Prologue[]

Spoilers
In the northern capital of Arcs Styrie, within the resplendent throne room of Roa Gracia’s royal palace, the king—embodiment of the nation’s militaristic and archaic values—summons his son, Prince Viktor Idinarohk. Despite its northern chill and austere landscape, United Kingdom of Roa Gracia prospers thanks to its fertile soil, powerful rivers, and rich mineral resources. Before the throne, Prince Viktor Idinarohk, the king’s youngest son and commander of the southern front, stood with quiet resolve. Though wrapped in the formal setting of a royal court, the conversation between Prince Viktor and the king carries a casual, almost familial tone beneath the surface. They discuss the Eighty-Sixth Strike Package—a foreign elite unit battling the Legion. While the unit has struggled, its ability to draw out new enemy types has made it a valuable strategic asset. The king informs Viktor that the United Kingdom will form an alliance with the Federacy, exchanging technology and dispatching personnel to support the unit. As part of this, Viktor is assigned to join the Eighty-Sixth Strike Package. He accepts without hesitation, requesting only to bring his personal unit, the Songbirds. Prince Viktor returned wearing his school uniform, carrying his schoolbag despite the chamberlain’s protests. This casualness isn’t carelessness, but a symbol that royal formalities are secondary to the real power shared between Viktor and his father, the king. The prime minister expresses concerns about Prince Viktor’s absence affecting defense, but Viktor dismisses them, stressing that the army shouldn't depend on one person. Prince Boris objects, blaming Viktor for the war, but the king silences him. Viktor, uninterested in power, requests to leave for schoolwork. The king allows it, and Viktor departs, overhearing a harsh comment.


Viktor, arriving in his brother Zafar's chamber, is greeted warmly with tea and a discussion about the worsening war. Zafar, the crown prince, explains that the situation is dire, with the kingdom struggling to maintain its defenses. They discuss the United Kingdom’s cooperation with the Federacy, focusing on technology exchange and the involvement of the Eighty-Sixth Strike Package, which Viktor's elite unit, the Songbirds, is a part of. Viktor expresses his cynicism about the political motivations behind the alliance, acknowledging that the Federacy's request is likely more about desperate hope than genuine cooperation. The conversation shifts to the Merciless Queen, with Zafar suggesting that the Federacy’s desire for information about her could be crucial in ending the conflict. Viktor, however, remains skeptical, reflecting on his own role in the war and the use of the Eighty-Six, whom he sees as expendable tools in a ruthless system. As they discuss the harsh realities of war and the expendability of soldiers, Viktor muses on his own fate, recognizing that, much like the Eighty-Six, he is viewed by others as a monster to be used and discarded.

Chapter 1[]

Spoilers
Rito Oriya, a young Processor, is unexpectedly assigned to the Spearhead Squadron, a unit typically reserved for veterans nearing the end of their service and expected to die. His reassignment coincides with a catastrophic large-scale offensive by the Legion, during which the Republic’s last stronghold falls. As chaos erupts, Rito and 22 other surviving Eighty-Six are urged to flee by the base’s chief mechanic, Lev Aldrecht, who chooses to stay behind with the rest of the maintenance crew. They sacrifice themselves to buy time for the young soldiers, hoping to atone for years of silently watching children be sent to die. Rito and his comrades escape on their Juggernauts and seek refuge in the southern sector, where they find temporary shelter with the Razor Edge defensive unit. However, the situation remains dire, and the unit is quickly overwhelmed by Legion forces. Amidst the confusion, reinforcements arrive from the neighboring nation of Giad, and Rito spots an advanced Feldreß—possibly piloted by his former squad leader, Shin Nouzen, whom he believed to be dead. When the two reunite, Rito informs Shin of Aldrecht’s death, though he withholds the man’s final words. As they travel by train to their next assignment, Rito reflects on his fear of death and the trauma of watching others die—a fear he feels Shin can no longer comprehend.


Shin and Lena are both struggling with the aftermath of a painful argument that created emotional distance between them. Lena, feeling guilty for accusing the Eighty-Six of still being trapped by their past, is overwhelmed with shame and avoids confronting Shin. Meanwhile, Shin is confused and hurt by Lena’s words but doesn’t fully understand why they affected him so deeply, so he retreats into silence. Though they continue working together, their relationship is now strained by unspoken tension and unresolved feelings. The unit is currently in a high-speed military transport running along the western intercountry railway, specifically the Eaglefrost route. It passes through the Dragon Corpse Tunnel, the longest railway tunnel in the world, which connects the former Empire of Giad with the United Kingdom of Roa Gracia. Their destination is Rogvolod City, the southernmost civilian-populated city in the United Kingdom, which lies at the foot of the Dragon Corpse mountain range. From there, they are headed to the Revich Citadel Base, where the Eighty-Sixth Strike Package will prepare for their next mission against the Legion. The next mission in the United Kingdom consists of capturing the Legion commander unit known as the Merciless Queen. The Spearhead Squadron and Lena meet with Prince Viktor “Vika” Idinarohk, an Esper and military prodigy, who reveals the nation's dire state: the Legion's Eintagsfliege units have unnaturally extended winter, threatening agriculture and survival. Vika introduces them to Lerche, a humanoid artificial soldier called a Sirin, shocking the group when she removes her own head to reveal she is powered by a digitized reproduction of a human brain. This deeply disturbs Shin and Lena, who sees the Sirins as a violation of the boundary between life and death, echoing his trauma from the Legion’s use of human consciousness.

