Rissa Eucliffe is the older sister of Sting Eucillfe. Like her younger brother, she too is Dragon Slayer. When they were kids, the two siblings were separated from each other. As the years went by, Sting would come to forget about his sister, forget about the one person who took care of him. While Rissa, on the other hand, would spend years looking for him, feeling guilty about losing her brother. Sting was raised by the dragon Weisslogia and joined Sabertooth with Lector, while Rissa was raised by the dragon Luxanna and joined Fairy Tail.
