Illich

Illich is a former Russian military officer whose command ability earns obedience in both Sungjin's failed timeline and Franz's current Frostplains party. The two contexts must remain distinct: memories show him as a strict final-group commander, while his current incarnation explicitly admits arranging teammates' deaths for a larger reward share before fighting Franz Hosenfeld. (Chapters 117 and 122–133)

Appearance

Illich is a cold-eyed fighter equipped for frontline command with an axe, a lion-emblem shield, and a helmet capable of checking distant conditions. During his current-timeline fight with Franz, he also wears a dark stealth mantle. His controlled expression and economical movements support the professional impression he makes on new teammates, although that composure breaks when Sungjin's overwhelming statistics remove his expectation of victory. (Chapters 122–125 and 132–133)

Personality

Illich values order, efficiency, and obedience to a predetermined plan. In the failed timeline he rebukes improvisation, reacts angrily when protective magic does not follow the assigned formation, and directs teammates with the confidence of an experienced officer. This rigidity can stabilize a group, but it also creates friction when rapidly changing combat requires individual judgment, particularly in his exchanges with Mustafa. (Chapter 117)

The current-timeline Illich uses the same discipline more cynically. He studies weather, equipment, injuries, statistics, and emotional reactions; speaks just enough to maintain authority; and changes from rescue to calculated exposure once he believes teammates have served their purpose. His motives in that raid are not inferred from nationality, military background, or later memories: he directly tells Franz that he wants weak Hunters removed before rewards are divided and prefers manipulating them into death so the Operator will not mark him as a troll. (Chapters 122–128)

Biography

Commander in the failed timeline

In Sungjin's memory of humanity's final ten, Illich shares command responsibility with Hildebrandt and helps arrange the formation for the Demon King's Castle. He marks magical threats, assigns protective roles, and expects each Hunter to perform the agreed task. When Edward and Mustafa shield exposed attackers instead of the designated tanks, Illich condemns the deviation and mocks Mustafa's faith, revealing both the tactical priority he places on predictable command and the hostility that makes cooperation with him increasingly brittle. (Chapter 117)

Sungjin remembers Illich as skilled and capable of leadership, but not as a suitable foundation for a second final group. Before meeting the current Illich, he already rejects recruiting his former commander because anger and inflexibility would compete with the coalition's need for adaptive trust. That judgment is limited to temperament at first: the failed-timeline scene does not establish how Illich reached the final ten, and it does not by itself prove that the past incarnation committed the same concealed sacrifices later admitted in the Frostplains. (Chapters 117–118)

Ever Dream later revisits and varies that history. In the recorded failed timeline, Edward's surprise spell strikes Illich from behind and lets the Demon King decapitate him. In an alternate run, Illich again reaches a final group, argues for challenging Aizen because the remaining Hunters need greater strength, and dies trying to hold the hidden boss. These visions confirm his recurring command role and combat courage, while leaving the relationship between alternate histories and his current-timeline trolling unresolved rather than supplying a universal motive. (Chapters 167–168 and 171)

The concealed troll

In the current timeline, Illich enters the Kariharan Frostplains under the title Frozen Heart. His weather sense, quick orders, axe-and-shield skill, and willingness to block a Yeti blow win Franz's admiration; Franz even considers recommending him as a Chosen One. Illich questions Franz about that title and studies the party closely, but he continues to present himself as a terse, responsible commander through the Ice Witch battle, rescuing a frozen teammate and helping complete the main objective without incident. (Chapters 122–124)

His conduct changes during the Human Abomination hidden fight. Illich gives plausible orders that expose injured or weaker Hunters to the boss, withholds rescue, and preserves Franz long enough to help finish the battle. Afterward he uses Frozen Heart to inspect Franz's extraordinary bonus statistics and openly explains what he did: the dead had “outlived their usefulness,” fewer survivors meant more reward for him, and inducing others to die or attack first avoided both the troll aura and its penalty. These are Illich's own stated reasons; the narrative does not require an invented grievance or hidden ideology to explain the betrayal. (Chapters 127–128)

Franz attacks despite knowing the system will mark him as the troll, and Illich's Phantom Edge gradually numbs him toward paralysis. When Sungjin answers the delayed request for help, Illich checks the newcomer with Frozen Heart, recognizes the statistical gap, and flees under Shadow Walk before attempting an ambush. Defeated, he claims self-defense and offers to replace Franz as a stronger Chosen One, then makes a final concealed-dagger lunge after Sungjin refuses. Franz interrupts the strike, and Sungjin beheads Illich, confirming that tactical excellence without loyalty has no place in the alliance he is building. (Chapters 129–133)

