Cui Ciyou

Biodata

Power Progression

Background

Cui Ciyou lived on Earth under the shadow of an abusive, gambling father, debt collectors, and his mother’s exhausting attempts to support the family. Cynical about fictional ideals of salvation, he nevertheless risked his life to push a young girl out of the path of an oncoming vehicle. His final thoughts were of his mother and whether she would be able to live without him. 1

After his death, the Human God identified him through Future Sight as a foreign variable—a “BUG” whose unusual fate could disrupt the established course of the Six-Faced World. 1

Cui awakened in a primeval forest with an enhanced body but few supplies. He survived by applying survival knowledge, making fire with a bottle opener and flint, and adapting quickly to the world’s dangers. His first battle against three Assault Hounds awakened Perception and established his overwhelming physical advantage. 3 4

The Human God later claims that an unimaginably great power transported Cui’s body and soul together without changing his appearance. Unlike Rudeus, whose spiritual form reflects his former-life self, Cui’s physical and spiritual bodies are synchronized. This explanation distinguishes his arrival from ordinary reincarnation, although the responsible power remains unidentified. 341

His memories of Earth initially cover only two seasons of the anime, rather than the full original story. After awakening his Parallel World Ability, memories from an alternate self provide much more complete knowledge of the novel and its underlying conflicts. 530 556 557

Appearance

Cui is a tall, lean young man with a youthful, delicate-looking face that contrasts with his intimidating strength. His unfamiliar appearance and clothing immediately mark him as an outsider in the Central Continent. 6 27

• Flowing black hair, later described as reaching his shoulders. 27
• Black eyes and narrow phoenix-like eyes. 6 27
• A “baby face” that belies his resolve and combat ability. 3 27
• Initially wears a black hoodie, white T-shirt, and black casual pants from Earth. 3
• Bears a faint scar behind his left ear from his former life. 1
• Continues favoring ordinary dark casual clothing even after becoming a famous noble, explaining that dark colors do not show dirt easily. 500
• His slender sword, unassuming appearance, and lack of visible Battle Aura cause the Sword Sanctum’s fighters to underestimate him. Gal Farion instead perceives an unsettling emptiness resembling a black hole. 573 574

Personality

Cui initially presents himself as cold, cynical, and emotionally detached. His experiences on Earth left him distrustful of narratives that glorify suffering or promise rescue. Yet his actions repeatedly contradict his self-protective rhetoric: he dies saving a child, intervenes to save Carl’s caravan, and refuses to abandon the starving Ghislaine. 1 9 23

He is highly analytical and pragmatic. Faced with an unfamiliar world, he prioritizes water, food, shelter, language, combat training, and access to books. He studies people, social hierarchies, sword styles, magic theory, and political geography as information necessary for survival and independence. 5 7 13 29 44

Cui values promises and responsibility despite claiming indifference. After accepting employment from the Boreas family, he resolves to fulfill his duties as a tutor rather than abandon a difficult student. 31

His protective instincts increasingly become a conscious principle. He initially refuses Philip’s proposed marriage alliance because Alice should not be used as a political bargaining chip, and he promises to help reunite Philip with his sons without demanding political advancement in return. He also commits to employing Lilia and helping raise Aisha despite possible scandal, regarding a vulnerable mother and child as more important than his reputation. 83 151

As a leader, Cui prioritizes loyalty, kindness, dependability, and principle over ability alone. His invitation to Counter Arrow offers a stable future without pressuring its members to abandon their current adventuring lives. He is also comfortable declining noble privileges, choosing the university’s common dining hall rather than its exclusive noble floor. 399 484

His growing warmth coexists with teasing, showmanship, and domestic awkwardness. He enjoys playful exchanges with companions, uses cooking to win over his Beastfolk hosts, and occasionally indulges in deliberately dramatic declarations. In family disputes, however, his usual composure gives way to anxious explanations and unsuccessful attempts to soothe his wives’ jealousy. 280 505 516 577

Cui’s desire for strength is ultimately tied to protecting others and changing an uncertain future rather than accumulating titles. He is willing to acknowledge tactical shortcomings, as when Alice and Ghislaine defeat him together. Although he initially tries to shoulder threats alone, his wives’ concern and future information eventually persuade him to discuss the Human God’s danger with his family. 151 560 565 566

Beneath his confidence, he remains deeply affected by separation from his mother. During a severe fever, he calls for her in Chinese, exposing grief and vulnerability that Alice and Sylphy comfort without understanding his words. 219

Abilities & Skills

Enhanced Physiology

Cui’s transmigrated body possesses exceptional strength, speed, coordination, durability, pain tolerance, and regeneration.

