Baek Haeju

Baek Haeju is the manufactured Paradise identity of Yoo Seonhwa, Seol Jihu's childhood friend and former partner. In Paradise she becomes the first Earthling to reach Level 8, the spear master known as the Sacred Empress, and one of humanity's most experienced fighters against the Parasites. Her secrecy lets her protect her family on Earth and operate outside the organizations that dominate other Earthlings, but it also forces her to care for Seol from a distance. Much of her development concerns the boundary between protection and control: she begins by hiding her identity, arranging guardianship through Seo Yuhui, and trying to remove Seol from danger, then gradually accepts his choices, fights beside him, and finally tells him the truth.

Biography

The childhood bond damaged by gambling

Yoo Seonhwa and Seol grow up as members of two closely connected families. After the death of Seonhwa and her sister's parents, the young Seol takes an unusually active role in caring for the sisters and persuading his own siblings not to make them feel like outsiders. His kindness binds the households together and becomes the emotional basis of Seonhwa's loyalty to him. Their relationship develops from childhood companionship into romance and cohabitation; her habits of feeding him well, imposing a regular sleep schedule, and correcting his impatience remain embedded in his behavior long after they separate. (Chapters 80, 93, and 98)

That domestic partnership collapses under Seol's gambling addiction. He lies, borrows or takes money, repeatedly promises to change, and wounds Seonhwa deeply enough that she considers ending both the relationship and her own life. Even after breaking up with him, she cannot treat him as a stranger. When he comes to her cafe for money, she has two million won prepared because she expects another desperate request; after confirming that he has voluntarily banned himself from the casino, she believes him once more but admits that she is too exhausted to forgive him. His repayment of the money he owes does not erase the injury, but it gives her the first evidence that his conduct may be changing. (Chapters 2, 20, and 193)

Seonhwa's guardedness is therefore not indifference. Her later explanation establishes that she had remained faithful while overseas, kept Seol's photographs as her principal comfort, and repeatedly accepted him again after previous apologies. This history makes another disappointment feel intolerable. When she subsequently tests whether he has truly changed, she is protecting herself from a familiar cycle rather than demanding a performance of repentance. The same history also explains why she continues helping his family and defending space for his reconciliation even when she has not yet decided whether she can trust him personally. (Chapters 99, 156–159, and 193)

A manufactured legend in Paradise

Seonhwa first enters Paradise in March 2013 while supposedly studying overseas. Her initial goal is practical rather than martial: Paradise contains plants and seeds unavailable on Earth, and its different flow of time appears useful for research. The organization that invited her is destroyed during an expedition, leaving her exposed to its enemies. In the Dragon's Nest she finds an appearance-changing artifact, an ancient weapon, wealth, and growth potions. She uses the disguise artifact, Seo Yuhui's assistance, and the poor records of Paradise's chaotic early period to make Yoo Seonhwa appear dead and construct “Baek Haeju” as an older, untraceable Earthling. The exact name and operating limits of the disguise artifact are not given. (Chapters 185 and 193)

The false history protects both her Earth identity and her freedom in Paradise. Organizations that demand access to a Status Window are effectively closed to her, so she works alone and uses the Dragon's Nest gains to advance without institutional sponsorship. Her forged seniority is convincing because very few Earthlings from the earliest Neutral Zones survive to contradict it. A surviving record of the third Banquet states that she killed all but one escapee in Stage 3 and declared the stage a battle royale, although the record does not establish her private reasoning. At Level 5, Ira later permits her to enter the Path of the Soul, where she passes two trials designed to make cooperation necessary because of her insistence on doing everything alone. The resulting Divine Vestige helps establish the Sacred Empress as the first Earthling to reach Level 8 without another person's help, but does not make her an Executor. (Chapters 61, 71, 94, 101, 162, and 185)

Her early career also connects her to the generation that first challenged the Parasite Queen directly. Baek, Seo Yuhui, Sung Shihyun, and other top Earthlings join the first Imperial Oath expedition. When the activated oath fails to expel the Queen completely, Baek, Seo, and Sung each take one of the three stele fragments so that the Queen cannot recover all of them at once. That shared responsibility outlasts the team's collapse. Baek and Sung have a major personal fight and separate, while her alliance with Seo survives because it is founded on reciprocal knowledge, shared danger, and the secret of Baek's identity. (Chapters 101 and 178)

