Background

Shen Yu draws Bai Zuo as his first free Character Card during the initial bus incident. The card presents him as a handsome black-haired youth whose presence carries suffocating malice, with an S-rank contract to the Weird Heart Gu. 2

Heart Gu’s power makes Bai Zuo exceptionally dangerous around humans: he can alter memories and cognition, reshape personalities, brainwash targets, and seize control of their bodies. Because the Weird must be fed malice or it will devour its Host, Bai Zuo is placed under long-term supervision and restricted from harming ordinary people without cause. 3 7

The City of Crime special scenario depicts a younger Bai Zuo operating in Ze Hai City as an “ordinary relationship consultant.” He lives frugally, spends much of his time hacking, and turns his own kidnapping by a trafficking organization into an opportunity to infiltrate and manipulate its hierarchy. 181 183 184

At 100% Character Perfection, Bai Zuo ceases to be merely a remotely operated Character Card. He develops an independent consciousness, complete memories, and free will; Shen Yu can no longer directly control him through mental power as before. 192 515

Appearance

Bai Zuo is a refined and handsome black-haired youth with a gloomy expression and a faintly morbid smile. His attractive, youthful appearance often contrasts sharply with the malice and pressure he exudes. 2 178

• His eyes are likened to black holes that swallow and contain malice. 188 440
• He has slender, pale hands and wears black nail polish. 174
• During the Lamp Mansion Festival, he wears divine makeup with gold patterns around his eyes and between his brows while posing as the Holy Prince. 24
• In the wasteland, he wears a black wide-necked shirt, tapered biker harem pants, and decorative streamers. 176
• When his hostility is suppressed, he can appear like an ordinary student on vacation or an “exquisite doll” devoid of emotion. 40 434

Personality

Bai Zuo’s original card profile calls him “vicious and black-hearted,” socially terrifying, manipulative, and a born villain. He treats people as tools when they are useful to him and shows little instinctive regard for their lives or autonomy. 2 11

He is fascinated by malice, conflict, and the ugliness concealed in human nature. He deliberately provokes people into revealing their worst impulses, seeing evil as something worth observing and cultivating. 47 186 270

Despite his cruelty, Bai Zuo is exceptionally intelligent. His observation and analytical ability allow him to predict opponents’ actions, identify hidden motives, and prepare contingencies far in advance. 40 252

Bai Zuo can also be playful, lazy, sharp-tongued, and casually demanding around Association staff. He enjoys games and evades paperwork whenever possible. 40 100 442 Over time, he becomes more capable of restraining his malice and acting within the Association’s rules, though this restraint is self-imposed rather than a change of heart. 372 1151

Abilities & Skills

Heart Gu and Mind Control

Bai Zuo’s core power comes from Heart Gu, his contracted pure-white spider Weird. Its silk can invade minds, ensnare hearts, and turn victims into conscious but helpless puppets. 2 28

• Alters memories, cognition, and personality; can brainwash targets or erase witnesses’ recollections. 3 4
• Controls bodies without requiring the target’s consent. 106
• Marks targets with spider silk and uses them as puppets, informants, combat assets, or disposable tools. 33 174 440
• Can manipulate crowds on a massive scale; the more people he controls, particularly powerful ones, the higher his practical combat ceiling becomes. 28
• Requires malice as sustenance. If Heart Gu is not fed, it will devour Bai Zuo instead. 2
• Initially performs poorly against unintelligent Weirds and lacks reliable direct offense when no controlled humans are available. 29 679
• Later learns to disrupt psychic force and Weird energy directly, allowing him to control nonhuman Weird entities and remove this former weakness. 679 1151

Ghost Domain and Spider Silk

Within his Ghost Domain, Bai Zuo holds overwhelming control over those inside it. Human targets can be immobilized or moved like puppets through invisible silk. 27

