Oh Dok-seo

Oh Dok-seo is the reader who recognizes Undertaker as the protagonist of a novel, then becomes the writer and editor responsible for returning his humanity to the account of his regressions. Her literary habits attract Infinite Metagame, but the same insistence on treating stories as relationships rather than disposable fiction ultimately lets her resist, seal, absorb, and outlast the Outer God that chose her.

Biography

From critical reader to the regressor's companion

Dok-seo first enters Undertaker's plans as the blunt web-novel expert who diagnoses why the authors confined in his Canned Hotel have stopped working. Her judgment is practical rather than reverent: writers need pressure, compensation, and readers, not an ideal retreat detached from the reasons they write. That unsentimental expertise makes her useful, but it also reveals how seriously she takes the bond between a story and its audience. (Chapter 23)

When Undertaker follows her through the Busan Station Tutorial in the 555th cycle, Dok-seo initially believes that she has entered the novel she once read. She tries to use that knowledge while remaining wary of the frightening man she thinks is its protagonist. After clearing the station and learning that his regressions are real, she stops treating him solely as a fictional role. Their rapport becomes teasing and argumentative—she calls him an old man, challenges his decisions, and demands honesty—but it is founded on a deliberate promise: when his endless repetitions threaten to reduce everyone to patterns, she will be the person who saves him. (Chapters 24–26)

By the 593rd cycle, Undertaker recruits Dok-seo before their usual trust has time to form because her perspective is essential to hunting Infinite Metagame. The Outer God defines the world as a game and chooses Dok-seo, a self-proclaimed book possessor inclined to see reality as a creative work, as its priestess. Rather than simply obeying Undertaker's optimized route, she helps make that route narratively convincing: the Saintess presents it as a broadcast, Dok-seo accepts the role of player, and their accumulated misfortune becomes the luck needed for a decisive strike. (Chapters 149–152)

Dok-seo then uses SG Net and her knowledge of genre to draw hundreds of Awakeners into contracts with the hidden Admin. Once Infinite Metagame manifests, she refuses the god's attempt to divide reader from protagonist. She argues that seeing Undertaker as a character does not erase his personhood and recognizes that either of them could become monstrous by dominating the other's story. After the Walther PPK creates an opening, she uses the laptop as a vessel and seals the defeated Admin inside it. Her proposed safeguard is reciprocal authorship: she will write Undertaker, he will write the parts concerning her, and neither will possess the whole truth alone. (Chapters 153–159)

Authorship, dependence, and surrender

Possessing the laptop does not end Dok-seo's struggle with Infinite Metagame. She wants to preserve Undertaker's lives in writing, yet repeated deadlines, burnout, and shame leave her vulnerable to the Admin's influence. She experiments with an AI-like writing aid, tries to blame the relic when its prose is exposed, and later attempts to use its power to make future versions of herself endlessly productive. These choices are comic in presentation but consequential: the laptop offers shortcuts that can turn her dependence on a story into the story's control over her. (Chapters 198–203)

The same route establishes that Dok-seo is not merely a protected writer with a conceptual barrier. In the 888th cycle she operates as an experienced anomaly hunter, develops Aura and direct combat skill, and returns from destroying a Great Void alone as part of her routine work. Infinite Metagame's attempts to exploit her burnout therefore coexist with a material expansion of her independence: she can survive and complete missions without Undertaker beside her, even though the laptop remains a route through which the Admin can pressure her judgment and writing. (Chapters 199–201)

Her bond with the Admin also opens paths no ordinary historian could reach. Dreams of the Saintess's frozen world develop into Side Story Creation, allowing Dok-seo to enter another person's perspective and recover lives that Undertaker cannot narrate in order. Infinite Metagame tries to weaponize that gift, increased Aura, and poisoned prose against him, but every attempt fails because Dok-seo values the person more than the role assigned to him. The Admin eventually acknowledges defeat and accepts a treaty reducing it to a constrained ally embodied by the laptop. (Chapters 245, 272–273, and 339–344)

Dok-seo's authority over side stories later carries her into a continuation of the 173rd cycle, where she chooses to show what happened after a moment Undertaker had treated as an ending. She does not use that opportunity merely to observe. When the Regression Alliance plans Project Collapse against Hecate, Dok-seo joins the operation while already existing in a state close to permanent Corruption. She concludes that Infinite Metagame has been absorbed into her so completely that there is no useful boundary between an ordinary and Fallen version of herself. (Chapters 349–360)

