When Rin Okumura - the half human bastard of Satan and exorcist in training- encounters the legendary Nyarlathotep, he gets transported to the world of Equestra.

Now Rin must find his friends and travel back to Earth.
Unfortunately, the door back is at the very bottom of Equestria's hell Tartarus. Now to get back Rin has to do what he does best. Killing more demons!

Not featuring Dante from the Devil May Cry Series :(

This is mainly a Blue Exorcist (manga) crossover with a Lovecraft antagonist.
