Jin

Jin is the First Seat of the Primordials and one of the hidden architects of Brandon Locke's progression. He tests, recruits, and protects Brandon while withholding the purpose of their connection, works with Ciel to manage the Sovereigns' threatened descent, and disappears after attempting to delay a calamity that arrives three years early. Later testimony and a regression vision connect him to much older designs, but the corpus leaves both his survival and the precise nature of those identities unresolved. (Chapters 51–293)

Biography

The First Seat's rooftop test

Jin first observes the aftermath of Amy Ashfield's rescue and then seals Brandon inside a spatial reality above the city. Introducing himself as the Primordials' First Seat, he reveals that he had killed the real Alpha, Leon, and borrowed the man's appearance to approach the operation unnoticed. The deception is tactical rather than an alternate identity: beneath it, Jin appears as the black-haired, black-eyed man who had arranged the confrontation from the shadows. (Chapters 51–52)

The ensuing test requires Brandon to land a single hit while Jin answers him with spatial portals, black lightning, wind, crystal weapons, and black flame. Brandon eventually cracks Jin's crystal sword and reaches him, earning an invitation to defeat the Eleventh Seat within three years and become Jin's proxy First Seat. Jin then names himself, explains that he ordered Darwin's conspicuous kidnapping to expose Francis Osborn and evaluate Brandon, and executes Darwin once the experiment is complete. (Chapters 52–54)

Mahesvara and calculated intervention

Lucian addresses Jin as Mahesvara, showing that “Jin” is a newer name within an older acquaintance. Their conversation also establishes the scale hidden by Jin's anonymity: Lucian privately regards him as stronger and attributes his own reputation as the world's strongest mage partly to the First Seat remaining unknown. When Jin predicts an attack on the academy, however, he tells Lucian not to interfere, trusting Brandon's improvisation and accepting the danger as part of the progression he is cultivating. (Chapter 67)

Jin later answers Brandon's deliberately alarming hospital message, wakes him with a healing potion, and makes clear that the rescue is a one-time concession. He still refuses to explain the syndicate in full. Instead, he warns that the coming rift expedition will kill its participants and says saving them is necessary before vanishing, continuing the pattern by which personal aid and ruthless strategic pressure coexist in his treatment of Brandon. (Chapters 141–142)

Ciel and the early Sovereign descent

Away from Brandon, Jin spends years suppressing breaches between worlds despite the damage accumulating across his body. He and Ciel compare the progress of Brandon, Raven Blackheart, and Amelia Constantine while discussing the sacrificed original Brandon as a separate person and old friend. Jin identifies the current Brandon as the origin and their Sovereign, admits that he needs a successor for his mantle, and accepts manipulating individual lives because he believes the alternative is an early descent by the Sovereigns. (Chapter 155)

The calamity nevertheless arrives three years ahead of Jin's schedule, which he attributes to the current Brandon's presence and the way that Brandon's will rises around rifts. Jin tells Ciel to find him, calls their parting a goodbye, and enters the void to confront the breach. He directly admits that his SSS+ bottleneck leaves him unable to close it; he can only delay the extending hand. No later ordinary scene confirms whether that intervention killed, displaced, or otherwise removed him. (Chapter 155)

Regression testimony and an unfinished design

The other-Brandon consciousness that manifests inside the protagonist later accuses Jin and Ciel of engineering Skill Weaver, monitoring Brandon through its abilities, and preparing Jin to assimilate his body. The scene presents that speaker as Brandon Locke's dormant prior consciousness, but the wider identity history remains contested. Its testimony is interested and hostile rather than neutral proof; Brandon later finds the tome used to alter portions of his System display, confirming interference without independently proving every assimilation claim. (Chapters 209–212 and 293)

Ezekiel's vision presents an even older history in which a Raven Blackheart survives thousands of failed regressions, works with Ciel, sacrifices regression through a binding vow, and eventually acquires Time affinity before shaping the current progression. Its numbering is internally uneven, and the sequence is revealed as dramatized history rather than a present-timeline advancement. The vision associates this regressor with Jin's design, but it does not make Jin interchangeable with the current Raven, current Brandon, or original Brandon; his endpoint remains unresolved through Chapter 430. (Chapter 258)

Appearance and personality

Jin's ordinary appearance is marked by jet-black hair, ink-black eyes, a black blazer, and an abyss-like gaze. He can conceal himself behind another person's form, most notably when he impersonates Alpha after killing the real Leon. His voice is monotonous, his smiles lack warmth, and even his amusement can sound lifeless or eerie to people who know him. (Chapters 51–54 and 67)

