rare female Rhyme Dragon and Tabitha's familiar. Sylphid doesn't live in the Academy like other familiars because she is too big, so she stays in a neighboring forest. When Tabitha is captured during the third season, Sylphid escape and notifies Louise and friends by assuming the form of a blue-haired girl named who claims to be Tabitha's little sister. Though she is sensible, she appears sometimes childish, such as showing no embarrassment when first appearing in the Academy Court Yard naked in front of Saito and the others, because as a dragon she goes about naked all the time. Illococoo promised her "older sister" that she would not tell anybody about her ability to use shape-shifting magic, but Derflinger is aware of her true nature and ensures that the others become aware of it too. Sasha is a female Elf who was one of Founder Brimir's familiars – Gandálfr.

Despite already being a Gandálfr, Sasha was Lífþrasir as well, similar to her successor Saito Hiraga 6,000 years later. Sasha killed Brimir by stabbing Derflinger into his heart while he tried to kill off the elves for reasons not yet revealed as of the 19th light novel. In his defense, Brimir meant no harm to come to Sasha when he made her his familiar. Although her backstory was never mentioned in the animation. Other Brimir , was the first Void mage. In his youth, he was absent-minded genius not unlike Colbert. He made a pact with Sasha. He is considered a founder of the familiar system for a mage's protector, establishing Romalia with the assistance of his apprentice, and had three children that would flourish the royal families of Tristain, Albion, and Gallia. Humans from the Holy Land were exiled by elves borders. Retaking his homeland came with an unwilling decision to annihilate elves, as Brimir wished with all his heart to not have to commit such atrocities.