Seonhwa originally intends to gather enough materials and retire in 2015, but Seol's worsening addiction changes her timetable. She returns to Korea and leaves Paradise in 2014 so that she can care for him, using money she has slowly converted from Paradise to fund the millions he repeatedly demands. After roughly ten months on Earth, despair drives her back. Paradise is both an escape from the relationship's pressure and a place where she hopes to find something capable of restoring the person Seol once was. Her reputation as a detached lone fighter thus coexists with a private career repeatedly reorganized around his survival. (Chapters 185 and 193)

Protection behind the mask

When Seol visits her cafe after obtaining his invitation, Seonhwa sees the golden stamp on his hand. Approaching him openly would connect Baek Haeju to Yoo Seonhwa and expose both families to Paradise's conflicts, so she urgently asks Seo Yuhui to watch over him instead. She attempts to pull him out after his first war, but he refuses. From then on, she balances two conflicting aims: preserve the identity that makes protection possible, and intervene whenever his choices threaten to destroy him. This explains why “Baek Haeju” appears selectively around crises despite her reputation for refusing attachments. (Chapters 20, 185, and 193)

The Arden Valley war turns that concealed concern into direct action. Baek enters the fiercest part of the battle by ambushing Undying Diligence, then endures the Army Commander's attempt to exhaust her with disposable Nosferatus. When Seol creates an opening, she recognizes it immediately, drives her spear through the Commander's heart, and floods his body with holy water. Her energy combines with Seol's lightning-based anti-evil power, allowing them to overcome the Commander's resistance. Their coordination is improvised rather than planned, but it demonstrates the compatibility between her disciplined spear work and his explosive attacks. (Chapters 90–92)

After Seol's body collapses, Baek's priorities become unmistakable. She first tries to stop Seo from paying an extreme price to preserve him, then helps hold him alive until the Federation's Elixeer arrives. Placing a hand against his back, she calms the mana destroying his circuit, contributes her own life force, and prepares his body to receive the medicine. This intervention does not heal him by itself; Seo's Ceremony, Jang Maldong's acupuncture, and the Federation's Elixeer are all necessary. Baek's role is the bridge between otherwise incompatible treatments, and the effort leaves her exhausted after an already prolonged battle. (Chapters 93–95 and 185)

Baek initially intends to decide Seol's future for him. If he remains comatose too long, she will have him killed so that he can revive on Earth; if he wakes, she still wants to send him back because his fame has attracted the Parasite Queen. Seo rejects Baek's assumption that concern gives her sole authority, and their argument begins a lasting rivalry over how Seol should be protected. The conflict identifies Baek's central flaw: she correctly recognizes danger, but can treat the person endangered as something to be managed rather than someone entitled to choose. (Chapters 94–95 and 185)

The Spirit Realm and a visible alliance

Seol later asks Seo to recruit Baek for the Spirit Realm expedition because he remembers her as the spear user who saved him in the valley. Baek agrees that restoring the Spirit Realm is strategically necessary, but refuses to offer unconditional obedience. She demands authority to order a retreat if a majority supports her judgment and promises to knock Seol unconscious and carry him home if necessary. The condition combines professional caution with private fear: she has more experience against the Parasites than anyone present, yet her concern is specifically that the whole group—and Seol in particular—survive a mission whose moral appeal could obscure its risks. (Chapters 141–142)

Against Raging Temperance, Baek converts that authority into a working battle plan. She rebukes Seol for rushing an unknown enemy, uses Mental Transmission so the Commander cannot overhear their tactics, identifies the enemy's curse and barrier, and creates an opening for the Spear of Purity. Her own Tathagata Spear follows through the narrow breach, after which her holy water again combines with Seol's lightning. She also explains the limit on an Army Commander's released divinity: the explosive state lasts only about ten to thirty minutes and is followed by collapse, so surviving rather than contesting it directly can create the real opportunity to kill. Her judgment turns an initially disastrous charge into a coordinated victory. (Chapters 145–146)

The appearance of Twisted Kindness exposes the limit of Baek's strength. Baek can contest the Commander more effectively than any other expedition member, predict movement from a spear throw, and use the battlefield's wire network as footing, but she cannot overcome a fully absorbed divine power. She forces her own green energy to rampage to keep fighting, risking her life and becoming nauseated under the strain. Even then, Twisted Kindness can immobilize, disarm, and nearly kill her. Baek's performance is consequential because it creates openings for the group; it is not evidence that she is individually equal to the Commander. (Chapters 146–148)

