Exorcist tail (blue exorcist x fairytail fan fic)

(I dont own fairytail or blue exorcist or should I say a no exorcist)

So you know I'm not doing y/n anymore right?

Well this is no different but I will try some other time!

Any Who Cora vermilion is the last known relative to the original leader of fairytail

She is a demon slayer like gray but unlike gray is a fairy demon slayer,celestial demon slayer and a elemental demon slayer

Sorry I like demon slayers!

Anyway her and gray get a job request I protect a school from demons and they are required to take the classes

The others think it's cool
And "decided"to tag along after erza recommends it

What happens when they meet the true cross students
