A legendary ancient barbarian chieftain and the holy warrior of myth who concluded the First Holy War centuries ago. Petrified in stone and preserved into the modern era as a museum relic, Wolfgang awakens into a hyper-capitalist world dominated by Hunter agencies and weak-willed contractors. Uncompromising, ruthlessly pragmatic, and fiercely honorable, he views modern hunters as pampered weaklings crippled by reliance on divine crutches. Driven by an ancient vendetta against the demonic entity "Devil House" - the architect of his historical agony - Wolfgang navigates modern civilization with crushing physical superiority, absolute toxin immunity, and an unshakeable warrior code. Powers: Primordial Barbarian Physiology: Complete immunity to all natural and magical poisons, acids, and neurological toxins; boundless stamina; impenetrable muscular density. Sovereign Aura & Anti-Constellation Nullification: Can project a terrifying, unpolished martial pressure capable of shattering holy relics, dispelling divine constellation blessings (including Leonidas I), and stunning S-rank hunters. Ancient Weapon Mastery: Absolute lethality with bare fists, claymores, broadswords, and consecrated warhammers; adept at wielding holy-blessed armaments without submitting to angelic pacts.

An archaeological hunter and historian whose academic curiosity unearths Wolfgang from his petrified slumber. Intellectually sharp, grounded, and empathetic, Yerin quickly realizes that Wolfgang is neither an eccentric cosplayer nor a standard awakened hunter, but an ancient myth in the flesh. She takes financial and legal responsibility for him, serving as his modern cultural interpreter, dungeon navigator, and bureaucratic shield against predatory agencies like Mu Agency and the Hunter Association. Powers: Archaeological Arcana: Specialized detection spells, artifact appraisal, deciphering ancient scripts, and dungeon barrier analysis. Spatial Relic Navigation: Wields modern teleportation markers and spatial relocation scrolls, serving as the logistical extraction backbone for Wolfgang's high-collateral engagements.

An F-rank outcast at the prestigious Akademie in Seoul, historically ridiculed and overshadowed by his aristocratic peers and toxic family members. In desperate pursuit of power, Jin-woo was on the verge of signing ruinous, self-destructive dark contracts before Wolfgang violently intervened. Wolfgang recognized Jin-woo's buried resolve and forced him to cast aside borrowed constellation cheats. Rebuilt from the ground up through punishing, bone-breaking physical regimens, Jin-woo embraces the arduous path of a pure front-line shieldbearer. Powers: Pure Shield Arts (Barbarian Fundamentals): Kinetic dispersion, center-of-gravity stabilization, stance rooting, and brutal shield-bash blunt trauma without mana expenditure. Unyielding Tenacity: Surging psychological pain tolerance developed under Wolfgang’s relentless life-or-death sparring.

The S-rank master of the elite Sun Guild, revered across South Korea as an apex combatant. Kim Hee-yeon carries the immense burden of corporate expectations and civilian protection, leading her to push her body beyond mortal tolerances using high-risk bodily enhancement techniques. When Wolfgang challenges the complacency of the S-rank establishment, Hee-yeon confronts him in a duel of raw power. Suffering an overwhelming defeat, she is forced to reexamine her reliance on self-destructive skills, ultimately adopting Wolfgang's harsh advice to refine her physical foundation. Powers: Giant Scythe Arts: Sweeping, broad-range mana cleaves capable of bisecting boss-tier monsters and clearing entire swarms of high-tier fiends. Overdrive: An S-rank physical boost technique that forcibly burns internal mana circuits to multiply kinetic speed and slashing power, previously fatal to her long-term vascular health until corrected by Wolfgang.

The young spear prodigy and heiress of the martial Blue Dragon Clan. Dignified, disciplined, and deeply devoted to her family's martial legacy, Yun-ah's world shatters when high-tier demon lord Astaroth launches an assault on South Korea, leading to her father's brutal battlefield death. Awakening to the celestial constellation of the "Spearman of the Blue Rose" (Joan of Arc), she suppresses her grief to take up the mantle of clan leadership. Recognizing Wolfgang's ancient authority, she aligns herself with his defense force during the Red Moon outbreak. Powers: Blue Rose Spear Mastery: Piercing thrusts empowered by sacred, purifying blue flames. Constellation Stigma (Joan of Arc): Grants battlefield morale surges, unyielding willpower against demonic terror, and sacred anti-demonic piercing thrusts.

An ancient, high-ranking shadow demon from the abyssal depths of Underhell. Umbrax shares an ancient, bitter history with Wolfgang, dating back to the First Holy War. Cunning, sadistic, and patient, Umbrax operates through corrupted human surrogates and occult rituals, exploiting the greed of modern corporate figures to anchor his soul onto Earth. He regards humanity as livestock and modern hunters as frail, pale imitations of the ancient warriors who once defeated his kind. Powers: Abyssal Shadow Manipulation: Can travel through, merge with, and animate shadows into lethal piercing spikes, tendrils, and impenetrable defensive domes. Petrifying Hexes: Ancient curses capable of calcifying mortal flesh into brittle stone upon physical or magical contact. Demonic Transmutation: Corrupting mortal souls to create demonic thralls and biological terror-beasts.

An unscrupulous corporate titan and high-ranking industrialist who secretly trades human lives for longevity and demonic power. Taegwan views hunters, orphans, and lower-tier citizens as disposable capital. His thirst for power culminates in orchestrating a mass-casualty occult blood ritual, sacrificing his own humanity to serve as the physical vessel for the descending Lord of Darkness. Powers: Demonic Possession Vessel: Enriched dark mana pools, bodily mutation into an armored fiend, toxic miasma emission, and corporate-scale necromantic occult arrays.

Twin calamity-tier demon lords who spearhead the multi-city descent from Underhell across Seoul, Daejeon, and Paju. Vulcalas manifests as a subterranean volcanic brute devouring urban infrastructure, while Astaroth is a calculating, aerial demon of slaughter responsible for the annihilation of elite hunter squads and the death of S-rank patriarch Go Seong-yong. Powers: Astaroth: Supersonic flight, razor-sharp wing blades, dark celestial fire, and soul-reaping scythe-strikes. Vulcalas: Magmatic armor, tectonic shockwaves, localized seismic rifts, and molten-metal breath attacks.

The revered patriarch of the Blue Dragon Clan and one of South Korea's cornerstone S-rank vanguard hunters. Steadfast, paternal, and fiercely protective of civilians, Seong-yong embodies the peak of classical Korean spearmanship. When Astaroth descends during the synchronized urban incursion, Seong-yong holds the line alone against the demon lord, sacrificing his life in a blaze of glory to buy evacuation time for his daughter and fellow citizens.
