Pheles is a lord who once loved and continues to love a human named Johan. To ensure they could be together forever, they created the most valuable treasure in Guze, known as the Reiji Maigo. This treasure grants eternal life to its bearer, the Mystes. Thanks to the Reiji Maigo, Pheles doesn't need to consume other humans' existence; she can sustain herself through Johan without risking his disappearance. During a fight with Sabrac, an assassin from Bal Masque, Johan was severely wounded. To protect him, Pheles sealed Johan within the Reiji Maigo. Unbeknownst to her, Sabrac had also placed the Silver into the Hougu at the same time. When the Reiji Maigo was lost, Pheles began searching for it everywhere using an Unrestricted Method called "The Wheel of Wind" (Kaze no Tenrin), which becomes a duplicate of herself when the target is found.
In the light novels, Johan takes control of Yuuji's body to persuade Pheles not to sacrifice the current Mystes to bring him back. Pheles agrees to her lover's wish before departing to unknown places. She shares a friendship with Wilhelmina, whom she once saved from a trap set by the Denizen Lord Sabrac. Pheles does not appear in the first season of the anime but shows up in the second season around the end of episode twelve during her search for the Reiji Maigo.