• Can leap nearly two meters with minimal effort and land without significant impact. 2
• Killed three Assault Hounds in under a minute through punches, a neck break, and a kick that snapped a spine. 4
• Recovers from wounds at an abnormal rate; bite wounds that should scar heal completely within days. 5 30
• Possesses enough raw power to split boulders, but ordinary weapons can break under the recoil. 19 20
• Reaches a sustained Sword King-level physique through continued growth and training. 155 203
• Later possesses physical toughness comparable to King- to Emperor-level monsters, with Mental Power reinforcement allowing brief Lower-Tier World Power–level force. 491
• Is not invulnerable: Orsted shatters his sword and guard, breaks his bones, and hurls him through several trees after his Mental Power is depleted. 210

Perception

Perception is Cui’s combat-sensory state, apparently supported by Mental Power.

• Transforms his vision into a black-and-white world of energy-like points and lines. 4 18
• Makes enemy movements appear slowed and allows him to read attacks, follow-up intentions, timing, and trajectories. 4 18
• Lets him effortlessly counter Dak’s attacks despite his limited formal swordsmanship. 18
• Does not replace technical knowledge against truly skilled opponents. 16 44
• Reveals muscle movements, breathing, Battle Aura circulation, and likely follow-up attacks during his confrontation with Gyes. 287
• Can be used to survey an area for captives and to inspect unusual weapons and magical structures. 358 377 449
• Adapts Sylphy’s environmental-sensing practice into a Mental Power technique, detecting differences in density and locating empty space behind a sealed chamber’s wall. 540
• Supports anticipation of Gal Farion’s attacks and makes the Sword Emperors’ blades appear slow during later training. 578 579

Magic Nullification

Cui suppresses supernatural energy around himself, initially as a passive field and later through deliberately controlled applications.

• Nullifies Battle Aura, even when it has already been activated. 6 9
• Extinguishes incoming spells before they reach him and can prevent magic from forming nearby. 9
• Initially has an estimated effective radius of three to five meters; later reliably covers a sphere with a roughly ten-meter radius. 9 10 203
• Makes him especially dangerous against mages and aura-dependent combatants in close quarters. 9 44
• Cannot generate his own mana or Battle Aura, though he later learns to manipulate externally supplied mana for magic. 20 96 334 540
• Is fundamentally an application of Mental Power and can consume or overload that resource at high output. 20 407 582
• Can be suppressed to permit magical experiments; forgetting to do so destroys a valuable mana crystal. 96
• Provides a safeguard against unstable experimental magic by stopping runaway mana. 96
• Removes excess, stagnant magic from Migurdia farmland, improving the soil’s prospects for cultivation. 230 465
• Can suppress manifestations of blessings and curses. He helps Zanoba control his destructive strength, lifts Pax’s appearance curse, and later gives Elinalise a curse-suppressing bracelet. 355 357 358 487 505
• Erases a ten-meter-wide safe passage through a magically driven sand wall. 420
• Requires maximum output to fully neutralize the Dragon King Sword’s gravity magic; passive suppression is insufficient. 451
• Can be narrowed, expanded, or released intermittently for precise combat timing, including a three-foot field used against Gal Farion. 575 578 579
• Does not erase sword technique, physical momentum, or an opponent’s bodily strength. Skilled fighters can attack around its range, exploit its activation timing, or coordinate physical attacks to counter it. 565 578
• Can cancel Orsted’s magic power at maximum deployment, but doing so expends all his Mental Power during the later group confrontation. 582

