Leivinia Birdway is the haughty genius girl that leads the Dawn-Colored Sunlight, one of the largest magic cabals in the world and the largest Golden-style cabal in Europe. She and her cabal have the final goal of eliminating the distinction between the Magic and Science Sides and rule over both of them. Despite her age, she's still a powerful magician with great knowledge of magic. Initially, she remained in the background of several incidents, but she started playing a larger role in the world's events after she and her cabal saved Kamijou Touma after he fell into the ocean during the end of World War III. She participated in several conflicts with the terrorist group known as Gremlin, but her manipulative nature also caused a fight between her and Touma.
