I myself haven't seen much discussion about her, but that's not to say there hasn't been any. I personally think that the little girl in the igloo is actually Madotsuki's younger self. Which would make sense, if you think about it. If Madotsuki was ostracized as a child, then the could easily translate to her feelings of loneliness in a cold world. The fact that she doesn't wake up or react to much could also be a sign of Madotsuki's resignation to such a loneliness. That's just my spin on it, at least.

It's interesting that there hasn't been much discussion, I thought it was common knowledge around YN fansites who she was or something. It's also pretty interesting that she is shown dreaming. I thought she was the hat and scarf girl, minus hat and scarf. Like 'projecting' herself to block world.

Well, I'm slightly new to the game and the community, so it's not like I'm really aware of all that goes on. Your idea is interesting too, they do look pretty similar if you remove the hat and scarf.

I considered that maybe Mafurako AND Kamakurako were separate representations of Madotsuki feeling isolated and alternatively invisible, but I like >>3597's idea that Kamakurako is projecting all of the Mafurakos.
