Background

Xia Wuyou’s actions were initially driven by her aunt Xia Ke'an’s illness. Desperate to secure help, she secretly contacted Spark and provided Serpent Coil operational information to Shen He, leaving her divided between her organization, her past, and her family. Her conflict became severe enough that she wept alone after passing along intelligence. 5 7

Xu Shi recognized that Xia Ke'an was Xia Wuyou’s central weakness and used the situation to bring her under his control. Even under pressure, Xia Wuyou’s initial response was not submission but a willingness to fight him to the death. 7

Her view of Shen He deteriorated after learning of the connection between Spark and Shark Tooth, while Xu Shi’s openness about his own schemes made him appear less sinister to her by comparison. 27 When Shen He later used United Will to control her, Xia Wuyou regained consciousness, rejected him, and chose Xu Shi’s side. 86

Personality

Xia Wuyou is disciplined, resolute, and highly mission-focused. Once she accepts an order, she discards distractions and acts without dwelling on the target’s morality or the operation’s justification. 49 157

She is nevertheless emotionally vulnerable where Xia Ke'an and Xu Shi are concerned. Her early guilt over betraying Serpent Coil and killing Chen Fang contrasts with her later certainty that she will serve as “the sword in [Xu Shi’s] hand.” 9 309

Her private demeanor is noticeably softer and more playful. She is openly affectionate with Xu Shi, jealous of his interactions with other women, and capable of comforting him when he doubts the reality of their world. 118 309 332

Appearance

Xia Wuyou is frequently associated with a form-fitting combat bodysuit and external exoskeleton equipment, later replaced by the specialized battle suit Suwei. 9 221

• Wears goggles with Suwei; when not in use, she keeps them in her chest pocket. 221
• Uses a trench coat to cover Suwei in public at Xu Shi’s request. 221
• Her hair can become disheveled during combat. 49
• Was described as pale while recuperating from injuries sustained against Cheng Gujian. 309

Abilities & Skills

Gravity Manipulation

Xia Wuyou manipulates gravity in combat, specializing in direct confrontation and battlefield control.

• Uses sudden reductions or intensifications of gravity to interrupt an opponent’s movement and attack rhythm. 164
• Can envelop herself in her Gravity Domain and float to evade high-speed attacks. 322
• Her gravity-based abilities are ineffective against mental-power effects such as Xu Shi’s Malice Entropy. 156
• Her post-Sea God breakthrough produced an ability likened to “Collapse,” far surpassing her earlier gravity manipulation. 272

Gravity Domain

Her domain makes her a vanguard-style killing machine and gives her a major advantage in close-quarters combat. 9 164

• Alters local gravity to pressure, disorient, and hinder opponents. 164
• Supports close-range combat against opponents of comparable or greater rank. 164 290
• Could not decisively overcome Gu Yi’s specially modified anti-gravity-resistant mecha, resulting in a draw. 322

Combat Proficiency

As a Field Operations Department leader, Xia Wuyou is trained across multiple combat disciplines rather than relying exclusively on her Ability. 49

• Primarily excels at close-quarters fighting. 49
• Competent with firearms despite considering them a weaker area. 49
• Killed Chen Fang with a single precise strike. 9
• Held Cheng Gujian—an SS-class opponent—long enough for Wen Shengkui to intervene, though she acknowledged that Cheng had not fought her at full strength. 290 309
• Fought Gu Yi’s advanced mecha to a stalemate. 322

Leadership and Instruction

Xia Wuyou takes on increasing responsibility within Serpent Coil’s Field Operations Department.

