Kaeli, The Last Guardian

This is the Life of a girl named Kaeli Bright. The Ethereal Dragon Slayer. One that has a power hidden deep within herself, and one that she would know about the moment she got it. The member who made herself forgotten from existence and kept demons from wreaking havoc.

While on a journey to help keep this from happening, she was cursed. She has a darkness that will spread to others when she cares too much. Friendship is the cure to the curse.

With the help of Fairy Tail, she learns that trusting others is the key to keep the world from plummeting into darkness.

The forgotten member returns to Fairy Tail.
