Virgilia
She was the previous Endless Witch before Beatrice, and was also her teacher.
Her new name (having passed her old one to her student) comes from the Divine Comedy character Virgil, who guides Dante through Hell and Purgatory to Beatrice, who is his guide through Heaven.
She is a silver-haired witch with great powers, despite surrendering most of them to Beatrice with the title of the “Endless Witch”. Unlike Beatrice, Virgilia thinks that the powers of a witch should be used for good and not for selfish means.
She taught Beatrice the Endless Magic, and retired, believing that Beatrice would also devote herself for the people. At the same time that she was Beatrice’s teacher, she also served as the magician of Beatrice’s home. Because of that, Virgilia had come in contact with her with the position of a servant. It is said that this became her downfall, and invited Beatrice’s arrogance and recklessness
She may be linked to Chiyo Kumasawa.
She assists Battler during Banquet of the Golden Witch, helping him to come up with theories to counter the claims that Beatrice sets forth, though it is revealed in the end that her allegiances lie entirely with Beatrice, having worked with and secretly assisted her throughout the game in an effort to make Battler accept the existence of witches.
However, she ends up becoming Battler’s ally once again in End of the Golden Witch when Battler becomes the Endless Sorcerer. She is a dangerous opponent, as she can beat Beatrice in combat if not for a surprise attack. She is also somewhat bumbling as well.
