I'd like to believe the modern Aigis slutposting came to be because someone saw Trinity Soul with how slutty Kanaru is and thought all robogirls are as slutty as her. But realistically it's due to that one animation Amateur made they fap to 24/7.

Kanaru is much more interesting with how the twist of her being a robot is hidden through most of the anime. Along with her desire for humanity transforming into pure lust.
