Yasashii Ryuu no Koroshikata (aka The Killing Method of A Kind Dragon) is a light novel and manga series by Tsumori Tokio and Katou Eriko. I don't know much about this series (and the description on Manga-Updates is only semi-helpful) but I do know that the art drew my eye.
This series has yet to be licensed for release in America. After seeing this art, one can dream.
