Is Ao no Exorcist an Ongoing Series?

Someone on Answers recommended that I watch Ao no Exorcist, so I went onto AnimeFreak.Tv and saw that it was only 7 episodes long~! o.o I'm on the second episode (eheh, newbie.... >.>), so I wanted to know if it really is only 7 episodes long, or if it's ongoing. ^^;
