When I say "Female Metal Vocalist" what's the image you get inside your head? Close your eyes for a second and let it come to you.
Depending on the sort of Metal you listen to, what popped up was either the classic Rock look - jeans, leather, spandex, studs - or what seems to have become the uniform for Symphonic/Gothic Metal vocalists these days -formal gowns and corsets.
Of course the Japanese would have to do things a little differently, wouldn't they?
Step this way and let me show you what I mean.
Mary's Blood - Bloody Palace (2015)
Sticking fairly close to the Metal template so far. Lots of Black which is always very metal.
