Yi Yeonjun

Yi Yeonjun is the founder and former boss of the Chameleon Troupe. Trained in a mercenary's outlook by Vast Expanse, he builds the original organization with Bell and turns talented children into possessions whose dependence he can control. His most consequential creation is Yi Byul's devotion: he destroys her family life, takes the place of her father, and leaves her believing that Bell murdered him. (Chapters 259, 293, 314, and 336)

After recovering from injuries that kept him hidden for years, Yi Yeonjun pursues Kim Hajin and tries to position himself as Baal's next incarnation body. He remains a separate human from both Bell, Baal's existing host, and Baal himself. His attempt fails, and learning that his world originated as a novel strips his possessions of meaning. He dies when Yi Byul stops his final effort to destroy Hajin inside a collapsing barrier. (Chapters 293, 335–337, 342–344, and 359–360)

Biography

Founding the original Chameleon Troupe

Yi Yeonjun studies under Vast Expanse, who teaches him the mindset of a mercenary. He later passes that outlook to Yi Byul, although she eventually stresses that she is not the same leader he was. Bell's memories establish that Yi Yeonjun caught Baal's attention and that Bell, already serving as Baal's host, met him and formed the original Chameleon Troupe with him. Yi Byul, Jain, and Kaita became part of the family built around those two men. (Chapters 259 and 336)

As boss, Yi Yeonjun leads a version of the Chameleon Troupe described as markedly more cruel and inhumane than its successor. He is its leader during the Kwang-Oh Incident, and Yi Byul later reforms the organization believing that she must carry out his will and avenge his supposed murder. That legacy makes his influence persist through the new Troupe's killings and thefts even while he is officially dead and physically absent. (Chapters 302, 362, and 365)

Manufacturing Yi Byul's dependence

Yi Yeonjun identifies Yi Byul's exceptional potential and decides that he wants to own her. He brainwashes her formerly benevolent parents, persuading them that their daughter's dark power is a curse, and ultimately orders them to kill her. Yi Byul kills them to survive, after which Yi Yeonjun presents himself as her rescuer and assumes the role of her father. The salvation on which her loyalty rests is therefore a crisis he deliberately manufactured. (Chapters 293 and 313–314)

The recorded past also changes Kaita's understanding of his own recruitment. After watching Yi Yeonjun engineer Yi Byul's suffering, Kaita questions whether the drugging and violence that shaped his childhood were similarly arranged. The record proves the scheme against Yi Byul, not Kaita's suspicion, but it is enough for Kaita to reject the man he considered his savior and help kill the recorded version of him. Yi Yeonjun's possessiveness thus fractures the family he claimed to build. (Chapter 314)

Recovery and pursuit of Kim Hajin

Yi Yeonjun survives the destruction of his body by remaining asleep until he is willing to awaken. When Bell meets him in the underwater sanctuary, he has been conscious for only three months after a much longer sleep, still limps, and admits that thinking became difficult during the prolonged recovery. He nevertheless resumes planning immediately, first intending to recover further and then pursue Chae Joochul, the man Bell identifies as having actually destroyed him. (Chapter 293)

His avarice soon drives him into the Orden campaign, where he persuades Bell to travel to Africa and plans to seize Orden's valuable corpse after the Monster King's death. He then reunites with Yi Byul and tries to turn her against Hajin by falsely invoking Bell's supposed betrayal. When that attempt fails, Hajin and Spartan follow him through France; he later captures Hajin's Observer and uses it to arrange a direct confrontation rather than tolerate continued surveillance. (Chapters 299, 302–305, 311, and 333)

Seeking Baal's incarnation

Bell warns that Yi Yeonjun intends to kill Hajin, while Jin Sahyuk helps identify the larger design behind that pursuit. When Bell dies and Baal descends, the devil will require a new incarnation body; Hajin confronts Yi Yeonjun with the conclusion that he wants that position, and Yi Yeonjun answers by attacking rather than denying it. Bell's own memories keep the roles distinct: Bell is Baal's host, Baal is the transcendent devil, and Yi Yeonjun is the separate human whose greed drew Baal's attention. (Chapters 302, 335–336)

The plan brings Yi Yeonjun into Baal's castle after Bell's death, but not as Baal himself. He receives knowledge from Baal that Bell had carried, including the claim that their world originated as a novel, and relays it to Jin Sahyuk. The revelation empties his formerly acquisitive gaze and leaves him unable to find value in the world he wanted to possess. Baal responds with fury and a resolve to destroy; Yi Yeonjun instead admits that he has lost confidence in living. (Chapters 337 and 342–344)

Final barrier and death

Yi Yeonjun seeks Hajin inside Baal's larger barrier and uses Yi Byul's name only to draw attention before asking Hajin about the novel. When Hajin rejects his conclusion that the world and its people remain mere fiction, Yi Yeonjun creates a private barrier, attacks with psychokinesis, and tries to crush him within the changing space. Chae Nayun's arrival prevents the immediate killing, but Yi Yeonjun keeps fighting even after her sword strikes leave him bloodied. (Chapters 355–358)

Unable to defeat Hajin and Chae Nayun conventionally, Yi Yeonjun decides to detonate his own barrier and kill everyone inside, accepting his own death if it gives Hajin's death meaning. Yi Byul interrupts the collapse by piercing his stomach with a black blade. She carries away his corpse, later buries him in Pandemonium, and disbands the Chameleon Troupe that she had rebuilt for his sake. Months later she still visits his tombstone, but her new charitable work marks a life no longer organized around fulfilling his wish. (Chapters 359–360, 362, 365, and 370)