Mental Power

Mental Power is Cui’s mysterious internal energy source. He initially suspects it underlies his physical enhancement, Perception, regeneration, pain resistance, and Anti-Magic Field; later accounts identify his nullification, recovery, Telekinesis, and Pressure as applications of the mind. Its ultimate origin remains unknown. 30 407

• Increases gradually after being exhausted and fully restored. 32
• Can be channeled into sword attacks as an alternative to Battle Aura. 47
• Enabled Cui’s Sword King-level slash. 47 48
• Severe overuse causes dizziness, nausea, mental agony, and near-total exhaustion. 48
• Can synchronize and calibrate another person’s mental control, assisting Roxy’s development of silent casting. 95
• Is cultivated through meditation and refined through Telekinesis exercises involving heavy objects. 407
• Can reinforce his entire body, accelerate irregular evasive movement, and control his descent when conventional magic is suppressed. 357 491 578
• Can be concentrated at a sword’s edge or tip as “sword energy,” focusing force rather than displaying diffuse Battle Aura. 576 578

Mental Shock, Telekinesis, and Pressure

Cui develops direct offensive and manipulative uses of Mental Power beyond Perception.

• Mental Shock — Briefly disrupts an opponent’s mind, causing dizziness and momentary helplessness. Its first clear use creates the opening needed to rescue a hostage from Giles. 278
• Telekinesis — Moves objects without physical contact. He hurls debris and Giles’s fallen sword, wounding the North Saint in the shoulder. 278
• Mental Pressure — Projects an intimidating mental presence over multiple people. In a guild confrontation, it turns a crowd’s greed into fear and leaves the receptionist physically weakened. 298
• Repeated use of newly awakened abilities initially leaves him pale and drained, prompting dedicated practice during the Great Forest’s rainy season. 278 289
• Mental control remains usable inside Pax’s trap even when wind magic cannot form. 357

Swordsmanship

Cui combines overwhelming physical ability with technical study from the North God and Sword God styles, later incorporating Water God Style and a Mental Power–based approach of his own.

• Perfectly copied Dak’s North God Style Basic Stance after seeing it once. 17
• Learns North God Style principles of deception, adaptability, terrain use, and victory by any available means. 17 19
• Receives systematic Sword God Style fundamentals from Ghislaine, including grip, footwork, swings, slashes, and thrusts. 37
• Struggles with the instinct-based teaching approach of the Sword God Style and supplements practice with library research. 37
• Can use the Soundless Sword, a Mental Power–based Sword of Light, and a Sword King-level strike without Battle Aura. 47 48
• Combines intermediate North God and Water God techniques with Sword God Style moves; regards Water God Style’s rational and logical emphasis as particularly suitable for him. 142
• Rapidly learns most of the Sword God Style moves Ghislaine can teach, though she identifies Saint-level techniques as the limit of her instruction. 155
• Combines Beyond the Sword of Light with Magic Nullification to sever Orsted’s arm. 210
• Develops a precision-oriented method that exploits gaps, timing, and weak points rather than simply opposing greater force. He redirects Gal Farion’s God’s One Slash with an upward flick against a vulnerable point of the blade. 575 577
• Breaks both Sword Emperors’ weapons with one focused strike and later marks Gal’s Elegant Dragon Sword with concentrated Mental Power. 576 578
• Learns every Sword God Style technique beyond Sword Saint rank through King and Emperor rank during his Sword Sanctum preparation. His understanding of speed shifts from pursuing an attack to anticipating it. 579
• His demonstrated ability against Sword Emperors and Gal does not itself constitute an explicitly conferred Sword Emperor or Sword God title. 576 579

Magic Theory and Spellcraft

Although Cui lacks an internal mana reserve, he can direct externally supplied magic power through studied models, crystals, scrolls, and magical circles. His early belief that magic is unavailable to him is therefore superseded by practical spellcraft that does not require him to generate mana himself. 44 95 96 540