At Tigol Fortress she continues acting as both fighter and safeguard. She warns the group away from attacks that cannot be blocked, drags Seol clear of a silent cutting strike, helps oppose Vulgar Chastity, and fights Sung after his defection becomes public. Her rage at Sung is personal as well as strategic—she had wanted to kill him before he joined the Parasites—but she suppresses it long enough to coordinate through Mental Transmission rather than accept his provocation. The campaign ends with the Federation restored to the human alliance, but also with Baek newly visible as one of Seol's closest battlefield partners. (Chapters 149–152)

The Path of the Soul and learning to help without deciding

After the war, Baek carries Seo's secret message to Seol and protects the deception meant to expose internal traitors. The small assignment illustrates why Seo trusts her: Baek delivers the note by Mental Transmission, confirms only what she personally knows, and has Seol burn it. Outside formal danger, her reserve begins to crack. She makes an awkward joke about a love confession and silently joins Seol's late-night ramen when hunger defeats her aloof pose. These moments do not erase her secrecy, but show that the Sacred Empress persona is a controlled presentation rather than her entire temperament. (Chapter 153)

When Kim Hannah tells her that Seol has entered the Path of the Soul for three trials, Baek enters the space herself. She is alarmed by the enlarged mountain and the danger of ten-times-accelerated isolation, reprimands him for ignoring Gula's warning, and tries to demonstrate a route through the ordeals. Her experience is relevant but not transferable: the Path shapes its trials around the entrant's desires, and Seol's trials require him to succeed alone, whereas hers had required cooperation. Black Seol Jihu therefore stops her intervention and defeats her decisively. The encounter teaches Baek that even expert help can become obstruction when it denies the condition another person has chosen to face. (Chapters 161–162)

She nevertheless continues visiting within the allowed boundary. Baek brings food, observes Seol's training, and provides company without completing his trials for him. Her earlier warning—that injury makes achievement meaningless—does not change, but her method does. She moves from trying to push his boulder herself to supporting the conditions under which he can push it. His training also uses her sword-qi control as a technical reference, connecting her guardianship to his martial development without making her the sole author of it. (Chapters 162–166)

Baek also lends her reputation to humanity's internal reform. Her presence at the public screening that exposes Earthling corruption prevents hostile organizations from suppressing it, even without a fight. This is an unusually institutional use of a career built in isolation: the woman who avoided every organization makes her name serve as deterrence while Valhalla changes the political environment around her. The choice brings her closer to Seol's coalition without requiring her to surrender the private identity on which her Earth family's safety still depends. (Chapters 168 and 172)

The Imperial Oath and the cost of obeying Seol

The second Imperial Oath crisis reopens obligations from Baek's first generation. After the hidden stele is endangered, she joins the expedition into the Empire and accepts custody of the recovered oath in her Dimensional Pocket. Seol separates the team into groups and asks Baek, Kazuki Ayase, and Maria to escape with it. When the Parasites ignore her party, Baek correctly senses that the real target may be Seol and wants to return. Kazuki points out that only she can conceal and carry the stele; turning back would endanger every group and the object Seol remained behind to protect. (Chapters 178–183)

Baek ultimately continues forward. The choice is not emotional abandonment but obedience to the responsibility Seol entrusted to her. It marks the inverse of her earlier conduct: she does not knock him out, override his plan, or substitute her judgment once the cost becomes personal. That restraint preserves the oath and helps twenty members escape, but it also leaves Seol alone against the Parasite armies. When Teresa's life contract burns, Baek races back while still hoping to disprove his death, only to be too late to change it. The consequence makes her new respect for his choice painful rather than triumphant. (Chapters 183 and 187–188)

During Seol's death penalty on Earth, Seonhwa becomes one of his principal guardians. He has lost his Paradise memories and falls into violent confusion, self-harm, and suicidal behavior; she arranges treatment, coordinates with his family, and initially keeps Paradise visitors away in the hope that forgetting will let him begin again. When isolation fails, she changes course and permits carefully managed contact. She also leaves a message in the record prepared to restore him, promising to look after his family. Her response again moves between protection and restriction, but now she revises her decision when evidence shows that control is worsening the person she wants to save. (Chapters 188–190)