Appearance and personality

Yi Yeonjun is a man with well-defined facial features, sharp brown eyes, and dimples that appear when he smiles. His firm expression and rigid, stern manner of speaking become traits that Yi Byul imitates. After his long sleep, his hair has grown long enough to aid a disguise, and his damaged body leaves him walking with a limp. Later battles cost him an arm and leave him bloodied without removing the severe intensity of his gaze. (Chapters 293, 301, 321, 337, and 358)

His defining trait is avarice directed at people as readily as objects. Bell describes him as someone unable to rest until he obtains whatever interests him, while Yi Yeonjun himself admits that he broke Yi Byul because broken people are easier to own. His pride in her resembles an owner admiring a weapon, not a parent valuing a child. Once the novel revelation devalues everything outside himself, that dependence on possession becomes an existential weakness and leaves his eyes vacant. (Chapters 293, 299, 336, and 342–344)

Gifts and abilities

Temperature manipulation

Yi Yeonjun can freely alter the temperature of his magic power. His white magic power branches outward or becomes tentacle-like strands, alternating between extreme heat and cold rapidly enough to rust Hajin's gun, break his armor, shatter Aether, melt the ground, and evaporate matter. He can also fire concentrated heated magic power as a beam. The corpus describes this effect as his Gift but does not provide it with a formal proper name. (Chapters 335–336)

Temperature control is formidable defense as well as offense, but it does not make Yi Yeonjun untouchable. Hajin judges that a distant surprise attack would give him a better chance than a direct fight, and Yi Yeonjun's defenses withstand Hajin's varied close-range arsenal. They do not prevent Boss's shadows from piercing him, Chae Nayun's surprise strike from covering him in blood, or the combined pressure that forces him toward a self-destructive last resort. (Chapters 336 and 356–359)

Psychokinesis and barriers

Yi Yeonjun demonstrates powerful psychokinesis by choking Hajin at a distance, crushing his finger, jamming a gun's trigger, and forming an invisible wall that stops Chae Nayun's sword magic. He also creates a sealed barrier within Baal's barrier and can distort or shrink its space around its occupants. These effects are directly shown, but the corpus does not establish whether they are separate Gifts, applications of one ability, or learned magic. (Chapters 357 and 359)

His control has practical limits. Aether can resist the first contortions of his private barrier, Chae Nayun can push its contracting walls back, and dividing his attention gives Hajin openings to fire. Detonating the space also requires the remainder of Yi Yeonjun's magic power and would kill him along with his targets. Yi Byul's attack interrupts that detonation, after which removing his body causes the barrier to dissolve. (Chapters 357 and 359–360)

Combat judgment and recovery

Yi Yeonjun is dangerous enough that Hajin avoids careless eye contact, Bell explicitly warns others about him, and multiple exceptional fighters are needed to overpower his recorded counterpart. He detects the Observer following him, exploits the mechanical weakness of Hajin's gun, and combines environmental control with rapid temperature changes. His recovery is exceptional but not immediate: a ruined body requires an extremely long sleep, and even three months after awakening he remains incomplete and walks with a limp. (Chapters 293, 302, 305, 314, 333, and 357)

Power progression

Relationships

Yi Byul

Yi Byul sees Yi Yeonjun as a father because he takes her in after she kills her parents, but he secretly engineered the danger from which he appeared to save her. He takes pride in her power as a possession, leaves her successor Troupe organized around his supposed death, and later tries to use her grief against Hajin. She cannot erase two decades of attachment immediately, yet ultimately rejects his ownership by killing him, burying him, and choosing atonement over his unfinished ambitions. (Chapters 293, 302, 313–314, 356, 359–360, and 362–370)

Bell

Bell is Yi Yeonjun's longtime comrade and co-founder of the original Chameleon Troupe. He hides Yi Yeonjun during recovery, accompanies his attempt to claim Orden's corpse, communicates with him secretly, and helps plan the conflict that could make Yi Byul turn on Hajin. Bell also recognizes Yi Yeonjun as a monster whose attachment to people is possessive. Despite their closeness, Bell remains Baal's incarnation body and is never another identity or appearance of Yi Yeonjun. (Chapters 293, 299, 302–305, and 336)

Baal

Baal is the devil whose attention Yi Yeonjun attracts and whose next incarnation body he seeks to become. Baal's memories give Yi Yeonjun knowledge of the world's origin, and the two share the resulting crisis without becoming the same being: Baal answers with destructive rage, while Yi Yeonjun loses the confidence to continue living. Bell is Baal's earlier host, and the humanoid or transcendent forms Baal displays after Bell's death belong to Baal, not to Yi Yeonjun. (Chapters 335–337 and 342–344)

Kim Hajin

Yi Yeonjun regards Hajin first as a threat to his hold over Yi Byul and then as the author responsible for the world in which he lives. He lies to Yi Byul about Hajin's alliance with Bell, captures Hajin's Observer, and attacks him with temperature-changing magic. After learning the truth carried through Baal, he asks Hajin whether he is a god and finally decides that killing the one life he considers real would give meaning to his own death. (Chapters 302–305, 333, 335–336, and 356–359)

Items

Observer

Yi Yeonjun captures one of Kim Hajin's Observers after detecting that it is following him. He holds the small surveillance construct, communicates with Hajin through its shared vision, and keeps it until directing Hajin to their meeting place. The Observer is Hajin's creation rather than Yi Yeonjun's permanent equipment, and the scene demonstrates Yi Yeonjun's awareness and counter-surveillance more than ownership of a personal artifact. (Chapters 333–334)
