Not necessarily, but that's close to it. The main 13 I can produce are extensions of myself. However, dolls based on others are, obviously, extensions of their inspirations.

(The particular doll doll Bazett is looking at is currently reading the labels on some of the products and mentioning something to the other dolls about her findings. It's all in english of course, but Kreutzer's mun isn't really up for typing all of that up at the moment.)
