Jingliu is a supporting anti-heroine and a playable character in Honkai: Star Rail. She makes her first appearance in one of the Companion Missions, "Frosty Blade's Trial".
She was once a swordmaster in the Xianzhou Luofu and was also the teacher of Jing Yuan and Blade. After succumbing to Mara and losing her sanity, she manages to escape from Starskiff Haven in the year 7380, and is pursued by Jing Yuan before he finally confronts and defeats her. It easily froze all the Cloud Knights sent there. However, she managed to survive her encounter and traveled the galaxy outside of Luofu for centuries. At an unknown point, Jingliu makes a "deal" to restore her sanity, and Luocha suggests it is Mara's solution.
