Eve Genoard Walken
The most powerful Magical Girl
Born into a wealthy family in Lichtenstein, she excelled in school. She was beautiful, talented, athletic, smart, and witty. Everything the local boys wanted. She was also a lesbian. She fell in love with the transfer student Yuko no Fujiwara, and her involvement with her got her captured by a suicide cult, planning on raping and sacrificing her. Kairi, Yuko, and Nikol saved her life, and taught her about magical girls. Eve soon became one, and a quite powerful one at that. She started by murdering her brother, burning him to death through his immortality, for giving her to the cult. When she got home, she murdered her abusive parents. She and Nikol later went to Switzerland to rescue her sister from their abusive grandparents, who had sealed a witch inside of Lilianna Genoard permanently. They saved her and kept magic a secret. When Walpurgis attacked, Nikol transported Eve and her sister onto the plane Claire took out to America. He and his wife adopted them, and took Eve on as his apprentice.
Throughout the years, Eve became the second best assassin in the world, and the most powerful magical girl by far. When Aya was dispatched to stop her wanton assassinations, Eve killed her and was made head enforcer. She now lives with her sister in San Francisco, dealing with the local witches and watching over the magical girls.