• Magic models — Studies spells as structured processes of mana flow and elemental combination. His mental guidance helps Roxy overcome ingrained dependence on incantations and achieve Advanced-level silent offensive casting. 95
• Blue Stream Blade — A narrow, highly compressed waterjet inspired by industrial waterjet cutting. It cuts thick iron armor, can be shaped and guided, and is designed for fast, efficient single-target combat. Its strength depends on finer control and greater Mental Power as well as its mana supply. 95 96 203
• External power sources — Uses Roxy’s mana during experiments and obtains mana crystals from Philip. Later activates a prepared Light Spirit scroll by linking it to a crystal. 96 540
• Teleportation research — Studies ancient circles to prepare for the Displacement Incident and later uses a large household circle to connect distant family members. 155 199 487
• Summoning research — Collaborates with Nanahoshi on magic-circle experiments and considers combining summoning and teleportation principles to interfere with higher dimensions. 506 508 516 487
• Healing experiments — Previously injures himself while experimenting with healing magic, leaving Roxy protective and reluctant to revisit that field with him. 155

Clairvoyance Demon Eye

Cui acquires and integrates the Demon Eye known as Clairvoyance. It is activated by supplying magic power rather than drawing on an internal mana reserve. Its large cost, together with the mental strain of Dragon Saint Battle Aura still affecting him, initially makes frequent use impractical. 266

Parallel World Ability

Repeated encounters among parallel versions of Cui accumulate until the tenth collision breaks the barriers separating their worlds. Cui identifies the resulting ability with Byakuran Gesso’s Parallel World Ability and receives an influx of alternate-self memories. 554 555 556

The information provides fuller knowledge of Jobless Reincarnation than his own anime memories, allowing him to reinterpret the Human God’s actions and plan against his information advantage. The initial influx is overwhelming, and Cui notes that his counterpart processes the same information with much greater ease. The demonstrated effect is access to parallel-world knowledge; the full limits of the ability remain unexplained. 556 557

Learning and Teaching

Cui has exceptional memory, pattern recognition, and language-learning ability.

• Learned Human Common Tongue from isolated words and gestures to functional everyday communication within months. 7 13
• Treats language as a practical tool for gathering knowledge about the world’s laws, geography, power systems, and society. 13
• Uses House Boreas’s library to study literacy, history, geography, politics, religions, races, magic, and the three major sword styles. 29
• Tailors lessons to his pupil’s interest in combat, using swords and battles to teach arithmetic, history, reading, and writing. 42
• Speaks Demon God Tongue fluently, surprising Rujierd and allowing him to converse with Roxy’s parents. 224 227
• Encourages Migurdia villagers to learn Demon God Tongue rather than relying entirely on telepathy, linking language education to contact with other races. 230 465
• Trains Sylphy with magic as her primary discipline and swordsmanship as a supplement, including basic Water God Style defensive techniques. 145 155 160
• Teaches Bannie Human Common Tongue and guides Aisha through precise mana-control exercises. 387 487
• Prepares fusion dishes with supplies from Zant Port, using cooking to strengthen his relationship with his Beastfolk hosts. 280

Leadership and Planning

Cui applies original-story knowledge, political relationships, and practical judgment to rescue and reconstruction.

• Designs the Great Migration response to the Displacement Incident, using his reputation as a prophetic figure to support evacuation decisions and reassure frightened residents. 188 199
• Takes part in reorganizing the Relief Corps and assumes responsibility for the reconstruction of the Fitoia Territory. 387 399
• Uses rank, law, and clear explanation to defuse a guild confrontation over a misunderstood search-and-rescue commission without fighting. 298
• Protects companions through strategic use of reputation, including impersonating the North God to secure passage for Rujierd. 266
• Recruits for character as well as competence and promises Counter Arrow a future as honored Boreas retainers when they are ready. 399

