I am surprised that this series doesn't have a catagory yet...
So lets start one!
The series is called Ao no Exorcist, Blue exorcist, or Ao no Futsumashi
At first it might seem like it has a pretty average plot, (Demons, school, exorcists) but at the same time it is very entertaining and has nice depth as the series continues. (Not to mention amazing artwork)
Curently its on the high end of my favorites list (up there with Defense Devil, Zetman, and Shin Angyo Onshi)
Give it a try!!! ^-^

Mostly I just got rid of lots of bothersome text...
But I also smoothed out some pixelation and messed with the brightness/contrast.

Thank you for viewing!!!
