no one in dubs really pays attenetion on how to say japanese. i her that only the actreess voicing Yuuko got Kurogane's name the right way the firts time, with the proper inflections.
only a few jap dub's get names the right way. Genoen did a decent job on some, like in Samurai Champloo. AND on alot, they just licensed for subs, lie Loveless.
sometimes i think that TRC would have gone better if it was just licensed for Sub.
