I am so glad that you liked my essay. I am really into that pairing, and I am hoping that I have managed to understand it, and make other people understand the charm of it too. I don't know if there's generally sexual tension between siblings, I am a lone child, but between these two, there is. Their relationship goes from gentle and loving to violent and dysfunctional, and it IS fascinating.

As for Angel Sanctuary, you really need to read the manga. The anime is good, the manga is brilliant.