The name behind the Sacred Empress

After Seol revives, Baek visits him at dawn and cautiously tests what he remembers. He already knows her identity through Seo's revealed past, but waits for Seonhwa to speak in her own time. She prepares his return to his family, gives them an explanation they can trust, and then tells him the truth in private. “Baek Haeju,” she explains, is a manufactured character: she entered later than Seo, used the Dragon's Nest disguise to erase her trail, and built an impossible early history so investigators would search the wrong records. (Chapters 192–193)

The confession also resolves the motive behind her interventions. She returned to Paradise partly to search for a way to restore Seol, recognized his stamp at the cafe, asked Seo to protect him, tried to withdraw him after the first war, and watched his later development from behind the false face. She delayed the revelation because his past apologies had repeatedly ended in betrayal. What finally convinces her is his conduct after losing his memories: even without Paradise's rewards or the identity he had built there, he refuses to gamble. For Seonhwa, that choice proves the change belongs to him rather than to circumstance. (Chapter 193)

Revealing herself does not mean publishing the secret. They agree that she will remain Baek Haeju in Paradise because there is no immediate reason to expose Yoo Seonhwa or their families. The change is relational: Seol can now understand her concern, Baek can speak about strategy without pretending detachment, and both can discuss a future without treating the past as erased. Their reconciliation is not instant absolution. It is Seonhwa's decision that she has enough evidence to risk trust again. (Chapter 193)

Sacred Spear and the final war

Before the final invasion, Seol spends captured divinities through Gula to promote his companions. Baek advances permanently from Level 8 Sacred Empress to Level 9 Sacred Spear. The promotion gives her access to reinforced sword qi, the condensed cutting force previously beyond her learned skill, and places her among Valhalla's new Unique Rankers. Training in the Path of the Soul prepares the group for the leap, but the text attributes the actual class promotion to Seol's wish and the offered divinities rather than to ordinary accumulation. (Chapter 194)

In the campaign against the Parasite Empire, Baek's main responsibility is containing Twisted Kindness so that Seol can advance. Even with a dislocated or broken arm and depleted mana, her reinforced sword qi repeatedly blocks the Commander from reaching the support line. World Tree energy restores her injuries and mana, allowing her to coordinate with the phoenix, Apostles, and other attackers. The battle remains collective: Baek reads the decisive opening and thrusts at Twisted Kindness's heart, but the Commander deliberately turns the exchange into a mutual kill, and only Seo's barrier prevents the counterstroke from taking Baek's life. The Tathagata Spear's penetration becomes fatal because of the damage accumulated by the entire allied force. (Chapters 197 and 199–200)

Baek then joins the final assault on the Parasite Queen. She can follow the goddess's movements only half a beat late, and a direct attack throws her down, establishing the remaining difference in scale. Even so, she retrieves her spear, cuts at the Queen's side, and later spends her reinforced sword qi to reduce the final distance Seol must cross. She disappears from the advance after buying those steps, while successive allies continue the relay. Her contribution is therefore neither a private duel nor a ceremonial presence: she removes the strongest remaining Commander and spends the strength of her new class creating Seol's route to the Queen. (Chapter 200)

A life shared between two worlds

After the war, Baek works beside Seol and Seo in his Paradise ramen restaurant. The work turns small wartime intimacies—shared food, quiet company, and the promise of an ordinary future—into daily life. She remains a Level 9 combatant and later joins the expedition against the otherworldly god occupying the old palace, where her white robe is stained with alien blood. Peace therefore changes what she fights for without reducing her to retirement. (Chapters 204–205 and 249–252)

Her relationship with Seol remains complicated by the damage of their first romance and by his other relationships. In the final period, Seonhwa initially accepts a return to childhood friendship and focuses on expanding her cafe business, including plans for overseas growth. She then enters the larger Paradise household, insists that any Earth wedding with Seol will be hers, and eventually marries him in Paradise. The epilogue confirms that they have a child together. When Seol finally tells his parents the truth about Paradise and his family there, Seonhwa appears openly as both Baek Haeju and Yoo Seonhwa rather than maintaining a division between the two lives. (Chapter 253)

