Shirley Fenette is a typical, all-around nice girl who is exceptionally friendly and loves her friends. She is a member of the swimming club. She admits to being infatuated with Lelouch since his enrollment on campus, but finds it extremely hard to get his attention. She has a habit of jumping to conclusions before people can explain things to her, particularly when Lelouch is concerned. Shirley was awarded 19th place in the 29th Anime Grand Prix for Favorite Female Character.
Shirley has a major role in the middle of the first season. After the Black Knights, led by Lelouch’s alter ego Zero, indirectly cause the death of her father during the Battle of Narita, Villetta Nu suggests that Lelouch may be involved with the Black Knights, so Shirley follows him and discovers that he is in fact Zero. When Villetta covertly follows her and attempts to arrest Lelouch, Shirley shoots her to protect him. She tries to write a letter about her feelings on the situation to Lelouch, only to throw it aside. Mao uses his mind-reading Geass to manipulate her into killing Lelouch, but she cannot bring herself to do so. To alleviate her suffering, Lelouch uses his Geass to erase Shirley’s memories of him. Lelouch expresses regret for having to do so, and even quietly suggests that he might have loved her. Shirley rediscovers her letter near the end of the first season, but cannot confront Lelouch about it because of the rebellion that takes place.
In the second season, Shirley’s memories, along with the rest of Ashford’s Student Council, have been rewritten by the Emperor, erasing her memories of Zero’s identity for the second time. Her affection for Lelouch has returned over the intermidiate year. Her memories are restored by Jeremiah Gottwald’s Geass Canceller.
After coming to terms with it, she comes to understand Lelouch’s motivations and forgives him after realizing that he is alone in his quest. She resolves to support him as the one true thing in his life, but runs into Rolo; when she mentions that she wants to help Lelouch reunite with Nunnally, he mortally wounds her. She confesses her feelings to Lelouch when he finds her, and dies in his arms despite Lelouch’s desperate attempts to command her to live. Her death was officially ruled as a suicide by a coroner.
