Johan  

Eternal Lover, ヨーハン

In his youth, the Reiji Maigo was once known as Pheles, who killed her father in an attempt to gain eternal life through the Power of Unrestraint. She then fled with Johan and raised him as her own, expecting his heart to become corrupted like hers. However, when Johan grew older, he surprised Pheles by asking for something that caught her off guard - a sign that he had fallen in love with her. As they became an Appointed Couple, the Reiji Maigo was created to ensure their eternal life together. After his rebirth as a Mystes, Pheles trained herself and became a powerful master of Power of Unrestraint, enhanced by her ability to sense the power of existence.