Relationships

• Franz Hosenfeld: Illich first appears to Franz as the ideal veteran commander, and that earned trust makes his hidden-boss orders effective. Franz's admiration turns to moral outrage once Illich admits engineering the others' deaths; their duel contrasts Franz's impulsive but genuine concern for teammates with Illich's deliberate exploitation of that concern. (Chapters 122–133)
• Sungjin: Sungjin remembers Illich as a capable former teammate yet excludes him from recruitment because of his rigidity even before learning he is a concealed troll. Their current encounter ends that residual respect: Sungjin acknowledges Illich's strength and intelligence but rejects his offer because he would endanger the team. (Chapters 117–118 and 130–133)
• Mustafa: In the failed timeline, Mustafa's decision to shield exposed attackers rather than the assigned tanks draws Illich's anger. Illich turns a tactical disagreement into a disparaging comment about Mustafa's faith, demonstrating why his command style damages cohesion even when the underlying formation concern is real. (Chapter 117)
• Edward: Edward fights within the same failed-timeline formation and is assigned a protected role by its commanders. When Edward turns on the party, his first decisive spell hits Illich from behind, creating the opening for the Demon King to kill him; later alternate history again places both men in a final group. (Chapters 117, 167–168, and 171)

Skills and abilities

Tactical command and analysis. Illich rapidly organizes strangers, establishes attack order, reads blizzard intensity, tracks injuries, and adjusts formations around enemy patterns. His authority and terse confidence make others obey. The same skill becomes dangerous when the objective changes from protecting the group to manipulating it, because his harmful orders remain believable until several consequences have already accumulated. (Chapters 117 and 122–128)

Axe-and-shield combat. Illich combines efficient axe strikes with strong shield defense, kills the Ice Witch, withstands attacks that threaten ordinary Hunters, and remains dangerous against the Chosen-enhanced Franz. His style is direct and optimized rather than elaborate. That efficiency lets him read and answer conventional motions, but it fares poorly against Sungjin's superior statistics, dual angles, anti-magic weapon, and accelerating Frenzy. (Chapters 122–125 and 129–133)

Frozen Heart. The title lets Illich inspect another Hunter's statistics and equipment. He uses it to discover the scale of Franz's Chosen bonus, assess Sungjin, decide that escape is preferable to direct combat, and infer the connection between Chooser and Chosen One. It provides information rather than victory, and Illich's later attempt to misrepresent when and why he inspected Franz exposes his deception. (Chapters 127–128 and 132–133)

Phantom Edge. Illich's axe projects freezing, partly incorporeal edges that can pass through a conventional block and numb the struck limb. Repeated exposure spreads the cold toward paralysis, letting him erode Franz's ability to stand and wield his greatsword. Fire counters the accumulation, and Sungjin's Goat's Fire protection prevents the freezing effect from deciding their fight. (Chapters 129–132)

Shadow Walk and ambush. Illich's dark mantle grants invisibility and supports a sudden aerial axe strike after he retreats from Sungjin. The concealment does not erase physical traces: footprints remain visible in the Frostplains snow, allowing Sungjin and Besgoro to follow him. Once the ambush fails, Illich cannot turn invisibility into a sustained advantage against the faster opponent. (Chapter 132)

Equipment

• Tetracard – Enraged Lion: Illich's lion-emblem shield supplies extremely high defense, faster attacks, and Shield of God for temporary magic immunity. It survives blows from Sungjin's legendary swords and is later taken after Illich's death, becoming evidence that his defense rested on exceptional equipment as well as skill. (Chapters 122–133)
• Phantom Edge axe: The axe produces freezing spectral edges that threaten targets through ordinary blocks. Illich uses it to impair Franz and briefly numb Sungjin's hand, but loses it when Sungjin expels a captured Gust and throws the weapon beyond his reach. (Chapters 129–132)
• Rubin and L'vain mantle: The dark mantle enables Shadow Walk, hiding Illich during escape and ambush. Its invisibility conceals his body but not footprints or disturbances in the environment, a limitation that proves decisive on snow-covered ground. (Chapters 132–133)
• Clairvoyance helmet: Illich's helmet supports long-distance inspection during the Frostplains raid, complementing the situational awareness expected of a commander. The corpus gives less detail about its range and mechanics than it does for Frozen Heart or Shadow Walk. (Chapters 125–126)