Later, Prince Viktor brings Shin deep into an ice-bound mausoleum to reveal the dark truth behind his mother’s remains. The royal family of the United Kingdom, as part of their tradition, preserves the remains of their ancestors in this frozen crypt, where the bodies of deceased family members are carefully enshrined in ice coffins, kept intact with advanced preservation techniques. Vika explains how his mother’s brain was removed and became the basis for the Legion, an artificial intelligence that would later bring devastation to humanity. Vika reveals his obsessive, childlike desire to resurrect his mother, driven by a yearning for a maternal connection he never had. His delusions of control and twisted reasoning become evident as he admits to desecrating her remains in his failed attempt to restore her. Despite the horror of his actions, he shows no remorse, convinced that his longing to reunite with her justifies any means. This obsession ultimately cost him his royal succession, but Vika’s fixation didn’t end there. After the failed resurrection, he uploaded his research to the public network, unaware of the global ramifications it would cause. Vika believed that his failure was due to his youth, lack of knowledge, or a flaw in his theory. At the time, he viewed the world with naive optimism, thinking that with the right method, any desired result could be achieved. His crude, immature writings, despite their simplicity, attracted the attention of Major Zelene Birkenbaum, a military researcher working on autonomous weapons for the Empire. She saw potential in his work, which would later evolve into the creation of the Legion. Vika never foresaw that the very weapons he helped inspire would be turned against him, triggering a devastating war. By the time the Empire declared war, Zelene had already died, leaving Vika to confront the unintended consequences of his actions—the destruction of other nations and the suffering of countless families. Vika admits to indirectly causing the destruction of Shin's homeland and family but is met with Shin's indifference, as he no longer feels the loss. Vika desperately seeks confirmation about his mother's fate, but Shin, with his ability to hear the dead, tells him she is gone, leaving Vika resigned to the finality of death. As Vika presses Shin about his own emotional detachment, Shin reveals his belief that the dead can never interact with the living and has no desire to reconnect with his past. Vika hints that Shin may be suppressing a deeper wound but chooses not to push further, acknowledging it's not his place to comment.

Chapter 2[]

Spoilers

The Spearhead Squadron is shown around the Revich Observation Base, a towering fortress built into the United Kingdom's southern front’s mountains. Designed for impact observation, it's strategically important and largely impregnable due to its rugged geography and reinforced defenses. This base will serve as the temporary headquarters for the Federacy's Eighty-Sixth Strike Package. Lena and her unit meet the Sirins—mechanical, human-like female soldiers created from the brain patterns of the dead. Though designed for emotional suppression and battlefield efficiency, their human appearance raises ethical questions. Lena struggles with viewing them as mere machines, especially after noticing their personalities. Vika, the prince and southern front commander, explains their origins with a mix of pride and emotional distance. The discussion reminds Lena of Shin’s brother Rei, a human-turned-Legion, deepening her guilt over dehumanizing the Sirins. While at the Revich Citadel Base's underground cafeteria Shine and the others notice the seated class and racial divisions within the United Kingdom. Soldiers are divided by eye color and ethnicity, with Viola (those of noble birth, identified by their violet eyes) holding the highest social status. They display open disdain for serf soldiers, who are of lower birth and belong to other racial or ethnic groups, as well as foreign allies like the Eighty-Six, despite the latter's noble or officer status in their home countries.Later on, Lena heads to Vika's private quarters to ask about the psychological toll of extrasensory powers like Shin’s ability to hear the Legion. Vika dismisses the idea of lasting harm but warns Lena not to patronize Shin by assuming he’s too damaged to choose for himself. He critiques her idealism, comparing her to a snow goddess—beautiful, pure, and untouched by suffering, yet cold, distant, and fundamentally incapable of understanding the weight others bear. Her desire to shield Shin from harm, while well-intentioned, is framed as arrogant and presumptive, as if she alone knows what’s best for him. Moving past the conversation Vika gives Lena a device called the Cicada, a choker-like Thought-Support Device developed to reduce the mental and neurological strain caused by Para-RAID Resonance, especially in high-load scenarios like commanding multiple units. As Vika is aware that Lena has been over exerting herself by connecting herself with a large amount of people during missions. Lena tries it on in another room and leaves out of embarrassment after trying it on.

