>>2322702eh, you're talking about the adjectives though, I've never heard of an actual person (French or otherwise) having Blanc as a first name, it tends to be a surname, while Blanche is about as gender-neutral as Bianca, i.e. not really at all unless your parents were weird hippies or your country has no naming laws
buuut this is a goddamn pokemon game and the Japanese goof up western names all the time, so for all we know Blanche is a five-gendered android-fairy who sprouts a dick every half-moon when in the presence of dried unicorn droppings
