- they are elves, they stop aging at like… 30 years old or whatever. they have the age span that is far larger than humans. Besides, they are fictional characters. You can just go and read something else if you don’t like it.











It really is peak, I love the anime, the manga.. though I’m not very satisfied with the ending because I was fully expecting Yato to disappear
