It's the International Moron Patrol!
We don't actually act like this but it's funny to watch.
Reiko is a perfectly normal red-eyed, pointy-eared, sadistic little demon girl.
** Warning this is Hentai **Rosario + Vampire is anime about a teenage boy who by mistake is sent to a school for yokai ( Japanese for demon ). He befriends many female yokai, one of them is Moka. She is a vampire but she stays in a kind of human form as long as the rosary around her neck stays on. Once it is removed she turns into a blood sucking vampire. I hope you all enjoy the animation, and remember to vote!
