In japanese, black belts are called "karate champions".
And the beauty class are known for using cute pokemon.
If you are a sane person, crediting medical science means that she had plastic surgery done to look beautiful.
The source of this confusion comes from martial arts champions being the furthest away from being cute, and there is only 1 sprite for black belts. In other languages, they even changed what she did earlier, but keeping this implication of her doing a rough job that required strength, like a taekwondo fighter, or a pokemon breeder (basically a farmer).
This is also shown with the "Brains and Brawn" duo NPCs, that uses a black belt and a psychic sprite.
Another detail that points to this NOT being about transgender is this same NPC talking about how she used to be a black belt a mere half a year ago, which is a very short time if you try to tackle this angle.