During the operational briefing, a high-stakes joint mission is outlined targeting the Dragon Fang Mountain, a key Legion manufacturing stronghold. The Strike Package is tasked with leading the primary infiltration, while the United Kingdom’s 1st Armored Corps launches a diversion to draw Legion forces away. The mission’s central goal is the capture of a Legion command unit, codenamed the Merciless Queen—a rare white Ameise believed to contain intelligence vital to ending the war. While conducting recon near Dragon Fang Mountain, the Spearhead unit, coordinating with United Kingdom forces, navigated snow-hardened terrain alongside modified Juggernauts and Barushka Matushkas. As the mechanical Sirins carry out scouting duties ahead, the Eighty-Six observe them with unease. Though human-shaped, Sirins are emotionally vacant constructs built from the brain data of the dead—eerily efficient, yet deeply unsettling. Shin, Kurena, Theo, and the others debate the Sirins’ nature, comparing them to Legion units like Black Sheep or Shepherds. Kurena voices visceral discomfort, likening Sirins to “walking corpses,” while Theo critiques their inhuman behavior and appearance. Shin, haunted by memories of his brother Rei’s transformation into a Legion unit, quietly wrestles with whether Sirins are just machines—or something more. Meanwhile, Lena and Frederica listen in, noting the Eighty-Six's lack of sympathy toward the Sirins, despite their shared experience as expendable tools of war. Frederica posits that the Sirins provoke an essential question: What defines humanity? The encounter, she suggests, might force the Eighty-Six to reflect on their identity, their past, and the future they never thought they'd live to see. After a grim exchange with the coldly artificial Sirin, Lerche, the Spearhead Squadron faces a surprise attack when the Legion deploys a previously unconfirmed artillery-support unit: the Zentaur, an electromagnetic launcher capable of flinging lightweight units like the Ameise and self-propelled mines far behind enemy lines. These units glide in via boosters and deployable wings before dropping into forest clearings, launching a sudden assault on Federation forces. The Spearhead Squadron receives a scheduled message from Lerche, who asks why the Eighty-Six returned to combat after being granted refuge. Kurena fiercely responds that they fight by choice, not out of obligation. The conversation is abruptly cut off when the squadron faces a surprise attack from the Legion, which deploys the previously unconfirmed Zentaur artillery-support unit. The Zentaur uses electromagnetic launchers to propel lightweight units like Ameise and self-propelled mines deep behind enemy lines, where they glide in via boosters and wings before launching a sudden assault on the Federation forces. Despite the ambush, Shin quickly coordinates an efficient defense by predicting the glider trajectories, supported by artillery from the United Kingdom. Vika, a United Kingdom commander, steps in with a large Sirin battalion, including Lerche, to engage the attackers. Their eerily efficient, emotionless combat contrasts with the Eighty-Six’s raw determination. Impressed by the Eighty-Six's combat skills, Vika suggests having them pilot the Alkonosts, revealing that Sirins were designed to be compatible with humans in such scenarios. Lena, curious about Lerche's human-like traits, asks Vika about her origins, but Vika hesitates and deflects, leaving the mystery of Lerche’s true nature unresolved.

On a snowy battlefield, Shin’s Undertaker switches from melee to recon duties, using himself as a decoy to help his squad avoid encirclement. The Alkonosts, engaging the Legion with close combat tactics, sacrifice themselves in attempts to take out enemy forces, prompting concern from Raiden about their expendability. After Shin defeats two Löwe units, he encounters Chaika, a Sirin, who asks him if he would consider enhancing his body to improve combat abilities. Shin is unsettled by her suggestion of abandoning humanity for greater power. Later, Shin rescues Ludmila, a Sirin, who expresses pride in being a tool for the United Kingdom. Anju surveys the battlefield, noting that the situation seems under control and the enemy is likely to retreat. Dustin, the least experienced member of the squad, asks about enemy remnants, and Anju cautions him not to rely too heavily on Shin's abilities, warning of the danger if they lose him, though acknowledging that things have changed since the past. Suddenly, a self-propelled mine detonates, triggering a chain reaction that collapses the battlefield around them. Both Dustin and Anju's Juggernauts plunge downstream, with both of them stumbling toward the lone hunting lodge for warmth and safety. Meanwhile, the rest of the squad, back at base, organizes a search. Frederica, attempting to locate them, fails to provide any useful information, much to the group's frustration. Eventually, they figure out the key to finding their location: the weather and the stars. The team prepares to search for their missing comrades, with Vika cracking jokes to lighten the mood.

