Familiars
- Sylphid (シルフィード, Shirufīdo?, "Sylpheed" in Geneon anime) / Illococoo (イルククゥ, Irukukũ?)
- Voiced by: Satomi Arai (Sylphid) / Yuka Iguchi (Illococoo)
- Sylphid is a female nature (Rhyme in Light Novels) dragon and Tabitha's familiar. Sylphid doesn't live in the Academy like other familiars because she is too big (as a dragon), so she stays in a neighboring forest. When Tabitha got captured, Sylphid escapes and notifies Louise and friends by assuming the form of a blue-haired girl named Illococoo who considers herself Tabitha's little sister in Season 3. Though she is sensible, she is sometimes childish. She promised to her "older sister" that she would not tell anybody about her ability to use nature magic, but Derflinger eventually foundout about her secret. Saito gets on both Tabitha's and Sylphid's good sides.
