Fia's familiar, a black dragon said to be one of the Three Great Demon Beasts. It was saved by Fia from the brink of death and formed a familiar's contract. As the strongest of the demon beasts, it has an arrogant side, and often has a sharp tongue when it's time to talk about anyone other than Fia... Its hobbies are sleeping on Fia's stomach and updating the "Zavilia Purge List."