Back in the lodge, Anju and Dustin, stranded in a small lodge on the battlefield, share a quiet, intimate moment as they try to stay warm and reflect on their pasts. Anju struggles with her memories, haunted by the loss of her mother and the scars of being driven out to the internment camps as an Eighty-Six. Dustin opens up about his own struggles as an Alba, recalling how he was the only one spared from the internment camps despite being originally from the Empire. Dustin lived in a town as a first-generation immigrant, being the only Alba in his school until the war began. Dustin joined the unit out of guilt and moral responsibility for being unable to stop the cruelty inflicted on the Eighty-Six. As Dustin hands Anju his blanket and glimpses the scar on her back, he responds not with disgust but with quiet empathy, gently urging her to remove it—not for its appearance, but because it looks painful. Dustin shyly but sincerely confesses his feelings to Anju, surprising her with his heartfelt honesty and admiration for her. Though touched, Anju admits she can’t love again, still haunted by the memory of someone she once loved deeply—someone she believes she’d always compare others to. Dustin gently challenges her thinking, telling her it's okay to carry those memories and still find new love and happiness. Their emotionally charged moment is broken when Shin unexpectedly arrives, unintentionally overhearing everything and delivering some comic relief. As Shin helps them with new uniforms, he offers quiet support and gently tells Anju that the one she lost, Daiya, wouldn’t have wanted her to remain trapped in grief. Anju smiles through her tears, acknowledging the truth in his words, but also admitting that she’s not ready to move on just yet.

Shin, usually unshaken by the chaos of battle, hesitates when inviting Lena to the observation tower. A rare sense of nervousness grips him, a mix of anticipation and fear. Despite the cold and harsh surroundings, he manages to ask, and Lena agrees. When they reach the top, the sky is breathtaking, filled with stars that Lena has longed to see. In the First Sector, the constant fog blocked the view, but here, the stars shine brightly. Shin, though accustomed to the sight, feels a new appreciation, perhaps because he’s sharing it with her. As they stand in silence, Lena speaks of the Eighty-Six, freed from their fate but unable to imagine a future beyond war. She believes their kindness, not hatred, prevents them from wishing for more. Shin, lost in thought, struggles with his own inability to see a future for himself. Despite his freedom, the battlefield is all he’s ever known, and he can’t picture life beyond it. Lena, sensing the moment, apologizes for their past argument. Shin remains silent, reflecting on the emotional scars they both carry. These scars have become part of who they are, a reminder of the choice not to let hatred define them. They’ve both endured loss, but together, they’ve formed a bond that transcends their shared pain. Shin hesitates, wanting to tell Lena he dreams of showing her the sea, a peaceful escape from the war. But doubt creeps in. What comes after that? What would it mean? His fear of not being able to fulfill such a wish silences him. Despite Lena’s warmth and understanding, Shin is paralyzed by self-doubt, unsure about what comes after or if such a wish can ever be fulfilled.

Chapter 3[]

Spoilers
As Shin and his unit travel toward Dragon Fang Mountain, he senses something wrong: a strange mechanical howling among the Legion forces. He realizes too late that the Legion have used a feint — the United Kingdom’s diversion was a trap, and now the enemy is launching a surprise assault. Despite Shin's warning about the attack, the Revich Citadel Base is overwhelmed. A high-speed Legion unit, the Phönix, undetected by sensors due to its optic camouflage, infiltrates the base via a glider launched by the Zentaur. The base's surface and most underground sectors were quickly overrun. It bypasses defenses, devastates the base from within, and clears the way for more Legion units to take control of nearly the entire installation. Only the command ward and the eighth underground hangar remained under their control, where the surviving personnel, including Lena, Vika, Federacy soldiers, base personnel and maintenance crew, Handlers, and Feldreß, retreated.


Shin reflects on the unfolding disaster, realizing too late that the Legion’s surprise invasion was made possible by the Phönix—an advanced, lightweight unit capable of stealthy aerial assaults. It was a tactic no one anticipated, as the Legion had never used airborne methods before. Burdened by guilt, Shin feels he should have foreseen it, but Lena, still inside the besieged base, reminds him that anticipating the enemy’s tactics is a commander’s responsibility—not his alone. Vika then briefs the group on the dire state of affairs: the Revich Citadel Base is surrounded and completely cut off from friendly forces, with reinforcements at least five days away. Meanwhile, an armored Legion unit 8,000 strong—including the monstrous Dinosauria and Löwe—is advancing and expected to arrive within a day. Inside the base, roughly 1,000 Legion troops remain active, while the Federacy’s remaining defenders are holding out in only two sections: the command ward and the eighth underground hangar. Despite the overwhelming odds, Vika declares that they have no choice but to hold their ground and prepare for a siege battle.

