A mysterious person who claims to work for the Ministry of Civil Affairs, but is a "non-entity" on the Ministry of Civil Affairs' List. Yelan is said to be quite secretive and mysterious; while claiming to work for the Ministry of Civil Affairs, she's frequently absent from work most of the year. Despite this, Ningguang tolerates her general absence while Keqing appreciates her work, although the latter wonders as to where she gets her intelligence from. She employs psychological tactics to catch her targets and get all the information she needs from them. Outside of work, Yelan approaches life at a calm and carefree pace. She frequently enjoys napping whenever possible, but will adjust her schedule as needed for the day's tasks. The reason for this is because of her physical frailty, a hereditary trait within her family. When handling particularly troublesome cases, she tries to save up her energy to complete everything in a single go. In the presence of others, she is said to be very pleasant and polite. When alone, she's said to show a far different side of her as an extremely reliable, powerful and intelligent woman. She also has a high tolerance for spice, eating raw or dried Jueyun Chilis after deeming Xiangling's spiciest dish not enough for her. She dislikes sweets, claiming that they're too easy to get addicted to and disrupts focus.
