She gets along very well with Issei and asks for his autograph in Volume 11. Despite her affiliation with Vali, she was considered by Ravel Phenex to be Issei's contracted Magician, but initially rejected due to her status as a member of the Khaos Brigade. In Volume 16, Le Fay is officially made Issei's Magician because Vali's Team has been pardoned for their crimes, and Arthur requests Issei to consider taking her as his magician, with Issei accepting his request. It became official in Volume 17 when they established a 5-year contract, when the girls present requested to go on a shopping date with Issei, Le Fay also raised her hand, hinting at having a possible crush on him. In Volume 25, Le Fay quietly expressed some jealousy as she watched Issei's brides fight over him. Le Fay also assisted Issei when he was attacked by Meredith Ordinton to rewrite Issei's pervert personality with the Alphecca Tyrant and was also crucial to stopping Meredith, restoring Issei's original pervertedness that allowed him to defeat Angra Mainyu. After Issei became a Special-Class Devil, Issei acknowledged Le Fay as a good person and hoped she could remain as his contracted Magician, which Le Fay blushingly reciprocated, showing she has romantic feelings for Issei.
