I haven't, although I've read bits and pieces of other people's write-ups. I've bought the first few volumes of one of the other Kaori Yuki things (Godchild) and it wasn't quite working for me (my daughter rather liked it). Maybe I ought to try Angel Sanctuary?

She totally does ... ! Maybe if Nataku had been raised by a loving big brother, he'd be a bossy little thing, too!
