Her involvement in anime starts in ADV Films in Houston where she had some bit parts in Those Who Hunt Elves that involved about three hours of studio time. She did not hear back for some time until she got cast in Neo Ranga. A few weeks later, she auditioned and got her first starring role as Kaname Chidori in Full Metal Panic!. In Super Gals! Ran Kotobuki, she voices the title character who is a fun-loving teenage gal in a family of police officers. In Prétear, she voices main character Himeno Awayuki, a teenage girl who ends up living with two stepsisters and becomes involved in a magical girl fantasy. She also voiced teacher Yukari Tanizaki in the school life comedy Azumanga Daioh. In 2006, she was featured in a series of articles by IGN titled “Babes of ADV Voice-Over”.
Christian joined the voice actors who would regularly travel from Houston to record with Funimation in Dallas. She had supporting roles in Fullmetal Alchemist as guest character Psiren and later as the recurring character Wrath. She voiced actress Asako Kurumi in Funimation’s dub of Kodocha, and a lead role as Rico in the girls-with-guns drama Gunslinger Girl. In 2006, she voiced lead character Asuna Kagurazaka in the school anime Negima, which is about a boy magician who teaches at an all-girls middle school. Theron Martin of Anime News Network remarked that she interpreted her role much like Kaname Chidori on Full Metal Panic. She also landed the lead role of Tenma Tsukamoto in the comedy School Rumble, voiced the supporting role of Hitomi Kashiwa in Welcome to the NHK, and voiced the youthful-looking Mitsukuni “Honey” Haninozuka in Ouran High School Host Club. After Funimation acquired the dubbing rights for the long-running One Piece anime series, Christian was selected to play its lead female navigator Nami.
In 2007, the American Anime Awards nominated her for Best Actress for her work in Princess Tutu as the lead role of Ahiru, and Best Actress in a Comedy for her work in Desert Punk, Negima and Nerima Daikon Brothers, but lost to Mary Elizabeth McGlynn and Debi Derryberry, respectively.
