Elizabeth is often called "Lizzie" for short.
She is voiced by Yukari Tamura in Japanese version of the anime, and by Cherami Leigh in the English version of the anime.
Elizabeth is a teenage girl with emerald green eyes. She has waist-long, golden-blonde hair worn in two big drills, save for a slightly curled cowlick.
Elizabeth often wears elegant gowns and a variety of headbands decorated with flowers or ribbons. Her accessories include gold earrings and low-heeled shoes.
Elizabeth is a extremely girly, energetic and deeply girl devoted to Ciel, who she loves with all her heart and wishes to see him smile again. She tries to only look cute in front of Ciel because of a comment he made about not wanting a strong and scary girl to be his wife when they were children. While it looks as though she can not hold her own in combat, it was revealed later that she is a fencing prodigy when she was about to be killed by Bizarre Dolls, much to Ciel's and Sebastian's surprise. It is subsequently revealed that though many, including a younger Earl Charles Grey, had believed that Elizabeth's older brother Edward was the rumored "Genius with a Sword," the true genius had been Elizabeth all along and she had concealed her abilities for Ciel's sake.
- Lizzy bears a physical resemblance to the character Mimimi from the The Doraemons series.
