Background / History

Illness and entry into the instances

Beiwei dropped out of school to recuperate from poor health, then continued entering instances to stay alive. By the time she meets Mr. 39 at Hope Factory, she is already a veteran player, despite being only seventeen 2 6 340.

Hope Factory

Beiwei searches the workers’ dormitory with Mr. 39, finding a dried flower, an old pen, broken glasses, and a rat-chewed sweater. When a mangled figure appears beneath the table, he pulls her out and locks the door 4.

She subsequently proposes an alliance, offering scouting and assistance in exchange for protection. Her petite, innocent appearance has made other veterans reluctant to partner with her. Mr. 39 accepts, mistakenly believing that she is as helpless as he feels himself to be 5.

Beiwei keeps watch while he rests and increasingly interprets his apparent composure as evidence of extraordinary strength. After Li Luohan dies, she loots his revolver and gold bar and gives them to Mr. 39. During the factory’s lethal quiz, his last-second answer saves her; she then helps fight the Headless Ghost 6 9 15.

Cinema and Orphanage

In the Cinema instance, Beiwei reunites with Mr. 39 and participates in the investigation alongside Wei Yanchi and Yue Xiamo. She angrily presses Yu Youzong to tell the truth about his abuse and abandonment of Zhang Qiuyue 34 36.

Assigned to the Orphanage kitchen, Beiwei initially tolerates the cooks’ insults but retaliates with concealed weapons when attacked. She shares observations about the setting with Mr. 39 and gives him stolen salt that she believes can repel evil 67.

After investigating a nearby village with Wei Yanchi’s group, she is severely injured when Wei Yunmo identifies the players as invaders. Anbers announces that she has died, describing her illness as beyond his ability to treat. She is present again when the instance restarts, with Wei Yanchi identifying that run as the fifth loop 81 83 85.

Joining Mr. 39’s organization

Beiwei’s Monastery reward—a USB drive containing incomprehensible code—becomes useful when 455 asks her to deliver it to technical specialist Huang Zhuowang. Hoping to meet Mr. 39 again, she requests admission to his organization and accepts 455’s warning that the only way out is death. She then insists on accompanying Huang to the Country Z operation 87.

She becomes an active teammate, handling communications during an infiltration and participating in later investigations. Her loyalty remains particularly focused on Mr. 39’s safety 91 104 260 262.

Treatment and Worldline correction

Beiwei receives treatment associated with Anbers and temporarily stays in Mr. 39’s castle. His domain is safer for her mental state than Anbers’s hospital, and Anbers’s aura protects her from its instinct-driven ghosts. During the Laboratory confrontation, she helps take wounded teammates to Wei Yunmo for treatment 168 169 175.

When the Worldline begins forcing major characters back toward their original fates, 730 identifies Beiwei as its first priority. In the original plot, she was supposed to die in her fourth instance from a sudden heart attack. The correction relocates her from the Arctic Base to a hospital but does not erase her memories or restore her former physical condition; 455 finds nothing wrong with her body 204.

Return to school

After Lunar New Year, Beiwei reports that she has passed her exams and can accept assignments. Mr. 39 instead tells her to return to school. When she asks how much she must learn before rejoining his team, he reassures her that she has always belonged. She resumes her education and receives an assignment to meet Liu Jiarui in G City and revisit the Wei Family Old Residence 340.

Appearance

Beiwei has a petite frame and a sweet, innocent-looking face, often contrasted with an expressionless or cold demeanor 2 5.

• Hair: Wears a very short wolf cut during the Cinema instance 34.
• Clothing: Appears in sportswear and later a rebellious punk outfit 34 252.
• Piercings: Has ear piercings, a lip stud, and an eyebrow stud; several accessories contain concealed pins 35.
• Physique: Has well-developed biceps and considerably more strength than her build suggests 87.
• During treatment: Wears a simple white dress without her usual accessories while staying in Mr. 39’s domain 168.

Personality

Beiwei is guarded, practical, and conscious of how players exploit one another. She understands that alliances are necessary but dangerous when supplies are limited, and resents veterans who dismiss others merely because they have cleared fewer instances 5 12.

Her loyalty to Mr. 39 combines gratitude, admiration, and protectiveness. Early on, she treats his unreadable expression as judgment and worries about proving her usefulness. Later, she challenges people she believes are threatening or taking advantage of him 9 15 249 307.

Her sympathy is selective. Although furious at Yu Youzong’s domestic abuse, she shows contempt rather than pity when Old Eugene dies, calling him useless and disloyal. She seeks Mr. 39’s approval without recognizing his discomfort with that response 16 36.

Abilities & Skills

Concealed weapons

• Uses hidden blades in her shoes and weaponized accessories 67.
• Her piercing jewelry contains pins that 455 suggests could be assembled into a weapon 35.
• This equipment takes advantage of the instance distinction between outside weapons and worn clothing or accessories 35.

• Identifies how vocational-school students could be exploited as underpaid factory workers 8.
• Uses the Orphanage’s food supply and tenant-farmer cooks to suggest an Industrial Revolution-era setting 67.
• Keeps watch, loots useful items, and relays Mr. 39’s instructions 6 9 104 262.
• Proposes a relationship-based explanation for the Love Triangle instance, though Wei Yanchi offers a different interpretation 260.

• Wei Yunmo — Attacks her during the Orphanage confrontation, but later helps care for her under Anbers’s supervision. Mr. 39 praises him for treating her well 83 176.

• 455 — Contacts and recruits her into Mr. 39’s organization, directs the delivery of her USB drive, and scans her during the Worldline correction 87 204.