He is patient, secretive, and relentlessly instrumental. Jin can heal Brandon, respect the original Brandon's sacrifice, and devote himself to preventing catastrophe, yet he also manufactures danger, withholds decisive information, and kills a disposable accomplice once a test is over. His repeated desire for events to become “different” exposes both his hope and his desperation: disruption matters to him even when he cannot predict whether the new outcome will be better. (Chapters 54, 67, 141–142, and 155)

Magic and abilities

• Space affinity and reality control: Jin isolates a rooftop within a private reality, opens portals for movement and attack, redirects projectiles, and materializes openings at precise positions. His reach includes movement into the void surrounding an interworld breach. Sustained suppression of breaches consumes enormous mana and leaves cracks across his body, and he explicitly cannot close the Chapter 155 rift. (Chapters 52–54 and 155)
• Crystal constructs: He creates black crystals, a crystal sword, spikes, and a lethal rain of constructs. The sword withstands Brandon's elemental offense before Brandon finally cracks it, while the falling crystals kill Darwin after the test. (Chapters 52–54)
• Elemental breadth and combat adaptation: Jin uses black lightning, wind, and black flame alongside crystal and Space magic, frequently reproducing or countering Brandon's chosen approach. His speed, casting control, and reflexes let him dominate the test while deliberately limiting the victory condition to one successful hit. (Chapters 52–54)
• Zone: Jin can activate a Zone, the advanced domain associated in the narration with four-star mastery. Lucian activates Cocytus a fraction of a second sooner during their standoff, but still considers Jin the stronger mage overall. The exchange confirms Jin's access without defining a named form or every effect of his own Zone. (Chapter 67)
• Sovereign-system knowledge: Jin calls the System the Sovereign's Will, understands its instability around rifts, and helps Ciel alter parts of Brandon's displayed quests and statistics through a tome. The original Brandon further alleges that Skill Weaver gives Jin sensory and bodily access intended for assimilation, but this purpose remains testimony rather than a fully demonstrated ability in Jin's own scenes. (Chapters 155, 209–211, and 293)
• Regression and Time evidence: Ezekiel's vision attributes thousands of regressions, their eventual sacrifice, and later Time affinity to the historical figure tied to Jin's scheme. Because this is a compressed vision with inconsistent numbering, it establishes structural history more safely than a measurable current-timeline technique or rank increase. (Chapter 258)

Power progression

Relationships

• Brandon Locke: Jin chooses the current Brandon as a candidate to inherit his mantle, tests him, offers him a path into the Primordials, and intervenes selectively to keep him alive. His care is inseparable from surveillance and manipulation. Jin also calls the earlier Brandon his old friend and respects that person's sacrifice, but the corpus does not fully reconcile that figure with the other-Brandon consciousness manifested in Chapters 209–212. (Chapters 52–54, 141–142, 155, and 209–212)
• Ciel: Ciel is the Second Seat and Jin's long-term collaborator in monitoring the progression, altering Brandon's System presentation, and preparing for the Sovereigns. Jin entrusts her to find Brandon when the calamity begins, although their dialogue shows that she is less comfortable than he is with the human cost of their plan. (Chapters 155, 200–215, and 293)
• Lucian Frost: Lucian knows Jin from his Mahesvara identity and regards him as the power concealed behind Lucian's public reputation. Their familiarity permits argument and a competitive Zone exchange. Jin also judges Lucian capable of closing a dangerous rift and privately relies on that possibility, but the text does not show Jin directly ordering that incursion. (Chapters 67 and 155)
• Raven Blackheart: Jin monitors Raven as one of the important variables in the current progression. Ezekiel's vision associates Jin's design with a regressing Raven from older timelines, but the current academy student remains a separate character and is never interchangeable with Jin in present events. (Chapters 155 and 258)
• Amelia Constantine: Jin identifies Amelia as close to the Sovereign-linked group but not identical to its core members. Her connection to Ciel complicates the history discussed in the regression vision, yet Jin treats Amelia, Ciel, and the other counterparts as distinct operational identities in the current progression. (Chapters 155 and 258)

Items

• Ciel's Fate Tome: Ciel uses the tome to monitor the expected development of Brandon's Sovereign system, and Brandon later identifies it as an instrument Ciel and Jin used to configure portions of his quest and statistic displays. Its physical recovery confirms tampering while leaving the full reach of Jin's access uncertain. (Chapters 200–215 and 293)
• Alpha's burner phone: While impersonating the dead Alpha, Jin uses the disposable phone to coordinate the staged kidnapping and expose Francis Osborn. It is an operational prop rather than proof that Alpha and Jin are the same person. (Chapters 52–54)