The Strike Package, consisting mainly of Eighty-Six combatants accustomed to squadron-level operations, was reorganized into fourteen battalions with squadrons as the basic units. Shin acted as the overall commander, with the battalion captains being the most veteran members, including Spearhead squadron officers and Bernholdt, the oldest noncommissioned officer. The Sirins’ representative was Lerche, and on the other side of the Resonance were Lena, Vika, and Raiden. Shin reflected that the delay caused by Anju and Dustin’s recent stranding had worked in their favor, as it postponed their departure and allowed them to disable traps along their retreat path. However, the situation was dire: their main base had fallen, they were isolated in enemy territory, and while friendly reinforcements wouldn't arrive for five days, enemy reinforcements were expected much sooner. Although outnumbered and caught off guard, Shin and his commanders—supported by just 6,000 troops, including Alkonosts—gather to devise a counter-strategy. During the war council, Second Lieutenant Michihi suggests intercepting the incoming Legion reinforcements, but Lena rejects the idea, arguing it would only drain their strength needlessly. She identifies the Legion’s real objective: to seize control of the Revich Citadel Base. Given the circumstances, their only viable course of action is to break the siege from within by retaking the base. Theo challenges the boldness of this plan, prompting Lena to explain why traditional siege tactics—such as starving out the enemy, tunneling, or bombarding—won’t work against the Legion. With no time, no supply lines, and no way to negotiate, only one option remains: a direct frontal assault—scaling a 100-meter cliff and breaching 20-meter-high walls to strike at the enemy-held fortress. In a tense war council, Shin and his team confront the harsh reality of retaking the Revich Citadel Base by scaling a 100-meter cliff under enemy fire—an operation far beyond the typical capabilities of their Juggernauts. With no supplies to support a retreat or regroup with allied forces, retreat is deemed impossible. Understanding the urgency and the need for clarity among their troops, Shin explains the strategic necessity of reclaiming the base rather than abandoning it. The Strike Package is split: half, under Bernholdt's command, will engage in stall tactics to delay the approaching Legion reinforcements, while the rest, including Shin, will lead a direct assault on the base to rescue those trapped inside. Despite the grim odds, they commit to the mission, knowing they must succeed before the command ward is overrun.

Vika agrees to take command inside the citadel, and Lena receives full control over the Sirins for the operation. With the siege battle imminent, both Lena's team inside the Revich Citadel and the Strike Package outside prepare for defense. Lena coordinates operations from inside with the base's command staff and Vanadis’s control crew, while Raiden and others stand by in the hangar—the base’s most vulnerable point. Handlers Resonated with Sirins to direct the defense, and surviving soldiers secured key corridors. From the Federacy capital, Grethe informed them that reinforcements would be sent due to the Legion’s intensifying assault. Shin, inexperienced in siege warfare, passed overall command to Lena and Vika. Vika, despite also lacking direct siege experience, prepared to oversee the fortress defense, equipping older anti-tank rifles suitable for indoor use. Lena realized the Legion also likely lacked siege warfare experience. Most Legion units were formed from assimilated civilians or child soldiers with no formal training—especially from the Republic, which had left many corpses unclaimed. This gave Lena's side an edge in terms of tactical knowledge. Annette and Grethe, speaking from the comfort of Roa Gracia’s royal castle, suspect something is off about the Legion’s ability to track and repeatedly target the Strike Package. Although interception of Para-RAID communications seems unlikely, the precision of the Legion's attacks raises concerns. Grethe suggests a grim possibility: that someone within the Federacy military may be leaking information to the enemy.

Lena prepares for the upcoming siege operation by activating the Cicada—a Thought-Support Device given to her by Vika to help manage the mental strain of Resonating with over a hundred Processors. The device, composed of quasi-nerve fibers, links with her RAID Device and forms a glowing, skin-tight bodysuit that functions as an auxiliary brain. As the silver threads spread across her body, the sensation is strange and intimate, leaving her feeling slightly exposed. Though uncomfortable under her uniform, Lena wears the device to maintain command without risking collapse from overexertion. Lena’s return to the command room in the form-fitting Cicada suit draws awkward reactions from the command team. Vika, apologizing halfheartedly, admits that the device is also used by Lerche but fits her more modest figure better. His comment—and the resulting conversation about Lena’s more pronounced figure—leaves her stunned and embarrassed. The staff avert their eyes, and Marcel pointedly avoids looking at her, fearing Shin’s reaction. To spare her more discomfort, Frederica drapes a large Federacy blazer over Lena’s shoulders. After being disconnected for a while, Lena reconnected to the Resonance, and her unusually curt and flustered tone immediately tipped Shin off that something was wrong, despite her attempts to sound composed. Though she brushed it off, her emotions leaked through the Resonance, prompting Shin to quietly decide to ask Frederica or Marcel about it later.

