I was into VisKei when I was younger, more for the looks than for the music, but that seems par for the course for many VisKei fans.
I am a big fan of Janne da Arc which has its roots in VisKei, but despite moving away from that image, they still have that sort of reputation among the youth culture... I mean a lot of their music is like pop rock synth stuff now D:
I think Acid Black Cherry, the JDA vocalist's current solo project, is supposed to be more VisKei... but I'm not really a fan so much. :x
