Well, this ecard turned out eligible for Ritona Raito's 'Sell it to me' contest!
This is from the anime, Blue Exorcist, or Ao no Exorcist, which aired pretty recently (April 2011). I myself haven't started watching in until late June, but I found that the anime series was pretty good (and I am hard to please sometimes XD).
The anime series is a supernatural/action/fantasy genre, and is appropriate for all ages. Though it is a pretty serious anime, there are many comdeic relief sections throughout the story line. There are 25 episodes in total.
I couldn't really explain the anime any better than the summary writting in AnimeList, so enjoy reading it below~
'The world of Blue Exorcist consists of two dimensions joined as one, like a mirror. The first is the world in which the humans live, Assiah. The other is the world of demons, Gehenna. Ordinarily, travel between the two, and indeed any kind of contact between the two, is impossible. However the demons can pass over into this world by possessing anything that exists within it. Satan is the god of demons, but there's one thing that he doesn't have and that's a container in the human world that is powerful enough to hold him! For that purpose, he created Okumura Rin, his son from a human woman, but will his son agree to his plans, or will he become something else...? '
Dedicated to Ritona Raito, the creator of the challenge!~
