Yu Jitae

Yu Jitae is the Keeper of Vintage Clock, a human trapped in repeated regressions after dragons destroy Earth. By the seventh iteration he has reached the limit of a mortal through warfare and sovereign hunting, but his decisive challenge is no longer gaining power. He takes four dragon hatchlings into one household, tries to give them an ordinary Amusement, and gradually learns to regard their lives—and his own—as more than pieces in an apocalypse-prevention plan.

Biography

The Seventh Iteration and a Stolen Household

After six failed timelines, Jitae begins the seventh as a man who cannot remain dead and no longer expects personal happiness. He understands the apocalypse as a consequence of hatchlings dying or completing miserable Amusements, so his new plan is preventive and coercive: gather the four dragons first, keep them under observation, and produce enough good memories that their adult kin will have no reason to destroy Earth. At this stage he thinks of the children primarily as dangerous variables, even while deciding that ordinary life may succeed where violence failed. (Chapters 1–3)

His first encounters immediately test that detachment. Bom reads danger in him but accepts a provisional home; Yeorum is found fighting in Africa, and Jitae saves her after Javier Karma defeats her; Kaeul follows food and attention; and the blue egg that will become Gyeoul enters his custody with them. He names the hatchlings after the seasons and brings them into Lair under the invented Yu household, replacing his old habit of domination with the unfamiliar work of housing, feeding, registering, and accompanying children. (Chapters 2–9)

The arrangement changes him before he admits it. He destroys the traffickers who threaten Bom, supports Kaeul's desire to perform, guards Gyeoul through hatching and polymorph, and refuses to let Yeorum's confrontations be decided by adults using her for status. Kaeul's emotional immersion exposes her to the cold values and trauma he carries from earlier lives, making him confront how readily his damage can pass to a child. By the entrance ceremony, “guardian” has ceased to be merely a cover identity, although Jitae still insists that the hatchlings' safety is an objective rather than affection. (Chapters 10–38)

Demons, the Abyss, and the Meaning of Daily Life

Jitae balances household routines with threats that only his repeated lives let him anticipate. He sends his first autonomous shadow into the demon organization while teaching the dragons to function inside Lair, then accepts family camping, cooking, games, and Gyeoul's first words as useful parts of the plan. Her dream identifies him as a father, while his willingness to sit beside the children through small fears begins making the domestic role emotionally real. The contrast is deliberate: he can erase hostile organizations, yet has to learn ordinary reassurance one awkward gesture at a time. (Chapters 39–47)

When Ha Saetbyul reappears as Prototype X, Jitae refuses the efficient solution of killing her. She was the person he loved in his second iteration, although the present woman does not share those memories, and his choice reveals an attachment that survived regression. Using Arma's Longsword, he follows the hostile power into the Abyss, destroys the sword to sever its conduit, forces Lakshata to annul Saetbyul's contract, and places her under BM's care. The rescue turns a former failure into a living responsibility instead of another erased casualty. (Chapters 47–54)

The Masquerade then brings Jitae's hidden war into the open. He removes Wei Yan, Melissia, and Noah as catastrophe-level threats, endures Noah's dream worlds, and returns to Unit 301 exhausted enough for the children's welcome to relieve him in a way victory cannot. He also begins teaching Yeorum the Karl-Gullakwa foundation, accompanies Bom against Hasegawa, and accepts Gyeoul's revelation-driven wish to protect him. By the end of this period, daily life is no longer camouflage around the mission; it is the place to which he wants to return after carrying it out. (Chapters 55–102)

Guardianship Under Public and Institutional Pressure

Yeorum's rise in Lair's Campus Competition forces Jitae to act as teacher, guardian, and public representative at once. He compresses years of Karl-Gullakwa preparation into a brutal sequence of breathing and walking under the Chains of Hell, but he also holds her hand while she relearns movement and immediately praises earned progress. When a bribed munitions employee supplies defective protective necklaces for a dungeon raid, Jitae attacks the department, defeats Sillardo Leo, accepts arrest, and uses BM and Myung Yongha's support to make the “Yu household” institutionally untouchable. (Chapters 102–120)