That fusion changes the scale, but not the purpose, of her defense. Faced with Hecate's meteor swarm, Dok-seo expands the barrier that once lasted roughly a minute and holds it for ten to fifteen minutes with Sim Ah-ryeon continually healing the stamina cost. The feat protects the entire strike team without making Dok-seo invulnerable: duration and exhaustion remain real limits, and her success depends on another companion's support. She uses an Outer God's legacy as a shield so that Undertaker can reclaim Dang Seo-rin rather than reduce Hecate to another target for extermination. (Chapters 360–363)

Editor at the narrow gate

Dok-seo's final contribution is not simply greater power. Undertaker's perfect memory makes ordinary autobiography impossible because every face and sentence is crowded by countless prior versions. Dok-seo offers to mediate that burden. Wearing the glasses she reserves for private writing, she tells him to give his truth without smoothing away its contradictions; she will impose what order she can and take responsibility for the clashes between his account and hers. In doing so, she becomes both priestess and editor: someone who interprets a voice without claiming to replace it. (Chapter 409)

When the final choice turns toward abandoning Awakening, Dok-seo helps organize the transition but secretly preserves the core alliance's powers long enough to face the question behind the Outer Gods. She recognizes that simply leaving humanity defenseless could recreate the same catastrophe, yet she also understands that keeping miraculous power can repeat the cycle in which saviors become alienated gods. Her confrontation with Infinite Metagame helps expose the Outer Gods as worn remnants of prior human failures. (Chapters 419 and 436–439)

After the Admin dissolves its avatar and remaining power into the manuscript, Dok-seo retains the laptop and continues writing without its voice directing her choices. That outcome completes the reversal of their first bond: Infinite Metagame selected her as a reader it could turn into a priestess, while Dok-seo survives as the editor who can preserve a god's story without being possessed by it. She becomes the custodian of the ark they made together rather than the controlled intermediary of someone else's game. (Chapters 439–440)

Appearance and personality

Dok-seo is introduced with a red bob haircut, a cap, a bandage across her nose, and a favored hoodie—an outfit Undertaker describes as the leading edge of nerd fashion. She later wears a baseball cap low over her face when trying to remain an observer. She also uses glasses while writing, but dislikes being seen in them and normally reserves them for private work. (Chapters 23, 296, and 409)

She is combative, theatrical, and proudly steeped in web novels, games, and chuunibyou affectation. Her sharp tongue makes her a natural critic of Undertaker's solemnity, while her enthusiasm lets her recognize strategies hidden in narrative form. Dok-seo procrastinates, burns out, resents pressure, and is readily tempted by shortcuts, yet she takes editorial responsibility seriously. Her most durable trait is a refusal to let the language of protagonists, readers, NPCs, or side characters decide whose feelings count as real.

Powers, prophecy, and authorship

Dok-seo's powers share a single foundation: she can treat lived reality as a story without fully surrendering the distinction between a person and a character. Infinite Metagame cultivates that perspective because it resembles the Outer God's own authority, but Dok-seo repeatedly turns it toward preservation and mutual interpretation rather than domination.

The Slowest and Fastest Prophet

Her first prophetic state presents the coming catastrophe as a serialized novel. As the Slowest Prophet, she can possess the warning long before the world collapses yet dismiss it as entertainment, especially when the work seems unfinished. The ability therefore includes an epistemic limitation: receiving the text does not make her believe it. Once she reads far enough to encounter herself and accepts that the novel describes her reality, the condition clears and she becomes the Fastest Prophet, awakening before most other people. (Chapters 24–26 and 419)

The prophecy is powerful because it preserves information that should be inaccessible across resets, but it is neither complete nor automatically trustworthy. Dok-seo must interpret missing sections, distinguish warnings from narrative framing, and act before she has Undertaker's accumulated experience. Her later plan accepts repeated failure as part of that limitation: if she dies before the story begins, Undertaker will regress, notice her absence, and create another chance for a later Dok-seo to receive what was learned. (Chapter 419)

Absolute Defense and Absolute Seal

Absolute Defense, also called the AT Field, rejects physical interference within Dok-seo's radius by treating an attack as something occurring inside a creative work rather than directly to reality. The barrier can nullify overwhelming force, but its early form lasts only a little over one minute and is limited to one use per day. Training alone does not readily extend it, and use consumes stamina. Its protection also depends on Dok-seo maintaining the interpretive stance from which she can deny the attack's reality. (Chapters 245 and 419)

