Cha Eunha is a legendary first-generation pioneer hunter from 1997 who threw herself into the jaws of catastrophe to ensure the survival of her unit. Trapped within a glitched infinite dungeon for what felt like an eternity, she was tempered by relentless combat and isolation before returning thirty years later to a modern, commercialized hunter society. Adopting the alias "Lee Yura" and tagged with the theatrical persona "Burning Flame Princess," she retains the hardened, selfless ethos of the first generation. Beneath her deadpan demeanor and annoyance at modern media culture lies an uncompromising protectiveness toward innocent lives, a deep grief over her lost decades, and a blistering contempt for exploitative guild politics. Powers: Pledged to the 13th Divine Beast ("The Wandering Cat of Darkness"), Eunha wields Level 99 conceptual black flames capable of burning souls, dispelling grand-scale mental illusions, and incinerating gate bosses with single strikes. Her secondary divine authority, Cat's Claw, manifests devastating spatial slashing attacks. Her physical parameters, battle sense, and pain tolerance far exceed conventional S-rank thresholds.

An elite S-rank hunter representing the prestigious Wolf Guild, Shin Siwoo is the public epitome of modern success who secretly suffers from debilitating burnout, psychological exhaustion, and survivor's guilt. Stumbling upon Eunha during an anomalous dungeon collision, he recognizes her transcendent strength and immediately orchestrates her civilian reintegration. Cynical toward the exploitative entertainment machine of modern hunting, Siwoo desires to step back from the limelight, willingly acting as Eunha’s administrative sponsor, legal aegis, and political vanguard so she can operate unhindered. Powers: S-rank combatant specializing in supreme physical augmentation, high-speed vanguard assault, and hyper-acute sensory perception. His tactical acumen allows him to read monster telemetry and association political traps with equal mastery.

Formerly a desperate rookie saved by Eunha’s sacrifice in 1997, Baek Yijun survived to become Korea's undisputed first-generation paragon and an international top-5 ranker known worldwide as "Maestro." Haunted for thirty years by survivor's guilt and the memory of the comrade who died in his place, he has grown calculating, melancholic, and intensely observant. Returning to South Korea under the Hunter Association’s auspices, he directs institutional search operations while covertly unraveling the mystery of the "Burning Flame Princess," torn between desperate hope and protective caution. Powers: High-tier biological authority centered on complex pheromone manipulation. Maestro can command vast swarms of high-level gate monsters, dominate biological beasts, and manipulate psychological states across massive operational radii.

The master of the Legion Guild and the youngest S-rank hunter in South Korea, Minju masks deep childhood abandonment trauma behind the guise of a bratty, military-obsessed youth dubbed "Trickster." Highly suspicious and fiercely protective of his autonomy, he initially clashes with Eunha after securing her lost 1997 dog tag. However, after witnessing her absolute resolve and enduring life-or-death trials alongside her in the Blue Labyrinth, Minju rejects external shortcuts - including divine beast contracts - to forge his own genuine strength, transforming into one of Eunha’s most dependable comrades. Powers: S-rank stealth, psychological warfare, spatial mobility, and illusion-based trickery. He commands lethal tactical weaponry and infiltration arts that allow him to bypass high-grade dungeon security.

A high-strung, incredibly diligent manager who takes on the impossible task of managing Eunha's chaotic entry into modern society. Jehwi bridges the gap between Eunha’s 1990s sensibilities and modern digital entertainment culture, managing sponsorships, broadcast appearances, and guild paperwork. Though non-combatant by nature and plagued by daily anxieties, his courage shines through when his family is endangered, earning Eunha's total loyalty. Powers: Exceptional corporate logistics, media crisis management, public relations navigation, and an encyclopedic knowledge of modern hunter regulations.