Yeorum validates his training during the fissure raid by using Pulsation, Breathing, and Spark to kill the Spider Queen. Her real need is not merely a ranking: she asks him to confirm that her life and effort have value, and his unhesitating approval becomes one of their defining exchanges. Jitae's response shows how far he has moved from treating the red dragon as a weapon. He still demands competence and accepts consequences for misconduct, but his instruction is now directed toward helping her survive her future Selection Ceremony as herself. (Chapters 121–145)

The same change governs his care for Gyeoul and Kaeul. He stays beside Gyeoul through an early, painful shedding, suppressing his own authorities and blessings so his presence will not disrupt her development; influenced by her request that he become kinder, he spares a young sea devil after killing the adults attacking her. When Kaeul struggles with performance, Chirpy's departure, and the burden of becoming a guardian to others, Jitae gives her choices and preparation rather than deciding her identity for her. The household's needs increasingly modify the methods of the once-inflexible Regressor. (Chapters 146–172)

Affection, Guilt, and Chosen Responsibility

Lair's festival and the household's small celebrations make Jitae aware that he experiences authentic happiness through the dragons. Vintage Clock opens a new “Room” after such moments, but emotional growth also exposes guilt he had kept outside his seventh-iteration plan. Bom's dream of imprisonment recalls the timelines in which he abducted and dissected hatchlings; frightened that closeness will uncover those acts, he pushes her away and causes her to leave. His instinct is still to control danger by creating distance, even when the danger is his own shame. (Chapters 173–215)

He nevertheless keeps choosing responsibility over erasure. When BM's first attempt to recreate Jung Taebaek produces a lethal parasitic chimera, Jitae preserves the child's body in the Shallows of the Abyss and leaves room for BM to grieve and try again. He guides Kaeul from failed healing toward combat magic that can protect others, and he supports her choice to search for a victim's family even when it costs test points. These decisions show a guardian learning that preventing every painful choice is neither possible nor desirable; what matters is staying present for its consequences. (Chapters 185–230)

Bom's return forces Jitae to stop dismissing their bond as a side effect of the mission. He recognizes jealousy, supports her writing, and accepts her kiss, though fear of exploiting the relationship makes him halt further intimacy. In Vintage Clock's basement, eleven emotion-linked obelisks reveal that daily life has opened a route beyond the mortal limit he once reached through killing. Jitae initially wants records of his atrocities to extinguish his affection, but the four dragons confront his impulse to flee, and he chooses to remain in the household while acknowledging that the present bond cannot simply be cut away. (Chapters 231–250)

Season, Myu, and the Limits of Control

As the First and Second Nights approach, Jitae builds an institutional defense under the identity Season. He and Clone 1 force the Association to recognize the prophecy, take the office of Chief Advisor, and compel its leaders to resume their duty as soldiers rather than political managers. He warns Chaliovan not to treat him as an Association weapon, restores the real Jung Taebaek through the living seed BM locates, and protects Kaeul's team from Tower-linked manipulation. His authority broadens, but he repeatedly frames it as a tool for keeping people alive rather than a title he values. (Chapters 193–273)

His teaching of Yeorum reaches its clearest partnership in the Tranquil Sea. When she breaks under the pressure of a deeper dive and asks to stop, Jitae does not shame her or continue directing from safety. He suppresses his protections, injures himself to reproduce her condition, and descends beside her. They survive the sea's traps and hallucinations together, enabling Yeorum to expand her mana capacity and understand that Karl-Gullakwa's sequence taught her how to live. The episode turns their hierarchy into earned trust: he remains her teacher, but accepts the burden as her partner. (Chapters 274–284)

The search for Q leads Jitae to Myu, a mutant black dragon hidden inside the Tower. Their battle devastates Australia; he defeats her with the fifth form of Shapeless Sword but preserves her life because her accessible Origin Fragment may answer the question that has governed his regressions. He subjects her to invasive experiments and coercive confinement, rationalizing cruelty as necessary while gradually responding to her as a person. His success therefore carries the old contradiction forward: he can protect the household while still treating an outsider as material when fear and purpose demand control. (Chapters 285–305)