Equipment

• Steel longsword — Given by Carl when Cui leaves Turan for Roa. 22
• White horse — Also gifted by Carl for his journey to Roa. 22
• Mother’s diamond ring — Worn on his left pinky after transmigration. 3
• Cracked jade pendant — A childhood keepsake with a protective pattern. 3
• Keychain tools — Includes a nail clipper, miniature butterfly knife, and metal bottle opener; the bottle opener is used to start his first fire. 3
• Roxy’s amulet — Recognized by her parents during his stay in Migurdia and becomes part of their questioning about his relationship with her. 224
• Rowin’s scimitar — Given with money, a rough map, and food when Cui’s group leaves Migurdia Village. 230
• Clairvoyance Demon Eye — Integrated into his abilities; requires supplied magic power to activate. 266
• Begaritt magic sword — An unusual sword that becomes stronger against stronger targets: it cannot cut tofu or ordinary skin, but slices hard steel and becomes exceptionally sharp against God-level opponents. Cui uses it during the renewed confrontation with Orsted. 581
• Enchanted dagger — A valuable belated wedding gift from Zoldat. 500
• Mana crystals — External power sources for experiments and prepared magic; their compatibility requires careful management of his Anti-Magic Field. 96 540
• Light Spirit scroll — Briefly summons a small spirit for illumination and scouting when linked to a mana crystal. 540
• Household teleportation circle — Installed in his courtyard, permitting distant relatives such as Roxy’s parents to visit. 487

Story Role

Arrival and Survival

After reincarnating into the Six-Faced World, Cui survives alone in the wilderness, kills an Assault Hound pack, and realizes that his body and perception have changed beyond human limits. His first contact with Carl’s caravan is strained by his inability to speak Human Common Tongue and the group’s fear of his strange appearance. 3 4 5 6

The Red Beard Caravan

Cui aids Carl’s caravan after his Anti-Magic Field prevents Battle Aura from affecting him. During the Grey Wolf Bandits’ ambush, he chooses to intervene rather than flee, saves Dak, kills his first human opponents, and reveals the full danger of his nullification ability. 6 9

The surviving caravan accepts him with gratitude. Carl and Dak teach him Human Common Tongue and local swordsmanship, while Cui gains his first meaningful support system in the new world. He later refuses Carl’s invitation to join the Red Beard Adventurer Party, choosing instead to follow his own plans. 10 13 19

Journey to Roa and Ghislaine’s Rescue

Cui leaves Turan for Roa with supplies, a horse, and a steel sword from Carl. On the road, he finds Ghislaine Dedoldia starving and near death. His careful treatment restores her will to live, and she swears to serve as his sword in repayment. 22 23 24

Boreas Tutor

Seeking access to books and information, Cui applies for the Boreas family’s tutor position. Sauros hires him alongside Ghislaine after witnessing Cui endure a strength test without moving. 21 27

At House Boreas, Cui teaches arithmetic, reading, and writing while Ghislaine teaches swordsmanship. His early relationship with the Boreas young lady is hostile and marked by repeated ambushes, skipped lessons, and destructive behavior; he gradually earns cooperation by adapting instruction to her love of combat. 31 32 42

His pupil, subsequently called Alice Boreas Greyrat, becomes increasingly attached to him as their lessons improve. He recognizes her exceptional perseverance and swordsmanship potential, while later visits demonstrate real progress in her reading despite her insistence that she is not trying hard. 30 142 155

Sword King Breakthrough

Cui’s research and training reveal the limitations of his aura-less combat style. After witnessing Ghislaine’s Sword King strike, he experiments with using Mental Power as an alternative energy source. His success earns Ghislaine’s recognition as a Sword King, though the technique nearly empties his Mental Power and leaves him vulnerable afterward. 46 47 48

Encounter with Roxy

Cui meets Roxy Migurdia when she arrives to apply as a magic tutor. Recognizing her from his former life’s knowledge of Jobless Reincarnation, he is shaken when Philip rejects her application and impulsively stops her from leaving. 50

Their relationship develops into sustained magical collaboration. Cui helps Roxy learn silent casting through magic models and mental calibration, then creates Blue Stream Blade using externally supplied mana. She later becomes his girlfriend and a central source of emotional support. 95 96 176

Philip’s Marriage Proposal

Philip offers Cui a marriage alliance with Alice to secure his support in the struggle for leadership of House Boreas. Cui refuses both the proposed marriage and becoming Philip’s retainer on those terms, insisting that Alice’s future should not be arranged as a political transaction. Nevertheless, he promises to help Philip protect any future children and, if possible, recover his two sons from the royal capital. His stated reason is Alice’s own wish to protect her father. 83