• Forms white spiderweb barriers capable of stopping ordinary bullets. 27 177
• Cannot rely on those webs against specially modified anti-web ammunition. 27
• Converts spiritual power into transparent spider silk to bind, suppress, and analyze mental entities such as invasive systems. 1479
• Eventually gains authorization to expand his Ghost Domain across an entire world. 1485
• Uses a vast web of controlled human mental power and Weird energy to create a wall capable of neutralizing Blood Tide. 1487

Psychic Techniques

• Mind Possession — Possesses and directs a target’s body. 11
• Mind Barrier — Protects him against mental attacks and torture. 122
• Descent into Malice — Injects malice into a target’s consciousness, causing them to sink into malicious thoughts. 174
• Mind Prison — Unlocked alongside Descent into Malice; its specific operation is not detailed. 174
• Mental interrogation — Invades consciousness spaces and memories to extract information, though doing so against powerful entities is dangerous. 511 515

Analysis, Observation, and Hacking

Bai Zuo possesses perfect Analysis, outstanding Observation, and outstanding Hacking from the moment he is drawn. 2

• Reads emotional fluctuations and hidden motives with unnerving accuracy. 252 270
• Predicts Weird behavior and builds elaborate contingencies during containment operations. 40
• Hacks systems, infiltrates networks, and can access private group chats without being invited. 100 183 243
• Exploits selfishness, fear, and conflicting motives to break coordinated opponents apart. 703 704

Physical and Offensive Capability

Bai Zuo’s early combat style relies primarily on control and prepared tools rather than direct damage. 29 As Heart Gu advances, he develops more independent offensive capability.

• Catches a sniper round barehanded. 122
• Uses spider silk to halt gunfire and slaughter armed Blood Feast members. 177
• Directs Heart Gu’s enlarged body and split spider forms in battle. 700 704
• Becomes capable of handling high-rank missions without relying on controlled contractors as weapons. 1151 1478

Restrictions and Supervision

Bai Zuo’s contract with Heart Gu, past conduct, and repeated misuse of mind control lead the Aberration Association to classify him as an unstable element. He is assigned Ji Wu as a supervisor and is not permitted to harm ordinary people without cause. 7 116

A shackle is placed on him to limit Heart Gu’s unrestricted Mind Control. The Association considers this necessary because Bai Zuo’s personality and powers make uncontrolled abuse of civilians highly likely. 106

After his recovery, rank advancement, and improved behavior, the Association gradually loosens its supervision. However, his most extreme abilities still require approval, and the elders remain prepared to restrain him if he abuses that trust. 1147 1485

Relationships

• Shen Yu / Chairman — Bai Zuo’s superior, former operator, and the creator of his awakened consciousness. Bai Zuo seeks his approval, reports major accomplishments directly to him, and regards him as a powerful but gentle authority. Shen Yu rescues Bai Zuo from Chang Jianing’s consciousness space. 192 251 515 679
• Heart Gu — His contracted Weird and primary source of power. Their survival and advancement are interdependent; Heart Gu requires malice, while Bai Zuo works to remove its weaknesses and raise its rank. 2 571 679
• Ji Wu — Bai Zuo’s long-term supervisor and mentor figure. Ji Wu enforces the Association’s rules, prevents Bai Zuo from treating members as tools, and repeatedly cleans up his messes. 7 11 116 448
• Xu Zhou — Initially regarded by Bai Zuo as a potentially useful weapon and subjected to brainwashing during a rescue. Xu Zhou later remains grateful to him, credits him with helping him choose life, and receives guidance from Bai Zuo. 89 691 1470
• Mi Lan — A junior colleague and frequent provocateur. Their rivalry escalates into destructive fights, though Mi Lan’s teasing also reflects familiarity with Bai Zuo’s weaknesses and recovery. 571
• Flying Bird A — A powerful rival with whom Bai Zuo has a hostile, competitive history. Bai Zuo once attempted to target Flying Bird A for his body, but Flying Bird A resisted. 33 1487
• Fu Zhang — A fellow high-ranking Contract Anomalist who dislikes Bai Zuo’s personality but respects his position and strength. 251
• Silver Willow — Bai Zuo’s apprentice, who publicly defends him when others discuss his alleged Humanity Code violation. 1350