Farewells, the Clock, and the Truth Behind Hostility

As the dragons mature, Jitae begins preparing for separation rather than pretending the household can remain unchanged. He lets Kaeul return through Anum to protect Chirpy's world, gives her the Authority Adaptor so the Keeper's guidance can reach her, and arrives only after she has made her own decisive choices. In parallel, his work inside Myu's conceptualized heart finds the Origin Fragment and the blocked first memories around it. What began as dissection gradually becomes a shared passage through Myu's loneliness, during which Jitae reveals the thousand-year dream he has never entrusted to anyone else. (Chapters 306–355)

Oscar Brzenk's attack draws Jitae into the Safe, the only Level 6 artifact on Earth and a trap leading to the Temple of Providence. The Judges accuse him of creating Hostility through information leaked across regressions and of depending on Vintage Clock's personality. When the white bird dies after sacrificing itself for him, Jitae rejects the Temple's right to reduce that loyalty to incompetence, breaks its Bridle, and threatens to punish the Judges themselves. The confrontation makes his loyalty reciprocal: the authority that once merely imprisoned him in time has become a friend whose death he mourns and defends. (Chapters 356–369)

The cost returns home. Bom's attempts to protect him become controlling and violent, while Jitae's accumulated fear culminates in striking her; both recognize that love has magnified rather than erased their damage. Vintage Clock's final message confirms that Jitae has long intended to send the dragons home and die once the seventh iteration is safe. Bom chooses to help with the farewell despite wanting him to live. Jitae prepares the Dimensional Cruise, listens to each child's attempt to bargain for more time, and still carries out the departure because he believes their survival matters more than his loneliness. (Chapters 369–389)

The Cruise, Hostility, and the Choice to Live

After the cruise leaves Earth, Jitae moves toward the death he has treated as the natural end of his duty. Key warns that the ship may be in danger, but he initially answers with indifference because he believes returning the children to Askalifa has completed his responsibility. Memories of their ordinary life and the last message of the white bird break that conviction. Under Defrost, with his resistances stripped away, he finally admits that he does not merely want the dragons safe: he wants to live, see them grow, accept condemnation, and repair what he can. (Chapters 390–398)

Inside the cruise he discovers that Bom is both a green-black hybrid and the Hostility acting beyond the Horizon of Providence. Her mother was Lugiathan, the black-dragon sovereign Jitae killed in the sixth iteration to steal Conceptualisation, and her preserved memories turn his erased atrocities into a living grievance. Jitae cannot refute the death or the dissections behind her revenge. Instead, he acknowledges that the hatchlings taught him to love the children of enemies, asks Bom to spare the others, and offers his future labor toward her goals as atonement rather than demanding instant forgiveness. (Chapters 398–403)

Bom cannot kill Yeorum, Kaeul, or Gyeoul, but she also cannot imagine living beside her mother's killer and turns the weapon on herself. Jitae's grief lights the last emotional obelisk, granting a restrictive Transcendent Authority. The moment is not a conventional victory: the household survives, yet Bom's death proves that safety without truth was never enough. Jitae rejects the inner “Sin” that urges him to discard her and keep only the easier happiness of the other three. His chosen future must include responsibility for Bom, or it is not the happiness he learned to want. (Chapters 403–405)

Atonement Across Time

Using Conceptualisation (EX) on his own Sin, Jitae enters a parallel reconstruction of the sixth iteration and meets Bom as a child. He builds trust without revealing their full history, then prepares the black-dragon palace for the assault of his earlier self. His goal is not to excuse the sovereign hunt but to remove its originating wound: prevent Lugiathan's permanent death, keep the young Bom from reliving the same despair, and cut the chain by which her memories become Hostility. The plan demands cooperation from the child whose future he damaged, making atonement an action rather than an argument. (Chapters 405–412)

