Tolong jelaskan mengenai Familiar dari Daftar karakter The Familiar of Zero

Voiced by: Satomi Arai (Sylphid) / Yuka Iguchi (Illococoo)

is a 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.
