Lenalee Lee is a 16-year-old Exorcist from China. Her parents were killed by an akuma when she was very young. Due to her ability to use the Innocence, Lenalee Lee was forced to become an Exorcist. Because she was separated from her brother - her single, remaining family member - at a young age, she went insane and had to be restrained due to repeated attempts of escape. During that time, she witnessed Rouvelier's forbidden experiments to create Exorcists artificially, who became a source of her fear. When her brother Komui joined the Order, her sanity was restored. She now fights for her brother as well as her friends as she now knows she has a home and family to return to. The Dark Boots, her anti-akuma weapon, takes the form of a pair of black boots and give her the ability to run at high speeds, walk on water, and use sound waves as footholds.
