OMG LORE UPDATE

The fact we can see an even smaller anya and her most likely mother, and when you see the dress from the back it looks like a hospital gown which makes me think that she was always stuck as an experiment maybe her mother was too, also the fact that in these panels you can't clearly see her face which could be two reason, a choice the Mangaka took just so everything isn't spoiled (most likely the case) or it's because Anya can't clearly remember her mother's face because she might have disappeared when she was younger