Jitae fights his sixth-iteration counterpart with the same stolen authorities and Shapeless Sword forms, spending half his remaining killing intent on the final Punishment strike to buy time. He sends young Bom outside, binds the palace pillars with Chains of Hell, and collapses the building over the entrance to Primal Time. This seals the earlier Regressor away from Lugiathan's family and rewrites the relevant Providence, but also strands the present Jitae beyond ordinary time. He accepts the apparent death because it restores the lives and future he had taken, even though he now desperately wants to live. (Chapters 409–413)

The altered memories reach Bom and erase the timeline in which her revenge ends in suicide. Across centuries she reunites the seasonal dragons, completes her Grand Schema, and creates the white bird that will accompany the lonely young Jitae, finally drawing him out of the Non-Providential World. He awakens near the beginning of his human life with the accumulated memories and body of the Regressor, then finds Bom waiting with her own memories intact. Their reunion establishes a new beginning in which neither must pretend the past did not happen. (Chapters 413–425)

A Rewritten Beginning and Shared Future

In the restored life, Jitae and Bom rebuild the household as the other dragons return in younger forms with their memories. Gyeoul hatches again from a scaled-down egg, Kaeul resumes her affectionate dependence while also bringing the maturity of her long life, and Yeorum again asks him to train and fight with her. Jitae is no longer preparing to abandon them after a single Amusement. His strength remains formidable, but domestic continuity—not apocalypse management—now determines how he uses it. (Chapters 426–430)

His relationship with Bom also becomes openly mutual. The two confront her lingering fear that happiness may end beyond the portion of Providence she has seen, and Jitae answers uncertainty by remaining with her rather than demanding proof of permanence. Their intimacy is presented alongside training, teasing, work, and the other dragons' interruptions, making romance part of the same daily life that once seemed impossible to him. The future is not guaranteed by perfect foresight; it is sustained through continued choice. (Chapters 431–433)

The final household scenes leave Jitae alive, surrounded by the four dragons and the ordinary noise of their shared home. That state completes the reversal begun in the first chapter. The man who entered the seventh iteration expecting only to stop an apocalypse now has a family that remembers him, a partner who crossed time to retrieve him, and a reason to accept an unwritten future. His ending is not release through death, but the ongoing responsibility and pleasure of living together. (Chapter 434)

Appearance and personality

Jitae is slightly under 190 centimeters tall, with broad shoulders, thick arms and wrists, and a reverse-triangular soldier's build shaped by multiple authorities. He has thick eyebrows, a stiff gaze, and an oppressive presence that makes strangers compare him to a murderer or monster even when he is doing ordinary work. His expression is usually indifferent, and Temporary Body Modification lets him alter his face for covert activity, while Inherent Customisation automatically fits clothing and equipment to his body. (Chapters 56, 60, 116, 126)

At the seventh iteration's start he is utilitarian, controlling, and frighteningly comfortable with violence. Repetition has reduced cities, institutions, and even people to predictable variables, so he habitually chooses the shortest reliable solution and struggles to understand social nuance. Yet he is not careless: his routines are exact, he studies motives and contingencies, and he accepts physical suffering without complaint when it protects an objective. These traits make him both an extraordinary guardian and a man capable of rationalizing abduction, torture, and dissection. (Chapters 1–10, 47–50, 245, 300–302)

Daily life restores qualities he had buried rather than supplying an entirely new personality. He becomes patient with Gyeoul's speech, proud of Yeorum's effort, protective of Kaeul's fragile confidence, and playfully responsive to Bom's teasing. His humor remains dry and his affection often appears through practical acts—food, training plans, quiet supervision, or a hand on someone's head. Because he observes heartbeats, breathing, gazes, and danger almost compulsively, the children experience his vigilance as dependable safety even when he cannot articulate tenderness. (Chapters 57–65, 107–145, 173–184, 353)

His central moral conflict is the gap between responsibility and control. Jitae repeatedly believes that knowing more gives him the right to decide for others, whether by kidnapping hatchlings, managing Yeorum's future, experimenting on Myu, or planning his own disappearance without consultation. By the ending he does not erase that history or claim innocence. He chooses life, accepts that atonement may outlast forgiveness, and relinquishes the demand to know the future before loving someone. His persistence remains, but it is redirected from perfect control toward remaining present. (Chapters 306–313, 369–405, 425–434)