Appearance and personality

Baek's Paradise appearance is itself an artifact-assisted disguise. In that form she is a young woman with long hair, fair skin, cold and tranquil eyes, and an almost mystical bearing. She usually wears a long white traditional or ceremonial robe and carries an apple-green spear. The calm clothes and controlled expression reinforce the public image of the Sacred Empress, but neither her face nor the name Baek Haeju belongs to her Earth identity. The exact transformation rules and the degree to which the artifact changes her body, rather than only her visible features, are not established. (Chapters 90, 142, 162, 185, and 200)

As Yoo Seonhwa, she is a notably beautiful Korean woman with long, flowing hair and clear eyes. Her Earth presentation is tidy and practical, suited to managing a cafe rather than advertising a martial identity. The two forms retain a similar emotional presence, which is why Seol sometimes senses familiarity without identifying her. The narrative does not provide a complete Status Window or reliable measurements for either appearance. (Chapters 20, 34, 52, and 99)

Baek's public personality is restrained, solitary, and exacting. She speaks little, resists provocation, and makes only the movements needed in battle. “Live alone, die alone” is attributed to her as a motto, and her false identity requires the habits behind it: no organization, little unnecessary disclosure, and no visible attachment an enemy can trace to Earth. This composure makes her an exceptional battlefield analyst, but can also make a decision she has already reached sound like an order that others have no right to question. (Chapters 91, 142, 153, and 185)

Seonhwa's private temperament is warmer and more volatile. She likes food, is drawn to cute animals, makes dry jokes, sings when playful, and can become openly jealous or possessive around Seol. She is also highly observant: she recognizes his lies by the way he avoids her eyes, tests claims before accepting them, and notices the practical dangers created by linking Earth and Paradise identities. Her coldness toward Seol during his addiction is the exhausted defense of someone who has forgiven too often, while her severity in Paradise frequently conceals fear for his life. (Chapters 20, 99, 143, 151–153, and 193)

Her recurring weakness is protective control. Baek tries to decide whether Seol should remain in Paradise, claims authority to force him out of an expedition, and attempts to complete part of his Path of the Soul herself. Each choice has rational grounds, but each risks replacing his agency with her judgment. Her development does not make her less cautious. Instead, she learns to support a choice she would not make, as when she carries the stele away rather than return to Seol, and to reveal the vulnerability behind her caution, as when she finally explains why another betrayal frightened her. (Chapters 94–95, 142, 162, 183, and 193)

Abilities and class

Divine Vestige and class progression

Baek receives entry to the Path of the Soul at Level 5 at Ira's discretion. She completes two personalized trials and acquires the Divine Vestige, leaving a faint blue scar above her navel and granting the qualification to re-enter the Path. This is distinct from being Ira's Executor: the text explicitly states that she is not an Executor. The trial's demonstrated function is developmental rather than a named combat technique, and its exact rewards beyond the Vestige and her later advancement are not enumerated. (Chapter 162)

She is the first Earthling confirmed to reach Level 8, advancing independently to Sacred Empress. That rank makes her the strongest active Earthling for a substantial period, but it does not eliminate ordinary limits. Prolonged combat tires her; forcing her energy to rampage causes physical distress; fully empowered Army Commanders can overpower her; and Black Seol Jihu defeats her after identifying a weakness in her technique. Her status is exceptional within humanity, not absolute across Paradise's divine hierarchy. (Chapters 91, 101, 146, and 162)

Seol's prewar wish promotes her to Level 9 Sacred Spear. This is her latest confirmed permanent class. Reinforced sword qi appears in her arsenal after that promotion, allowing her to pressure Twisted Kindness and injure even targets resistant to ordinary sword qi. The technique remains costly enough that she must choose openings carefully, and the Parasite Queen still exceeds her perception and reaction speed. (Chapters 194 and 197–200)

Jade Spear Technique and combat method

The Jade Spear Technique is Baek's signature learned martial art. It supports thrusts, throws, sweeps, and the release of jade-colored sword qi through a spear. She can split that energy into dozens of projectiles, launch it upward and bend the trajectories so they rain onto separate targets, or condense a large volume into a coordinated hail. This precision lets her attack from angles that evade interception and control a wide area without abandoning the spear's direct reach. The source does not provide a complete list of named forms. (Chapters 113, 162–163)