As Infinite Metagame's fully awakened priestess, she can sustain a much larger barrier against Hecate's meteor assault. Even then, she estimates only ten minutes of reliable protection, perhaps fifteen with Ah-ryeon's repeated healing. Absolute Seal applies the same logic more broadly: instead of merely rejecting a blow, Dok-seo can bind nested regressions and reincarnations as a story within a story, connecting the surviving reality after the sealed possibilities are contained. These are conceptual defenses, not proof of limitless durability. (Chapters 363 and 419)

Side Story Creation and Main Story Writing

Side Story Creation lets Dok-seo immerse herself in another person's episode and perform from that person's perspective. It gives her access to histories outside Undertaker's orderly recollection, including the Saintess's isolation in frozen time and continuations of cycles that appeared to have ended. The access is psychologically dangerous: dreams are vulnerable to Void contamination, and inhabiting another life can blur observation, authorship, and identity. (Chapters 272–273 and 349–350)

The ability is a spoil of defeating the Mastermind rather than unconditional possession. Dok-seo can inhabit only someone about whom she has already written a side story, and she can write that side story only after the person's life flashes through her mind as a vision. The sequence—vision, authored side story, then possession—limits who she can enter and ties the power to witnessed life rather than arbitrary invention. (Chapter 273)

Main Story Writing is the more assertive extension of that authority. Dok-seo can organize people as characters, recruit allies through the information she possesses, call on Infinite Metagame's status screen, inventory, and map, and arrange repeated attempts around Undertaker's regression. Infinite Metagame tempts her to demote everyone into controllable fiction, but Dok-seo refuses that conclusion. She stakes her life on Undertaker precisely because she believes his trust gives her a responsibility to his real existence, not permission to overwrite it. (Chapter 419)

Priestess of Infinite Metagame

As the Admin's chosen priestess, Dok-seo can communicate with the Outer God, operate its laptop vessel, use game-interface services, and receive power that includes Aura and expanded conceptual authority. The relationship is adversarial as often as devotional. Infinite Metagame tries to shape her into the ideal book possessor, while she mocks it, seals it, exploits its services, and ultimately forces its surrender. Dependence on the laptop can worsen her burnout or invite corrupted writing, so access is never cost-free. (Chapters 151–159, 198–203, and 339–344)

After the surrender, Dok-seo describes herself as fully fused with the Admin and permanently Corrupted, with Infinite Metagame's power absorbed rather than merely borrowed. This state lets her follow a regression axis that should exclude ordinary people and greatly strengthens her barrier. It does not erase her individuality: she remains capable of disagreeing with the Admin, protecting her companions, and choosing how its remaining power will be used. When Infinite Metagame finally dissolves into the manuscript ark, Dok-seo survives as its writer and custodian. (Chapters 360, 363, and 436–440)

Power progression

Relationships

• Undertaker: Dok-seo begins as his reader and becomes his companion, critic, writer, and editor. Their trust is deliberately reciprocal: she preserves the humanity his memory cannot narrate cleanly, while he refuses to treat her as an interchangeable version or a tool for recording his life.
• Infinite Metagame: The Admin chooses Dok-seo because her literary worldview resembles its own. Their relationship moves through temptation, possession, sealing, mockery, reliance, surrender, fusion, and finally a shared manuscript ark; neither simple worship nor simple ownership describes it.
• Sim Ah-ryeon: Ah-ryeon can shame Dok-seo's poor or derivative writing with ruthless accuracy, but she also sustains Dok-seo's expanded barrier during the Hecate campaign. Their later attempts at communal living retain this mix of intimacy, irritation, and practical support.
• Cheon Yo-hwa: Dok-seo befriends Yo-hwa during the speedrun route and benefits repeatedly from her strategic interventions. Infinite Metagame resents Yo-hwa for dismantling its plans, leaving Dok-seo between two brilliant, hostile influences whom she nevertheless treats as allies.
• Jeong Ye-ji: The Saintess helps stage the speedrun that makes Dok-seo a player against Infinite Metagame. Dok-seo later recovers the Saintess's frozen isolation through side stories and participates in the plan to rescue her without creating another Outer God.
• Noh Do-hwa: Do-hwa frequently subjects Dok-seo's enthusiasm to skeptical scrutiny, while Dok-seo uses Do-hwa's planning and authority as part of the wider alliance she assembles across routes.

Items

• Infinite Metagame Laptop: The vessel in which Dok-seo seals the Admin, her writing tool, a regression-persistent interface to the Outer God's powers, and ultimately the manuscript ark left in her custody.
