The Demon Dragon Slayer

Hyorei Oni is a demon dragon slayer. Like every dragon slayer her dragon disappeared.... At a very bad time as well. She had to wander alone.... Well not fully alone she had Frost ( her exceed )with her. While they were walking they run into a Fairytail guild member on a quest. Who then takes them under their wing and treats them like family. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This is the story of what happens when they were sent to the Fairytail guild under strict orders to only help, do missions, not to show her magic besides the ones instructed, and to not give away who she really is. But what happens when nothing seems to go as planed? Read to find out ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Warning: their is cussing, violence, and gore so if you don't like that skip over it ( for the violence I'll say before when it will be) or don't read. Disclaimer: I do not own Fairytail. If I did GaLe,NaLu, ErJa ( Erza x Jallal sorry I forgot there ship name ), Carla x happy , and lot of others would be together. Sorry if you don't support them. I'm not saying Grey x Juvia because this is a Grey x OC. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Warning number 2: I'm not really going with the plot like some characters might show up earlier than others and stuff. I will try to go with it but don't expect spot on stuff.
