Background / History

Military career and reunion

Xu Jiao grew up alongside Xu Long and was fiercely competitive from childhood. She became commander-in-chief of the Southern Theater's Ninth Army Group in her early twenties; she attributed her rapid appointment to the deaths of previous officeholders rather than extraordinary aptitude 44 45.

After Xu Long survived Resident Evil, she called to warn him against reckless mission choices, particularly the newly released Kung Fu Hustle world. Later, when his school sent its seniors to the fallen zone, she contacted him during the journey and welcomed him into her camp upon arrival 12 41 43.

Flame Hell Beast poisoning

During the campaign, Xu Jiao personally responded when ten C-rank Flame Hell Beasts appeared in the warning zone and destroyed thousands of robots. The beasts surrounded her and blocked her escape until Xu Long's sniper fire opened a route to his armored vehicle. Once aboard, she ordered a return to camp; Xu Long then discovered a venomous wound less than a centimeter long on her calf 44.

The toxin attacked at the genetic level. Without suppression, it would age her cells and cause fatal organ failure within six months. Available medicine could preserve her life for decades, but her enhanced attributes would decline and she would lose the ability to undertake missions 45.

Rather than accept that outcome, Xu Jiao agreed to an experimental treatment with an estimated five-percent chance of success. Xu Long repeatedly injected his T-virus-bearing blood and used serum to interrupt failed fusion attempts. After hours of treatment, the Red Queen confirmed successful fusion and also discovered that Xu Jiao and Xu Long were not biological siblings 45 46.

Retirement

Although cured, Xu Jiao submitted her resignation without informing her superiors that the toxin had been cleared. She explained that revealing the treatment could expose Xu Long as a T-virus carrier, potentially leading to his capture for research or execution. Further frontline injuries would also be dangerous because of her newly poisonous bodily fluids 46.

After completing the handover, she returned to her hometown. She had bought an apartment opposite the family's old home, but instead moved directly into Xu Long's house. Retirement soon left her restless: she watched television, ate snacks, and occupied herself with Rice Bucket, eventually exhausting him through constant petting, day-long walks, and singeing his fur 45 47.

Appearance

• Bearing: Described as valiant-looking when receiving the newly arrived students as commander-in-chief 43.
• Face and build: Beautiful, with a striking figure and slender waist 43 46.
• Voice: Notably lovely, contrasting with her blunt teasing 12.

Personality

Xu Jiao maintains a serious, responsible demeanor before her subordinates but drops that formality around Xu Long. She teases him freely, boasts about her strength, and expresses concern through rough humor. Her protectiveness is practical as well as verbal: she warns him about dangerous worlds and provides extensive support for his deployment 12 41 43.

Her competitiveness coexists with caution. She refuses to attempt the B-rank assessment without confidence in surviving it, partly because of her command responsibilities. Faced with poisoning, however, she prefers a dangerous treatment to becoming powerless. Her eventual retirement also protects Xu Long's secret rather than simply removing her from danger 43 45 46.
