Fairy Tail and Percy Jackson

Fairy Tail goes to Camp Half-Blood on a job, it seems that one of Zerefs deamons is targeting the camp. But here's the catch, they can't tell anyone who they are until the right time. At Camp Half-blood everything is peaceful they just finished the battle of Gaia. How ar ethey going to react to these new and strange campers?

Also Lucy not only has Celestial keys but all dragon slayer, reauip and (new) fairy form magic. She now is eaqual maybe even more powerful than Erza.