As snow falls over the darkened landscape, Shin and the Strike Package survey the heavily fortified Revich Citadel from a nearby forest. The citadel, perched atop a massive cliff and reinforced with steel and natural rock, is nearly impervious to bombardment. Open terrain and a lack of cover make a direct assault risky, and attempts to consider alternative entry points—like the northwestern gate—are dismissed due to deadly traps, mines, and concentrated fire zones. Discussions reveal that the fortress is designed to be nearly impenetrable, even containing internal defenses and traps. With no safe way in, the team determines that scaling the cliff is the only option, prompting Vika and Lerche to remind them that the Sirins were created for reconnaissance in such situations. A team of four Alkonosts advanced from the forest to scout the Revich Citadel, maintaining a spread-out formation to avoid enemy fire. As Shin received real-time footage from their cameras, it revealed the daunting structure: a massive cliff crowned with reinforced walls, a dry moat filled with anti-tank spikes, and ice-covered surfaces designed to prevent climbing. Theo proposed a limited-scale climb using wire anchors, but before any action could be taken, Shin sensed incoming Legion activity. A previously unseen Legion unit, resembling a scorpion and equipped with a massive howitzer, emerged from the citadel's defenses. Shin recognized it as a “Skorpion”—a heavy artillery unit not meant for front-line combat. Realizing the threat too late, he warned the Alkonosts to retreat just as the Skorpion unleashed a devastating howitzer volley at them. Lena is shocked to learn that the Legion deployed Skorpion artillery units—normally used for rear support—directly to the front lines. Vika quickly deduces their purpose: to destroy the command ward's internal partitions with their powerful 155 mm howitzers. Despite their vulnerability, the Skorpions were ideal for the mission due to their lightweight, easily launched design. Unlike humans, the Legion showed no concern for unit safety or conventional tactics, acting purely on ruthless efficiency. Realizing they must distract the Skorpions to protect the fortress interior, Lena, despite her fear and guilt, orders the second squadron to advance and keep the cannons occupied, knowing hesitation would only lead to greater losses.

During the intense siege of Revich Citadel, Shin and the Spearhead squadron struggle to push forward against the overwhelming firepower of the Legion. The Skorpion artillery, designed for long-range attacks and ill-suited for close defense, pounds the base from a distance. Shin orders reinforcements to the walls and requests sniping support from Kurena, who tries to find a vantage point beneath the cliff. However, her chosen position is already mined, revealing that the Legion anticipated their movements and set deadly traps along their likely return path. Meanwhile, deep within the underground hangar, Raiden and the Juggernauts hold a desperate line against relentless waves of self-propelled mines and Ameise units. Their defense quickly descends into brutal close-quarters combat, with even injured maintenance crew members forced to join the fray, underscoring the defenders’ dire situation and unity. Back above ground, Shiden and the others anxiously watch for the appearance of the Phönix—a formidable Legion unit that has yet to enter the battle. From the command ward, Vika efficiently directs the defensive lines, expertly coordinating troop deployments to repel attacks and manage the myriad traps laid throughout the key corridors. He warns Lena of the catastrophic consequences should even a single mine breach their defenses. As the weather worsens, a heavy blizzard reduces visibility for both sides. Under this cover, Shin and Theo attempt to scale the fortress wall but are ambushed by hidden self-destructing mines. After sustaining damage, Shin receives orders from Yuuto to disengage and focus on reconnaissance rather than direct combat. When a howitzer disables key cameras and cuts off surveillance, Lena relies on her memorized battlefield knowledge to maintain command. With the Cicada system’s help, Lena reconstructed and maintained this map of the battlefield in her mind and kept giving orders in succession even after the screen came back to life. Suddenly, a mechanical butterfly called an Eintagsfliege suddenly appears in the command post, disrupting communications with its powerful electromagnetic waves and posing a deadly threat. Marcel quickly reacts, knocking it down with his rifle and Vika finishes it off with a precise gunshot. Lena breathes a sigh of relief, grateful to Marcel for saving her life.

A platoon of “Sirins” suddenly lose connection with their Handlers, signifying they were killed after the Eighty-Six used them as bait to draw the enemy’s attack. The Handlers of the United Kingdom viewed the Sirins not just as weapons, but as cherished partners—sometimes like family or loved ones—and felt deep empathy for them, experiencing intense grief and rage at the inhuman tactics and the Eighty-Six who led their partners to death. Despite their grief and resentment, a commanding officer reminded them that the “Sirins” had volunteered for this fate and that hatred was misplaced, as both sides suffered losses trying to protect their commanders and comrades. As the battle continues, despite heavy losses and low ammo, the Legion resists the feint and searches for other ways to breach the citadel walls. Shin grew impatient as their casualties and ammunition dwindled, while the enemy’s reinforcements approached and the citadel’s defenders remained strong. A disobedient platoon attempted a doomed wall climb, suffering heavy losses from machine-gun fire and traps. The Legion used brutal stall tactics—rolling flaming barrels and self-destructing mines down the cliffs—to block the Juggernauts, whose aluminum armor was vulnerable to fire. With fires raging and snow intensifying as sunset neared, Shin realized they couldn’t attack further today and had to wait, despite the worsening situation and rising enemy numbers.

