Background

Xuan Yu's first home was a small mountain temple inhabited by an old woman. The woman's scripture recitations repeatedly drew Xuan Yu out of dreams in which a black-robed figure built a mountain of skulls above a blood-red river. 196

The old woman later revealed that Xuan Yu was the seventy-seventh Calamity-Responding Person she had chosen. Her schemes led Xuan Yu to Ruyi Temple, where the cat lost a life through the old woman's manipulation of White Cloud Daoist and his alchemy. 243 302

Xu Qing established the Cat Immortal Hall with Xuan Yu as its Cat Immortal. Although he initially tried to invite nearby immortal families himself, Xuan Yu successfully assumed responsibility for the invitations and expressed her own preferences for the hall's offerings. 82 83

Appearance

Xuan Yu's true form is a black cat. She can transform into a young girl and can also possess suitable spirit-medium bodies, most notably the Silver Armored female zombie Sun Erniang. 112 183 250

• Black fur and a feline true form.
• Clear azure eyes and long eyelashes in human form. 246
• Usually appears as a black-clad girl when maintaining a human transformation. 381 445
• Can dissolve into black smoke when leaving a possessed body. 112
• Possesses Sun Erniang's tall Silver Armored zombie body to conserve incense. 181 250

Personality

Xuan Yu is playful, proud, and openly mischievous. She teases Xu Qing, performs unsettling jokes for visitors, and has little patience for people or animals that interrupt her conversations. 141 262 In battle, she is direct and feline in instinct, repeatedly favoring attacks at an opponent's throat until Xu Qing advises her to vary her targeting. 243

She is deeply attached to Xu Qing despite often maintaining a cool, aloof manner. She guards him during seclusion, offers him her newly condensed Demon Core without reservation, and worries about the danger he faces. 153 251 She is also notably frugal with incense, preferring possession over sustained human transformation even after the Cat Immortal Hall becomes prosperous. 250

Xuan Yu distrusts emperors because a previous emperor intended to refine her into an elixir. She strongly opposes Xu Qing becoming involved in imperial affairs and values the safety of the Cat Immortal Hall over palace prestige. 263 390
