Formerly the world-renowned Rank 1 player known as "God Ji-Nu" who conquered the 100th floor of Battle of Summoners, Baek Jinwoo fell into a three-year coma as the game world merged with reality. Waking up to an impoverished family and an altered modern society, Jinwoo approaches his second awakening with ruthless calculation, calm pragmatism, and total mastery over game mechanics. He transitions from a secretive strategist protecting his family to an undisputed sovereign who openly dismantles institutional corruption. Powers: Commands an unprecedented roster of EX-rank summons. Possesses encyclopedic dungeon knowledge, flawless tactical micro-management, and high-tier mana synchronization via the "Link" system, enabling his summons to execute peak abilities without delay.

A razor-sharp, ambitious third-generation chaebol heiress of the Daesung Group. Recognizing Jinwoo’s peerless value long before the public catches on, she partners with him to found Yubaek Agency. Ji-ah possesses keen commercial acumen and elite organizational leadership, managing real estate acquisitions, contract logistics, and PR management while keeping Jinwoo's tactical secrets locked down. Powers: High-level corporate networking, financial monopolization strategies, high-tier resource management, and strategic operational oversight.

Jinwoo’s dedicated younger sister who sacrificed her own safety to work as a low-level rune farmer to pay medical bills during his three-year coma. Fiercely devoted to her family, she assumes the role of Director at Yubaek Agency, handling the direct trading and liquidation of legendary dungeon drops. Powers: Market intuition, player trade facilitation, inventory administration, and low-tier rune harvesting knowledge.

An EX-rank Wind Fairy summon who was previously trapped within systemic code bugs until Jinwoo freed and re-summoned her. Cheerful, fiercely loyal, and swift, she acts as Jinwoo's scout, vanguard, and primary aerial asset during high-speed dungeon runs. Powers: High-velocity aerial maneuverability, sonic wind blasts, team-wide acceleration buffs, and sensory scouting; fully augmented with supreme Light Speed runes.

An EX-rank Dragon Mage summon harboring an unstable, immense draconic core. Initially timid and hindered by psychological barriers regarding her destructive output, she flourishes under Jinwoo's tactical guidance and Hungyo's austere drills, evolving into a catastrophic battlefield artillery unit. Powers: Explosive Dragon Secret Arts, catastrophic draconic elemental breath, wide-area annihilation spells, and direct Link-state mana amplification.

An EX-rank veteran tactical instructor summon who values absolute discipline, mental fortitude, and battlefield precision. He acts as the military drill sergeant for Jinwoo's growing army of summons, whipping raw talents like Pokryong into battle-hardened elites while anchoring the frontline. Powers: Master-level close-quarters combat, military-grade defensive formations, summon mental conditioning, and frontline crowd control.

A high-ranking examiner and principled official within Player HQ. After witnessing Jinwoo's calculated neutralizing of a Syndicate terror attack and his record-shattering registration exam, Chang-seok stakes his institutional reputation on sponsoring Jinwoo's ascent against corrupt higher-ups. Powers: Senior bureaucratic authority, national tournament administration, security intelligence access, and official regulatory clearance.

A corrupt, self-serving Player HQ commissioner driven by political vanity and an intense personal grudge against Park Chang-seok. Unwilling to see Chang-seok's protégé succeed, he abuses his administrative authority to rig national tournament brackets against Jinwoo. Powers: Political corruption, tournament bracket manipulation, bureaucratic leverage over veteran player rosters.
