It's clever and a little cruel, an insightful look into Langwidere's past and why she is the way she is.

This is deliciously creepy and cool. I love how Langwidere doesn't start out as a bad person, but her lack of contact with normal people, her uncle's example, and the rules of her own magic shape her into a person who regards the rest of the world's population more as a source of potential heads (or fleeting annoyances) than as people in their own right. I also like her ambiguous relationship to the heads - the way she treats them somewhat like pampered pets and somewhat like pieces of herself - and how each head changes her personality (and skin! how neat!) while she wears it, though something essentially Langwidere remains underneath the overlay.

Oh, I love your take on these characters!
...It's honestly pretty scary.