Powers and abilities

Jitae reached the limit of a mortal before the seventh iteration. After the fifth timeline he trained through repeated death, sword practice, and mana-trace control, then hunted nearby sovereigns—including Demon Archduke Baal, black-dragon chief Lugiathan, and other rulers—and absorbed their powers. His arsenal therefore combines human combat experience, stolen sovereign authorities, artifacts, and the support of Vintage Clock. It is broad enough to overwhelm top world rankers and adult dragons, but several powers have costs, jurisdictional limits, or effects that can be countered by equal or higher authority. (Chapters 245, 291–296, 347–355)

Vintage Clock, regression, and Key

Vintage Clock (EX) is the authority responsible for keeping dimensional records moving and can control the flow of time in designated dimensions under restrictions. The Temple of Providence selected Jitae as its Keeper because his will was the strongest among humans; when a timeline fails, the authority returns him while preserving the knowledge that makes later iterations possible. Jitae does not freely command every aspect of it, and the Clock can refuse, warn, or act through its own white-bird personality. A special sixth-iteration concession lets him set a regression starting point in an outer dimension, but that exceptional weapon also becomes the problem his later self must seal away. (Chapters 1, 245, 361–368, 409)

Vintage Clock's Workshop stores records of his iterations, while Key (EX) opens the basement formed by his recovered emotions. Eleven obelisks respond to authentic experiences such as happiness, greed, fear, and sorrow; lighting all of them grants a restrictive Transcendent Authority rather than a general rise in every combat statistic. Key can assess danger and open otherwise inaccessible routes, but cannot see into the outer dimension around the cruise. At the climax, the completed emotional structure makes Conceptualisation's EX use possible, after which Jitae changes a past causal wound instead of initiating another ordinary regression. (Chapters 179–180, 244–250, 284, 395–405)

Shapeless Sword and physical combat

Shapeless Sword (SS) gives form to Jitae's accumulated killing intent. It can manifest as an invisible blade, expand to enormous size, bend around defenses, or assume specialized forms developed through repeated combat. The fifth and final form, Punishment, condenses the urge of innumerable existences to kill, die, or end repetition into a thrown or thrust spear; it grievously wounds Myu and later pierces the sixth-iteration Jitae. Its power is not limitless: the final use permanently consumes half of Jitae's remaining killing intent, explicitly reducing a finite reserve that had fallen to roughly nine hundred. (Chapters 10, 24–25, 62, 291–294, 413)

His body supplies the speed, durability, and control needed to use that weapon at sovereign scale. He accelerates beyond sound, survives injuries that would immediately kill ordinary superhumans, and can overpower Sillardo Leo or fight a black dragon across hundreds of kilometers. Sixth Sense reads danger and the world's flow even when ordinary sight is compromised, although Noah's altered dream framework temporarily blinds that orientation. Jitae can suppress his authorities and blessings to reproduce a student's vulnerable condition, and his best teaching moments arise when he accepts that limitation beside Yeorum rather than demonstrating untouchable superiority. (Chapters 80–81, 116–118, 140, 274–284, 291–296)

Authorities stolen from sovereigns

Eyes of Equilibrium (SS), one of three powers taken from the Demon Archduke, displays a target's nature, authenticity, favorability, and identifiable abilities. Jitae uses it for interrogation, counterintelligence, and social threat assessment, including detecting hidden hostility around the Yu household. It reports what is true within its categories rather than granting omniscience: Bom can tell him true statements while her origin and long revenge remain unrevealed, and Providence-level secrets still require separate investigation. (Chapters 13, 24–27, 76, 120, 399–400)

Shadow of an Archduke (SS) creates autonomous copies with their own egos, partial memory sharing, and bodies modeled on selected periods of Jitae's life. Clone 1 reflects the hardened sixth iteration and becomes an independent infiltrator and Association operative; Clone 2 resembles the lonely fifteen-year-old first-iteration Jitae. Creation consumes a rare Level 5 artifact, and Jitae deliberately withholds memories that could distort a clone's personality. He can communicate across the mental link, temporarily sever it, recall a clone into the authority, or let the copies make judgments that expose parts of himself he no longer recognizes. (Chapters 10, 37, 43, 145, 193–205, 306–314, 361)