As the sun set and the fighting subsided, a blizzard overtook the battlefield, forcing the Strike Package to halt their advance. With visibility crippled and systems rendered ineffective, the Spearhead squadron retreated into a conifer forest to make camp and tend to their worn-down machines. Lena and Vika debated who should rest first, each concerned for the other’s exhaustion. As the fire trench’s flames died and the snow took dominion over the battlefield, Michihi—a petite, snow-hardened Handler from the northern front—approached Shin with advice on preventing the Juggernauts from freezing. She offered her help with quiet fatigue, and Shin, grateful, urged her to rest. Nearby, Scavengers returned with the wreckage of destroyed Juggernauts and fallen comrades, while medics and maintenance crews worked in grim silence. Inside the transport vehicle, Shin was greeted by Anju’s soft smile, a brief comfort in the bitter cold. The squad reflected on the heavy losses and the unnerving calm of the Sirins—mechanical soldiers who faced death without emotion. Their eerie resilience stirred memories of the Eighty-Six’s own past as expendable fighters. Rito, disturbed and afraid, still chose to fight on, clinging to his identity. Meanwhile, Lena returned to her quarters, where Frederica helped her fold a uniform and urged her to rest and speak with Shin—reminding her that even in war, moments of humanity must be preserved. As the siege drags on and morale wanes, Shin encounters Lerche after a grim debriefing. She offers to take over night watch duties with the Sirins, urging him to rest. Their conversation turns introspective as Lerche reflects on her artificial nature. Though not human, she expresses a quiet sorrow about her existence—created in the image of Lady Lerchenlied, His Highness’s milk sister—yet she is devoid of true identity or memories. Shin, who can hear the voices of the dead, recognizes the same mournful echoes in her as in his fallen comrades. Though he acknowledges that she isn’t truly alive, he can’t bring himself to dismiss her as less than human. Later, Lena contacts Shin, concerned for their well-being. Despite the blizzard and danger, their exchange offers a brief moment of emotional reprieve. However, the mood darkens when Lena urges Shin to retreat and abandon them if necessary. Shin reacts with quiet fury, refusing to obey such a request. To him, leaving her behind would betray the very wish that has kept him going—to share a peaceful future with her. Having already endured the loss of countless comrades, Shin cannot accept the thought of losing Lena too, and he refuses to leave her behind.

Chapter 4[]

Spoilers
Vika reflecting on his past transgression—an attempt to resurrect his mother through dissection, an act that rendered him a monster in the eyes of his father, brother, and milk sister, Lerche. Despite not fully understanding why it was wrong, he had vowed never to defy death again. That promise is shattered when a shell hits their base, and the real Lerche is mortally wounded after saving Vika’s life by pushing him out of harm’s way. Lerche’s final moments are emotionally charged. Despite her immense pain, she smiles and expresses love for her homeland and for Vika, asking him to protect the country after she's gone. She was more than a servant—she was Vika’s childhood companion and the one constant in his life. Her death reawakens his old temptation to defy death, and he begs her to stay with him. She agrees, unknowingly allowing herself to be turned into a Sirin—a reanimated, mechanized soldier. In the present day, Vika wakes in a dark, confined base near the frontlines of a siege.


It’s been three days since the battle began, and exhaustion hangs heavy over the soldiers. Lerche, now a Sirin with no memory of her past, remains by his side. Vika uses their neural link to check on her unit’s status and hears the toll the ongoing siege is taking on everyone—especially Shin (Reaper), who can hear the voices of the dead even in his sleep. Vika and Lerche discuss Shin’s deteriorating mental state and the need to limit the Sirins' presence around him. Vika reflects on how Lerche, now a Sirin, doesn’t remember her past life—or at least pretends not to. There’s ambiguity around whether her emotions and words are echoes of who she was or programmed responses. Despite this, she still calls him "My lonely Prince Charming," evoking a ghost of her old self. Meanwhile, Lerche approaches Shin with concern, but the conversation turns confrontational. She mocks his reason for fighting—to avoid being pathetic—and reveals a deep-seated bitterness. As one of the dead, Lerche envies the living, lamenting that she can no longer seek happiness or love. Her speech is filled with rage and sorrow toward the living who take their second chances for granted. As the siege reaches a breaking point, Vika orders a full-scale offensive. The Sirins, particularly the Alkonost units, begin a suicidal charge. In a horrific and awe-inspiring act, they throw themselves into a trench, using their bodies to build a bridge so the human Juggernauts can climb the fortress wall. They do so joyfully, laughing as they die, proud to serve their purpose. The humans, especially the Eighty-Six, are horrified by the grotesque sacrifice. The Juggernauts, including Shin, reluctantly follow, walking over the crushed bodies of the Sirins. The moment is symbolic—survival in war often means stepping over the dead. Shin is deeply shaken, especially when he crushes a still-moving Sirin underfoot. He reflects bitterly that he has always walked on a path paved by corpses, and this moment is a literal manifestation of that truth.

