Coba jelasin Sasha dari Daftar karakter The Familiar of Zero dong

is a female Elf who was one of Founder Brimir's familiars – Gandálfr. She made a pact with Brimir to allow him to experiment on her but he instead made her his familiar, something Sasha was not pleased about. She was the person who created the talking sword Derflinger as well as the first wielder. 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.
