Not this again. Just what don't you like about Angel Sanctuary? The character designs were incredibly detailed, to the smallest individualizing feature, costumes were breathtaking - a mix of Victorian and modern, with a dash of military and fetish, from demons to angels everyone looked gorgeous, Heaven and Hell never looked prettier, and God was a fuckin' giant computer. What the hell was there not to like?
tl;dr Fabulous shoujo manga is fabulous.