Her greatest advantage is judgment rather than raw output. Baek calculates a moving target's response in a fraction of a second, predicts where a thrown spear will force an enemy, and launches her own weapon into the resulting path. She also reads enemy resource use, recognizes when a released divinity is temporary, and distinguishes an attack that can be blocked from one that must be evaded. These are demonstrated products of experience and training, not a stated precognitive ability. A wrong premise can still defeat her calculations, as Twisted Kindness proves by deliberately baiting her final thrust. (Chapters 145–148, 152, and 200)

The technique can be countered. Black Seol Jihu knows an unspecified weakness in the Jade Spear Technique, closes inside her guard, and disarms her. His reinforced sword qi then shreds her conventional sword-qi barrage. The scene establishes both a technical vulnerability and a power threshold: precise control does not compensate when an opponent understands the form and possesses vastly greater energy. The exact weakness is never explained, so it cannot be generalized to every opponent. (Chapter 162)

Holy water, energy control, and support

Baek can generate holy water described as an apex anti-evil energy. She channels it through her spear into a target, where it combines especially well with Seol's lightning-based anti-evil energy. Against Undying Diligence and Raging Temperance, the interaction attacks from inside the body and helps overcome the Commanders' regenerative or defensive power. The text demonstrates this effect against evil or Parasite targets; it does not establish holy water as a universal damage amplifier. (Chapters 91 and 145)

Her control also has a medical application. After Arden, she uses touch to calm the mana rampaging through Seol's damaged circuit, supplies life force, and makes his body capable of surviving until an Elixeer can be administered. This is stabilization, not complete healing or resurrection. It requires her to remain exposed and protected while working, and it operates as one component of a treatment that also needs a Priest's Ceremony, acupuncture, and the Elixeer. No formal skill name is supplied. (Chapters 94 and 185)

Baek can use Mental Transmission to communicate directly without an enemy overhearing. She employs it to coordinate attacks and to pass secret information, although its maximum range and resistance limits are not stated. She also has access to a Dimensional Pocket capable of carrying the Imperial Oath when wrapped and suppressed by sacred measures. The pocket is storage utility, not proof that she can neutralize the stele's corruption by herself. (Chapters 145, 151, 153, and 183)

Physical performance and constraints

Baek has the speed, strength, and endurance expected of a top melee Unique Ranker. She can push a person-sized boulder uphill one-handed while using mana, move across wire-thin footholds in combat, fight an Army Commander after extended exertion, and throw a spear with enough accuracy to wound a distant moving target. Her composure helps her preserve energy and avoid unnecessary motions. (Chapters 91–92, 146, and 162)

Her body remains mortal and damage accumulates. She bleeds from direct impacts, sweats under sustained pressure, suffers nausea when overdriving her energy, and enters the final war with an arm left dangling after fighting Twisted Kindness. Healing from the World Tree restores bone, minor injuries, and mana, but that recovery is external support rather than an innate regeneration ability. At her peak she can delay or help kill divine opponents through group tactics; she cannot safely absorb their strongest attacks or defeat the Parasite Queen alone. (Chapters 145–146 and 199–200)

Power progression

Relationships

Seol Jihu

Seol Jihu is Baek's childhood friend, former partner, eventual husband, and the person around whom her two identities finally converge. He first cares for Seonhwa after her parents' death; she later supports him through ordinary life, addiction, and his entry into Paradise. His gambling destroys her trust without destroying the bond, leaving her caught between the desire to save him and the fear that forgiveness will enable another betrayal. Seeing him refuse gambling even after losing his memories persuades her that his change is real. (Chapters 20, 93, 98, and 193)

In Paradise she protects him before he understands who she is. She intervenes at Arden, joins the Spirit Realm expedition under conditions intended to keep him alive, and visits the Path of the Soul. Their conflict repeatedly concerns agency: Baek wants to prevent dangers he accepts, while Seol refuses a safe life purchased by abandoning Paradise. By the Imperial Oath expedition, she can carry out his plan even when doing so means leaving him behind. Her eventual confession replaces covert guardianship with an acknowledged partnership, and the epilogue confirms their marriage and child. (Chapters 94, 142, 162, 183, 193, and 253)