Buena Village and Chosen Responsibilities

Cui becomes Buena Village’s Auxiliary Defense Knight and establishes a routine of travelling between the village and Roa. He works alongside Paul, studies magic with Roxy, continues training with Ghislaine, and teaches Sylphy after defending her from bullying and prejudice. 126 142 145 155

Following the household crisis involving Lilia, he promises to keep employing her and help raise her unborn daughter, Aisha. His own painful childhood reinforces his determination not to abandon vulnerable people or repeat his father’s failures. 151

Preparing for the Displacement Incident

Cui studies teleportation circles and the anticipated Displacement Incident in an effort to protect the Fitoia Territory. With Roxy and Ghislaine’s support, he brings urgent information to the Boreas leadership, works on migration routes, and becomes the public face of a prophetic warning. 155 176 179 188 199

The Human God intervenes through dream encounters, reveals knowledge of Cui’s original-world story, and warns that his actions may have advanced the disaster’s timing. Cui remains unsure whether these warnings are sincere or manipulative. His Great Migration plan nevertheless becomes a major part of his reputation as the hero of Fitoia. 182 199 308 379

First Battle with Orsted

When Orsted attacks Roxy and Ghislaine, Cui combines Magic Nullification with Beyond the Sword of Light and severs the Dragon God’s left arm. Orsted heals the injury and decides that Cui, whom he considers a potential Human God’s Apostle, must be killed. His serious counterattack overwhelms the exhausted Cui and leaves him gravely injured. 210

The Displacement Incident interrupts the encounter, and Cui later owes his survival to Rujierd’s rescue. During his subsequent fever, Alice and Sylphy remain beside him while he calls for his mother in Chinese. 219 224 557

Migurdia Refuge and the Saviors

Cui awakens in Rowin’s home in Migurdia, thanks Rujierd, and tells Roxy’s parents that she is alive. He openly admits that he and Roxy are seriously dating and hope to marry, provoking Rowin’s protective anger and Rokari’s delight. 224

During his stay, Cui uses nullification to treat magic-stagnant farmland and encourages practical magic and Demon God Tongue education. He leaves with Alice, Sylphy, and Rujierd to search for Roxy and the others, receiving supplies and Rowin’s scimitar. He subsequently registers as captain of the Saviors party, initially receiving the guild’s F rank despite his considerable fighting strength. 230 242 465

Great Forest Rescue

In the Great Forest, Cui develops Mental Shock and Telekinesis while confronting Giles, a North Saint responsible for arson and abductions. His mental disruption allows Alice and Rujierd to free a Fox-Eared Girl, and his telekinetic attack helps subdue Giles without sacrificing the hostage. 278

The rainy season delays the Saviors’ journey. Cui practices his new mental abilities, teaches his companions, cooks for the Beastfolk, and grows close to the rescued children, particularly Luna Kitsune. Rujierd assists local warriors in eliminating the remaining smuggling forces. 280 289

Benedictine and the Shirone Trap

After the Human God probes his distress over a dream of an imprisoned blue-haired girl, Cui learns her identity as Benedictine Kingdragon. He later uses the royal request won by Alice at the Dragon King Martial Arts Tournament to bring the sheltered princess with the party. His desire to help her and alter the future leads to jealousy and misunderstandings with Alice and Sylphy. 339 340 351

In Shirone, Cui helps suppress the abnormal powers affecting Zanoba and Pax. Pax’s gratitude turns into fear of losing his restored appearance, and he traps Cui in an Emperor-level barrier to monopolize his Magic Nullification. Cui remains calm, studies the circle, survives the fall through mental control, and challenges Pax’s assumption that his power is limited to Sword King level. The resulting royal settlement sends the princes abroad as nominal students and actual hostages while preserving their lives. 355 357 358 359 360

