Not only their names are Kanade and Hibiki, but they have Saya's surname as well, I wonder why? I can see why Saya kept the surname Otonashi (she was adopted as a "teenager"), but why her nieces the same? To show they are related to Saya?

On the other hand, giving a look to the Japanese wikipedia article of the Blood+ characters, it seems like the little queens were voiced by Eri Kitamura and Akiko Yajima aka Saya and Diva's seiyuus! I wanted to put the link as a reference but sadly I don't how to put well a reference in an article, oh well....

About Kanade being the singer....well, perhaps is a generation switch? I think that BOTH girls will be singers, hehehe.