Seo Yuhui

Seo Yuhui is Baek's confidante, wartime peer, and romantic rival. Seo helps create the Baek Haeju identity and later accepts Seonhwa's request to protect Seol. Their mutual secrecy and history in the first Imperial Oath expedition support a durable trust: Baek carries Seo's covert messages, and Seo knows the Earth identity that most of Paradise cannot discover. (Chapters 153, 178, 185, and 193)

They disagree sharply over Seol. Seo rejects Baek's claim to decide whether he should remain in Paradise, while Baek resents that the protector she appointed developed her own attachment. The rivalry never cancels their battlefield cooperation. Seo's barrier saves Baek from Twisted Kindness's fatal counterattack, enabling Baek to complete the thrust that kills the Commander. In the postwar period they work together in the restaurant and enter Seol's extended household while continuing to compete openly. (Chapters 94–95, 200, 204, and 253)

Jang Maldong, Kim Hannah, and Valhalla

Jang Maldong recognizes Baek's intention during Seol's treatment and protects her while their techniques keep him alive. He also regards her as the spear master capable of deciphering an advanced technique beyond his immediate analysis. Their relationship is based on martial credibility and shared responsibility rather than frequent intimacy. (Chapters 94 and 113)

Kim Hannah becomes a practical bridge between Baek and Valhalla. She reserves Baek's share of expedition rewards, tells her when Seol enters the Path of the Soul, and uses the Sacred Empress's presence as part of the coalition's deterrent power. Baek's Level 9 promotion is later counted among Valhalla's new Unique Rankers, formalizing a connection that had begun through selective cooperation. (Chapters 162, 172, and 194)

Sung Shihyun

Sung Shihyun is a former teammate from Baek and Seo's generation. He fights beside them during the first Imperial Oath expedition, but his conduct produces a major rupture with Baek and breaks the team apart. When he returns as a Parasite defector, he tries to provoke her by invoking their past. Baek is furious and admits she has long wanted to kill him, yet she uses Mental Transmission to coordinate rather than letting that anger dictate the fight. (Chapters 101, 151, and 178)

Other comrades and opponents

Baek respects competence and accepts command relationships when they serve the mission. She entrusts tactical reasoning to Philip Muller, accepts Kazuki Ayase's argument that she must carry the stele rather than return for Seol, and sets aside friction with Oh Rahee during major battles. These relationships show a professional flexibility that contrasts with her solitary reputation. (Chapters 142, 148, and 183)

Twisted Kindness is the opponent who most clearly measures Baek's limits and growth. In the Spirit Realm, the Commander can suppress Baek even when she overdrives her power. In the final war, Level 9 reinforced sword qi and the allied formation let Baek hold her in place and eventually pierce her heart, but only after collective attrition and Seo's rescue. The victory is the culmination of Baek's experience as a team fighter rather than proof that she surpasses the Commander alone. (Chapters 146–148 and 197–200)

Items

Tathagata Spear

The Tathagata Spear is Baek's apple-green divine weapon and primary combat conduit. It emits green energy, channels her holy water and sword qi, can split its blade into three extensions that curve like whips, and withstands clashes with Army Commander-class enemies. Baek considers Seol's Spear of Purity potentially stronger, so the Tathagata Spear should not be treated as the setting's uncontested supreme spear. (Chapters 145, 162, and 197)

The spear has consciousness. It buzzes in response to conversation and is capable of an opinion distinct enough that Baek attributes a spoken remark to it, although the scene leaves room for Seol to suspect she is using it as cover for her own embarrassment. Its demonstrated autonomy does not establish that it can fight complete battles without Baek. Most of its effects are produced through her handling, energy, and technique. (Chapter 162)

In the final war, the Tathagata Spear penetrates Twisted Kindness's heart and delivers the last physical blow before the Commander perishes. The narration explicitly notes that an ordinary heart thrust would not have been sufficient; the kill succeeds because the allied force has accumulated severe damage and Seo blocks the intended mutual-kill counterattack. The weapon is therefore decisive without being independently overpowering. (Chapter 200)

Baek also possesses an unnamed appearance-changing artifact recovered from the Dragon's Nest. It creates the visible identity called Baek Haeju and is essential to keeping Yoo Seonhwa's Earth life hidden. The corpus does not name the item, state how it is activated, or show a countermeasure that breaks the disguise, so its mechanics beyond the successful transformation remain unknown. (Chapters 185 and 193)