Reunion and Reconstruction

After investigating what he believes is a trafficking warehouse, Cui discovers that its residents belong to a rescue group formed to search for him, Alice, and others lost in the displacement. Carl identifies him, resolves the misunderstanding, and warmly reunites with him ten years after their first encounter. The group has grown to nearly a thousand members and also opposes trafficking in the unsettled territory. 377 379

Back among the Greyrats, Cui helps reorganize the Relief Corps, supports reconstruction, and teaches Bannie Human Common Tongue. His honorary dukedom is tied to his engagement to Alice and the kingdom’s wish to bind him to House Boreas and the royal family. As prospective head of the Boreas branch, he begins recruiting trustworthy future retainers, including an open invitation to Counter Arrow. 387 399

Begaritt and North God III

While travelling with Roxy and Elinalise toward an ancient teleportation ruin, Cui encounters Alexander Kalman Reibak, North God III, wielding the Dragon King Sword. Alexander knows that Cui previously used his name but recognizes him as a genuine champion. 449 450

Cui discovers that his passive field cannot fully defeat the sword’s gravity magic. Maximum output nullifies the effect and disconnects the weapon from its wielder, allowing Cui’s speed and precision to overwhelm Alexander. A violent sandstorm prevents Cui from securing the sword and carries Alexander and the weapon away. The victory is later reflected in the Seven Great Powers monument, which replaces the North God’s seventh-place name with “Nullifier.” 451 493

Marriage and Life in Sharia

Upon returning, Cui declares that he intends to marry Roxy, then admits that he loves Alice and Sylphy as well and proposes marriage to both. The announcement creates hurt and jealousy, particularly over the position of principal wife. He and Roxy seek a permanent home in Sharia, and his commitment to future parenthood reflects a wish to remain present for his children rather than leave them behind for adventure. 456 457 458

Roxy, Alice, and Sylphy subsequently become his three wives. Their shared household includes Lilia, Aisha, and Bannie, and later takes in Julie. Rowin eventually entrusts Roxy to Cui sincerely, while the household teleportation circle allows distant family visits. Domestic affection remains mixed with comic rivalries, including a prolonged cold shoulder after Cui upsets all three wives. 472 475 487 505

Ranoa University and Public Recognition

Cui participates in university life, studies advanced magic, and collaborates with Nanahoshi’s summoning experiments. Linia and Pursena attempt to evade unwanted Beastfolk suitors by publicly claiming to be his future fourth and fifth wives, redirecting courtship challenges toward him. Their statement is a protective scheme rather than an established marriage. 484 487 506 508

Badigadi’s visit reveals Cui’s place among the Seven Great Powers. Following their confrontation, Badigadi and Cui receive largely symbolic martial-arts advisory posts from the Three Great Principalities. Cui’s reputation protects the Beastfolk princesses from further harassment, while his personal connections help the university Alliance attract prominent members. 492 493 505

Parallel-World Knowledge and the Human God

During a later trip to the Demon Continent, Cui uses the Adventurers’ Guild to search for Kishirika and discovers an old commission still seeking him after the displacement. He takes steps to cancel it, confronting the long-lasting consequences of his absence. 540 541

A subsequent encounter with a modern-clothed parallel version of himself culminates in the awakening of his Parallel World Ability. After sorting the incoming memories, Cui identifies the Human God as the hidden manipulator behind the major events described in the fuller original novel. He plans to reach the Void Space and confront him before Dragon King Calendar year 530. 554 555 556 557

Despite his resentment toward Orsted, Cui concludes that the Dragon God is a necessary ally against their common enemy. He also suspects that a child of his own union with Roxy might inherit the role of the future savior, though this remains his inference rather than an established outcome. He decides to tell his wives about the future information and original story rather than carrying the burden alone. 557 560

Sword Sanctum Challenge and Preparation

A sparring defeat against Alice and Ghislaine together exposes the limits of Cui’s field and superior reflexes. Seeking techniques beyond Sword King level, he travels with them to the Sword Sanctum. Once there, he rejects the assumption that he has come as a conventional student and declares that he wants to test his sword against Gal Farion. 565 566 573

