I think, the Yorha androids all being dressed in, like, skimpy dresses (or overly body hugging catsuits during the start of C route) while at the same time being discouraged in expressing emotions due to it being “inefficient”, kinda helps to build on the contradictions within the struggle against machine lifeforms. Like, we have these sexily dressed but sexless characters characters Vs rusted wind up toys that are running the full gamut of human emotion. One example that immediately springs to mind is the scene where Adam is born, where 2B and 9S are surrounded by various simple machine lifeforms expressing their affection to each other, like there’s a parent rocking a crib and a couple fucking and, like, 2B and 9S keep insisting to eachother that they’re just repeating words and actions they don’t fully understand, which is later proven to be wrong as they begin to encounter and interact with machines in ways other than violence and begin to understand them as people, and then even later as 9S discovers the Yorha androids are built from reverse engineered machine lifeform cores.

There’s a lot of playing around with and subverting how a lot of media likes to do a sorta humanoid=personhood thing where the more attractively that person is portrayed, the more of a person they are.

—I go a bit tinfoil hat below—

Admittedly i might be me reading too far into it is that there’s also this recurring beat of 9S’ infatuation with 2B and how it pathologises into this sorta sex/death thing. There’s a bit close to the end of B route, (about the time you find out humanity’s been dead the whole time) where 9S keeps getting these intrusive messages from an unknown person confronting him about his desires. Stuff like, “you want to #### 2B, don’t you?” where it’s left ambiguous whether it means fuck or kill. So get you this sense of, like, how do I say it? Like, sorta second hand objectification. This annoying little twerp who (as far as he knows) has just met you is, like, oggling you and shit and the outfit 2B wears kinda help keep you aware of this.