Punishment of an Archduke (SS) summons fallen angels by temporarily taking power away from Jitae's true body. The troop can overwhelm groups, capture targets, and fight independently, but weakening the original makes it unsuitable for casual use and Jitae rarely invokes it. Conceptualisation (SS), stolen from Lugiathan, interprets minds, memories, powers, and environments as manipulable conceptual spaces; it lets him traverse Myu's internal library and identify personality, dispositions, and memory barriers. A higher-ranked Black Wall defeats the SS interpretation, forcing him to narrow the target. Its restrictive EX expression can analyze Sin and construct the parallel causal intervention that saves Lugiathan's family. (Chapters 67, 245, 347–355, 400, 405–413)

The Abyss, destruction, and utility skills

Jitae's internal alternate dimension progresses from Shallows of the Abyss (S) through Deeper into the Abyss (S+), Depths of the Abyss (SS-), and Very Depths of the Abyss (SS). The Shallows functions as storage and a transport space, with white hands that retrieve objects or carry occupants; its altered time also preserves Jung Taebaek's body. Deeper levels exert increasingly oppressive demonic conditions and provide the route by which Jitae reaches Lakshata's domain while carrying Ha Saetbyul. The depths are dangerous environments rather than effortless teleportation, and their most extreme use exposes both traveler and target to hostile pressure. (Chapters 10, 37, 47–54, 185–192, 277)

Eradication (S) is a destruction-attribute skill obtained from an unnamed black dragon. It violates ordinary physics to combust or erase its target and is effective against bodies, structures, and massed threats. Spatial Severance (S+) blocks movement through a bounded area and can prevent even an earlier Jitae from escaping, but breaking it conveys information about the breaker and equal powers can damage it. Other demonstrated tools include Temporary Body Modification, Inherent Customisation, a precise low-grade Knifehand Strike used for nonlethal incapacitation, flight, dimensional storage, artifact ignition, and the deliberate locking or release of his own blessings and resistances. (Chapters 2, 6, 10, 60, 67, 80–81, 290, 397, 409–413)

Power progression

Relationships

Bom

Bom begins as the hatchling most capable of negotiating with Jitae and becomes the person who reads his silences, challenges his emotional distance, and shares his desire for a home. Their attraction is damaged by his concealed experiments and by her identity as Lugiathan's daughter and Hostility. Jitae ultimately asks for time to atone rather than absolution; after both alter the causal wound across centuries, they reunite as lovers who remember the truth and choose an uncertain shared future. (Chapters 2–3, 107–110, 206–250, 347–355, 369–425, 431–434)

Yeorum

Yeorum is Jitae's student, ward, and eventual partner in survival. He recognizes that her pursuit of strength comes from the red dragons' lethal Selection Ceremony, teaches her Karl-Gullakwa from its heartbeat foundation, and repeatedly verifies effort she cannot value alone. His methods can be severe enough to reproduce fear and death pressure, but the Tranquil Sea marks a decisive change: he enters the same pain instead of commanding outside it. Yeorum's later confidence rests on the trust he gave before she could trust herself. (Chapters 5–8, 14–18, 55–58, 89–124, 152–157, 274–284, 336–343, 386–389, 419–421)

Kaeul

Kaeul teaches Jitae that protection includes a child's identity, not only physical survival. He supports her performance ambitions, corrects public attacks without forcing her from the stage, and later redirects her failed healing into protective combat magic. When she becomes responsible for Chirpy and Anum, he gives her access to his guidance but waits for her to make the crucial choices. She sees him as guardian, parental comfort, and the example she consults when she must become a guardian to others. (Chapters 7–8, 19–33, 70–72, 135–144, 169–177, 216–230, 306–313, 417–418)

