Lan Fan is one of two bodyguards for Ling Yao and the granddaughter of Ling's other bodyguard, Fu. She is notably quiet and deeply cares for Ling, often prioritizing his safety over her own. Lan Fan is a highly skilled fighter with the ability to sense chi, or the presence of a soul, allowing her to easily identify Homunculi like Envy, who possess multiple souls within their Philosopher's Stones. Although her exact age is never specified, Ling refers to her as a "girl," suggesting they are roughly the same age.
During a confrontation with the Führer, Lan Fan sustains severe injuries and sacrifices her arm to ensure both her and Ling's escape. Following this, she leaves with Fu to have an automail arm fitted. Six months later, she returns with a new automail left arm equipped with a retractable blade that extends from her elbow to her shoulder. She wields this weapon in battles against Gluttony and during the siege of Central.