• Handles many of Director Du Wei’s duties while being prepared as his successor. 143
• Becomes chief instructor of the training camp. 321
• Mentors Pan Feng without shielding her from internal competition, requiring her disciple to earn advancement through her own ability. 322
• Agrees to provide Pan Feng with advanced mecha-piloting instruction. 323

Equipment

• Suwei — Specialized battle suit and exoskeleton system designed by Jiang Chengcheng and named by Xu Shi. Its nano-level internal integrated circuits reduce weight and improve reaction sensitivity. 221
• Alloy Battle Blade — Issued alongside Suwei before the Hualan Empire’s expedition against the Sea God. 221
• Goggles — Part of her Suwei equipment. 221
• Upgraded Suwei systems — Suwei receives repeated upgrades over several years as Xia Wuyou becomes increasingly compatible with it. 322

Relationships

• Xu Shi — Superior, partner, and the person Xia Wuyou ultimately chooses over Shen He. Their relationship develops from coercion and dependence into mutual affection; they share their first kiss after Xia Wuyou realizes her feelings. 86 118
• Xia Ke'an — Aunt and one of Xia Wuyou’s most important emotional ties. Xia Wuyou’s initial collaboration with Spark was motivated by Xia Ke'an’s health, and the two later cooperate to uncover the truth behind Refraction. 5 12 73
• Shen He — Former secret contact and ally. Xia Wuyou once gave him Serpent Coil intelligence, but breaks with him after he attempts to control her through United Will. 7 86
• Dongfang Xiao — Niece. Xia Wuyou protects her during Cheng Gujian’s palace attack on Xu Shi’s orders. 290 291
• Pan Feng — Disciple. Xia Wuyou trains her rigorously and later agrees to teach her advanced mecha piloting. 322 323
• Gu Yi — Friend and competitive rival in the debate between exoskeletons and mecha; their spar ends in a draw and earns mutual respect. 321 322 323
• Jiang Chengcheng — Ally and Suwei’s creator. Xia Wuyou values her safety and relies on her continuing equipment upgrades. 221 323
• Shen Qin — Fought Xia Wuyou in an onboarding assessment; both secretly held back and staged their defeat. 121 122

Story Role / Major Arcs

Spark Infiltration

Xia Wuyou secretly meets a Spark representative and provides Shen He with information about Serpent Coil operations. Her betrayal is rooted in Xia Ke'an’s condition and leaves her conflicted rather than fully committed to Spark. 5 7

Chen Fang’s Death

Confronted by Chen Fang over false intelligence that led to his team’s destruction, Xia Wuyou hesitates out of guilt but ultimately kills him in a single strike. Xu Shi recognizes her combat value afterward. 9

Break with Shen He

Shen He attempts to use United Will to control Xia Wuyou during an escape. Xu Shi counters the control, allowing Xia Wuyou to regain herself; she attacks Shen He and formally severs their connection. 86 87

Serpent Coil Leadership

As Du Wei’s retirement approaches, Xia Wuyou assumes many of the Field Operations Department’s responsibilities and is treated as his likely successor. 143

Sea God Expedition

Xia Wuyou receives Suwei and an Alloy Battle Blade for the Hualan Empire’s campaign against the Sea God. Under Suwei’s enhancement, she pushes her Ability close to SS-class and develops power beyond her prior gravity manipulation. 221 272

Defense of Dongfang Xiao

Sent to secure the Imperial Palace, Xia Wuyou protects Dongfang Xiao from Cheng Gujian and fights the SS-class Grand Duke directly. She buys the time needed for Wen Shengkui’s arrival, sustaining injuries that require recuperation. 290 291 309

Mecha Rivalry

As Serpent Coil expands its mecha program, Xia Wuyou challenges Gu Yi to test mecha combat against an Ascendant’s exoskeleton and Gravity Domain. Their contest ends without a victor, providing Jiang Chengcheng with data to upgrade both Bright Sight and Suwei. 321 322 323

Trivia

• Xu Shi names Suwei after a tiger, contrasting it with his habit of calling Xia Wuyou a “little kitten.” 221
• Xia Wuyou is one of the few people Xu Shi trusts to contribute through direct combat rather than long-term planning; she considers herself suited to fleet leadership and eliminating enemies. 310
• Her ability to hold her own against Cheng Gujian astonishes Dongfang Xiao, who had previously regarded Cheng as nearly unbeatable. 290
