As an Anime-Only and a Hentai:

I am fucking disgusted that there is such little Rule 34 material of Overlord around, there's basically one doujin on H2R, 30 or so fanarts on R34.xxx.

C'mon, we have lolis, shotas, a trap, monsters, gentlemen, a succubus, a bisexual vampire, and the best of all, Papa Bones!
