(Y/N) (L/N) a very mysterious girl. She is a Fairy Tail member, but not just any Fairy Tail member, no she's a triple S-Class wizard, a Shadow God Slayer. She always wears a black cloak and hoodie, so nobody can see her face. Most people think she is a boy. She doesn't talk to other guild members or uses her magic, unless she needs to. During the Grand Magic Games she gets the attention of an certain Dragon Slayer, Sting Eucliffe. What will (Y/N) do when he tells her, that she is his mate? And who is this dark figure following her?