The Phönix, a fearsome Legion unit, reappears on the battlefield with new enhancements, including fluid-like metallic wings and a restructured armor that eliminates its prior weaknesses. Its speed and agility surpass anything the defenders have seen, rivaling even the most advanced Legion units. The battlefield becomes a chaotic clash as Lena and her team analyze its changes and realize that Shin’s earlier report on its vulnerabilities has become outdated. Nevertheless, the defenders rally, initiating a coordinated attack that lures the Phönix using Shin as bait. Despite its incredible mobility, a combination of proximity-fused munitions, cluster bombs, and overwhelming firepower forces it to retreat and take damage, revealing that the team’s tactical adaptation is effective. Lena and Frederica reflect on the cold necessity of using Shin as bait, recognizing that Phönix's primary goal is his capture. By understanding its objectives and using wide-area suppression tactics, they exploit its obsession and overconfidence. The coordinated ambush demonstrates the strength of collective strategy over individual might, a cornerstone of the Eighty-Six’s combat philosophy. In the end, the Phönix is surrounded, and Lena acknowledges that while its speed is unmatched, it’s not invincible—just a problem of area control and timing.

The battle against the Phönix raged with overwhelming intensity, resembling a high-stakes hunt for a ferocious and cunning beast. The Juggernauts had meticulously laid traps all over the battlefield—from rooftops and spires to maze-like corridors—encircling the elusive Phönix from every angle. Despite their efforts, the Phönix, cloaked in optical camouflage and armed with liquid, adaptive armor, maneuvered with terrifying agility, evading ambushes and unleashing devastation wherever it went. Buckshot mines, missiles, and machine-gun fire filled the air as Lena coordinated squadrons in real-time, trying to contain the chaos while Shin, gifted with preternatural perception, directed pinpoint strikes. The Phönix adapted quickly, using its shapeshifting armor to both defend and attack—reforming into high-velocity fléchette cannons and slashing with chain blades that sliced through even the strongest defenses. As the encirclement began to crumble and the Juggernauts suffered losses, the Phönix punched through the weakened formation, bearing down on critical units. Cyclops fell despite a desperate counterattack, and the Phönix ultimately broke free of the trap, heading straight toward Shin’s unit, the Undertaker.

Lena watched in shock as the Phönix managed to break through the blockade, forcing the Undertaker to stay in battle even without ammo. The Phönix, faster and better armed for melee combat, clashed fiercely with Undertaker, damaging it severely. Shin, having switched from the disabled Undertaker to the Chaika mech, took advantage of the Phönix’s momentary vulnerability and launched a surprise attack from behind. Despite his close-range shot missing its full impact due to the Phönix’s incredible speed, the battle intensified. Meanwhile, Lerche, wounded but unyielding, leapt from the damaged Undertaker and engaged the Phönix in brutal hand-to-hand combat. Using a high-frequency blade, she managed to tear through the Phönix’s armor, inflicting critical damage even as she suffered severe injuries herself. As the Phönix prepared to retreat, weakened and weaponless, Shin locked onto the target with renewed determination after exchanging a fierce glance with Lerche, commanding a final shot to finish the fight. Shin hesitated for a moment, wondering if he would have held his fire if begged to stop, but his battle-trained instincts took over, and he fired. The armor-piercing round tore off the Phönix’s arm and ignited its core, but the machine’s swarm of silver butterfly-like modules escaped into the snowy sky. Observing from afar, Vika reflected on the Phönix’s strange nature—while powerful, it was inefficient compared to mass-produced Legion units, and its apparent self-preservation was an oddity for the Legion’s usual strategy of ruthless extermination. The escaping modules led to a surprising sight: a lone, aged white Ameise mech, unlike any other Legion unit, standing on the battlefield with a symbol of a goddess on its shoulder. This was the legendary Merciless Queen, a rare, almost mythical commander unit surrounded by loyal Dinosauria guards. As the Merciless Queen acknowledged the watchers with a voice both merciless and faintly sorrowful, Shin was flooded with memories of his lost family and past life—things he had suppressed to survive the cruelty of the world. Despite the queen’s fearsome presence and the dark weight of war, no one pursued it as it retreated with its protectors into the snowy darkness. The silent departure of this enigmatic figure left the observers unsettled, signaling a deeper mystery behind the Legion’s creation of such a unique and seemingly immortal weapon.