After Cui criticizes the Sword God Style’s directness and fixation on speed, Gal orders Sword Emperors Timothy Breeze and Raida to attack him together. Cui nullifies their Battle Aura, catches Raida’s sword, and breaks both weapons with one focused strike. His identity as the Nullifier is then revealed to the assembled swordsmen. 574 575 576

Cui redirects Gal’s God’s One Slash and contests his repeated Sword of Light attacks in an outdoor duel. The exchange ends after thirty-seven clashes, leaving Gal with a shallow chest wound and Cui with a shredded cuff. Cui then remains at the Sanctum for the preparation period, sparring daily with the Sword Emperors, refining precise nullification, and learning King- and Emperor-rank Sword God Style techniques. 577 578 579

Renewed Confrontation with the Dragon God

Cui later joins Gal Farion, Alice, Ghislaine, and Rujierd against Orsted. The Dragon God initially evades the coordinated assault of three Emperor-level fighters and one God-level fighter without injury, demonstrating the gap the group must overcome. Cui positions himself behind the formation with his Begaritt magic sword and prepares maximum nullification. 581

When Orsted moves to recover a severed hand, Cui and the remaining attackers press the opening rather than allow him to reattach it. Cui expends all his Mental Power to cancel the Dragon God’s magic power and support the coordinated effort. 582

Relationships

• Carl — Caravan captain who initially tests and fears Cui’s abilities; later becomes a trusted benefactor, language teacher, and source of practical support. Carl subsequently helps found the rescue group searching for Cui and warmly identifies him during their reunion ten years after their first meeting. 6 10 22 379
• Dak — Carl’s child and Cui’s admirer. Dak teaches him Human Common Tongue and North God Style fundamentals, while Cui serves as Dak’s model of heroism. Before leaving Turan, Cui encourages him to become a hero through meaningful deeds rather than fame alone. 11 17 19 22
• Ghislaine Dedoldia — Cui saves the starving Sword King, and she swears to become his sword. She becomes his travelling companion and Sword God Style instructor. Her loyalty remains a source of reassurance; she accompanies him to the Sword Sanctum, tests his limitations alongside Alice, and participates in the later confrontation with Orsted. 23 24 37 48 176 565 581
• The Boreas young lady / Alice Boreas Greyrat — Cui’s difficult academic pupil; their relationship begins with hostility and repeated attacks but develops into a more effective teacher-student bond as he bases lessons on her interest in swordsmanship.

Trivia

• Cui’s attempt to communicate by carving Chinese characters into stone confirms that no one in the caravan recognizes his writing system, intensifying his sense of isolation. 7
• He recognizes the Six-Faced World as the setting of Jobless Reincarnation only after hearing place names, observing its monsters and sword styles, and seeing Chaos Breaker above Turan. 15
• Cui identifies himself to Sauros as a Sword Saint before his later Sword King breakthrough. 27 48
• His Adventurers’ Guild registration begins at F rank despite his Sword King-level power. His registered age of 19 attracts more of his attention than the low adventurer rank. 242
• His declaration that he is “Alexander Kalman Rekubei” at Wen Harbor is an impersonation used to help Rujierd, not an actual North God title. Alexander later acknowledges that Cui used his name. 266 450
• Because he has neither measurable mana nor Battle Aura, the Dragon-Eye Stone treats him as an ordinary person and prevents him from entering even the Beginner Group of the Dragon King Martial Arts Tournament. 334
• “Prophetic Blessed Child” is his public reputation as a disaster-foretelling hero; his anomalous Mental Power is not thereby established as a conventional Blessed Child ability. 199 379 407
• He references Earth fiction when interpreting his experiences, including Kamen Rider, Naruto’s long-standing genin rank, and Byakuran Gesso’s Parallel World Ability. 516 556 566
• He is described as the only person outside the usual eight contenders to enter the Seven Great Powers rankings in a hundred years. 576
• Learning King- and Emperor-rank techniques and contesting Gal Farion do not come with an explicitly stated promotion to Sword Emperor or Sword God. His established monument title remains “Nullifier,” the seventh seat of the Seven Great Powers. 565 576 579