Gyeoul

Gyeoul forms the most openly filial bond with Jitae. She sees him as a father before he accepts the word, gives him one of Gyeoul's Keepsake Necklaces, and receives his constant care during hatching and shedding. Her requests that he be less angry and help others directly change his conduct, while her uncomplicated happiness first reveals the new Room in Vintage Clock's Workshop. In the restored life she returns as an egg and hatches into the same household, making their bond something neither regression nor age removes. (Chapters 21–23, 44–46, 57, 64, 165–180, 193–198, 297–299, 377–381, 414–416, 426–427)

Clones, allies, and former attachments

Jitae's shadows are not disposable duplicates. Clone 1 is his hardened operational mirror, while Clone 2 preserves the anxious, idealistic youth he once was; their separate judgments let him test whether a created self can form independent desire. BM becomes a reluctant ally whose labyrinth protects people Jitae saves, Myung Yongha lends the Yu household public legitimacy, and Ha Saetbyul remains a former love whom Jitae rescues without claiming the present woman as his partner. His developing respect for Myu similarly complicates a relationship that begins with imprisonment and experimentation. (Chapters 47–56, 117–119, 145, 185–205, 250–305, 314, 347–368)

Items

• Arma's Longsword is lent to Jitae through Bom's reading of Providence. He uses it as the material link for reaching Hostility and destroys it while forcing Lakshata to release Ha Saetbyul. (Chapters 47–50)
• Authority Adaptor is a bracelet through which Jitae lends Kaeul access to the Keeper of the Clock's guidance during the crisis in Anum. He retrieves it after she succeeds so that its extraordinary connection does not remain exposed. (Chapters 306–313)
• Dimensional Cruise is the outer-dimensional vessel Jitae built in the sixth iteration and later prepares to return the hatchlings to Askalifa. Its defenses are extremely strong against external attack, but Bom compromises the journey from inside. (Chapters 382–404)
• Dream Eater is the Level 4 sword Jitae takes after killing Noah. He lends it to Clone 1 during the First Night, then keeps it as a farewell gift for Yeorum. (Chapters 80, 204–205, 389)
• Gyeoul's Keepsake Necklaces pair Gyeoul's scale and hair with a portion of Jitae's hair. He keeps the necklace she gives him, making it one of the household objects that records a bond he once expected time to erase. (Chapter 64)
• Gyeoul's Memory Crystal records the household's last stargazing trip and is mounted in a necklace as Gyeoul's farewell gift to Jitae. He refuses to watch it while preparing to die, but its destruction releases the stored memories into him and restores his desire to live. (Chapters 378–381, 389–390, and 397)
• Onion Core is an output-amplification core whose first layer is opened by Gyeoul and whose next five are opened by Bom, bringing it close to three times the original output. All ten layers are open by Yeorum's later ranking duels, although the intervening four openings are not shown. It is installed in Yeorum's Level 3 sword artifact and supports the weapon during her late training and farewell duel. (Chapters 314–316, 336–343 and 386)
• Origin Fragment is normally embedded beside a hatchling's dragon heart and inaccessible without killing the dragon. Myu's mutant anatomy lets Jitae investigate one directly, turning it into the central object of his experiments and his attempt to understand the regressions. (Chapters 168, 277, 294, 300–302, 347–355)
• Safe is Oscar Brzenk's four-meter Level 6 artifact at the Association's seventeenth branch. Jitae knowingly opens it as a trap because it provides the route into the Temple of Providence, where he confronts the Judges over Vintage Clock. (Chapters 358–368)
• The Preservation Coffin carries BM's prepared restoration ingredients while Jitae climbs toward Taebaek's preserved body, and the Seed That Allows the Dead to Breathe supplies the living heart at the summit. (Chapter 262)
• The Shadow Artifact Bodies consume two rare Level 5 artifacts to embody Clone 1 and Clone 2 as separate sentient individuals. (Chapters 3, 145, 149)
• Wyvernip is the calming black flower Jitae buys for the household after their first specimen withers; his encounter with Myu while seeking it later helps him identify the suspected black dragon. (Chapters 285–286, 289–292)
