I mean, have you seen those outfits? They’re hot AF.
I do find it weird that in anime, maids do it all. They do normal maid stuff, they are super intelligence agents, they are inventors, and bodyguards and pilots and drivers… They’re also sometimes dragons or kitsune.
I have to assume it’s merely a Japanese trope within these fictions. One I saw recently explained that Japan just took one look at Western maids from Europe and became enamored with the idea and why there are maid themed cafes and such. But again, that was in an anime so it could just be a joke.
