Background / History

Long Kui's soul was sealed within the Demon Sword for a thousand years. When Xiao Se obtained the sword, the System altered her fate and memories: she recognized him as her “Royal Brother” in place of Long Yang. She immediately formed a deep familial attachment to him, while Xiao Se resolved to protect her from the sacrifice and separation she had suffered in her original fate 10 11.

As a Soul Body, Long Kui could not safely remain outside the Demon Sword without protection. Xiao Se promised to find a way to restore her body, while she became his constant companion through the Demon Sword Tattoo on his right arm 11 126. She later began cultivating the Returning Origin Soul Art, which proved especially suited to her soul state 19.

Long Kui's red personality, Hong Kui, surfaced when Xiao Se asked to see her transformed state. The two personalities initially shared one soul-body form: Lan Kui was gentle and reserved, while Hong Kui was bold and combat-oriented 18. They continued to assist Xiao Se throughout his travels, particularly in dangerous encounters involving magical beasts, Hai Bo Dong, and the Azure Lotus Core Flame 46 59 65 72.

Xiao Se and Long Kui held a simple marriage ceremony and temporarily restored her physical body for three days by merging their souls. This allowed her to experience physical sensations for the first time in nearly a thousand years 272. Much later, Xiao Se completed her resurrection using high-grade materials, restoring Lan Kui as Long Kui while Hong Kui remained part of their shared existence 429 430.

Appearance

Long Kui is a graceful young woman whose initially translucent body reveals her status as a Soul Body. She wears a Wide Sleeve Flowing Fairy Dress and can shift between blue and red forms 10 18.

  • Lan Kui — blue hair, blue attire, and blue pupils; gentle, elegant, and ethereal in bearing 18.
  • Hong Kui — red hair, red attire, and red pupils; her transformation also gives her a more mature figure and a fiercer presence 18.
  • Soul manifestation — can dissolve into blue or red light and return to the Demon Sword Tattoo 126.
  • Restored body — gains a tangible physical form following her resurrection, backed by the aura of a Six-Star Dou Saint 430 434.

Personality

Lan Kui is gentle, shy, quiet, and deeply affectionate toward Xiao Se. She is protective but worries about overusing her Soul Power, and she finds happiness in ordinary domestic acts such as preparing meals, embroidery, and staying by his side 11 15 19 26.

Hong Kui is Lan Kui's contrasting second personality: fiery, bold, teasing, and direct. She readily fights to protect Xiao Se and is far more assertive than Lan Kui, though she can become embarrassed in unfamiliar intimate situations 18 20 217.

Despite their differences, both personalities are devoted to Xiao Se. Lan Kui often moderates Hong Kui's impulsiveness, while Hong Kui acts when Lan Kui prefers peace or hesitates 20 88 442.
