The Dragoness (Meliodas x Fairy Tail! OC x Zeldris)

The Dragoness of Fairy Tail, Yelena Carmella Ceres. She is an S-Class mage with the potential to be one of the Ten Wizard Saints due to her incredible prowess. A dragon slayer with two elements, fire and ice. She was to be respected and feared by all who dared to make an enemy out of Fairy Tail.

Her origin, however, was a mystery that not even Yelena herself knew much about. That will soon change when one day, there was a mission that is a few months old from another country called Britannia. Being the only S-Class mage available, Yelena took it and sailed forth to gather the Seven Deadly Sins.

But ever since she met the Leader of the Sins, Meliodas, and has been getting dreams of an individual who highly resembles him, that's when her life began to turn upside down as her origins began to unravel.
