And the angel thing, I think I read somewhere on Gwendel's site that it was the name of an angel...lemme put it here...
Hello Minna san!! According to Lucy Aspra (especialist in angels) the info is correct. It is the original message and the traduction:
Hello Rosalía: Indeed, according to the Ozar Midrashim II, Klaha is one of the many guardian angels of the portals of the Wind of the South."
I searched this long time ago, and I still think is a sweet coincidence. An another coincidence was the angel's image: is a man in blue, black and white, singing... remainds me a lot setsubou colors....
