Huohuo is a playable character in Honkai: Star Rail and an apprentice judge of the Xianzhou Luofu's Ten-Lords Commission. She is timid, anxious, and often easily frightened, which contrasts with her important duties as a spirit-calling exorcist. Despite her fearful personality, she is kind-hearted and determined to do her job well. Huohuo is closely associated with supernatural investigations, ghostly incidents, and the darker mysteries surrounding the Xianzhou Luofu.
