Chapter 22–23 Summary: “Stinging Pain” / “Pursuit and Escape”

Key Plot Points and Events

• Anilas believes Efnir, empowered by her Apostle Form and surrounded by both Corruption Energy and Order Force, is strong enough to defeat the Angels.
• However, Efnir hesitates because the Angels are actually her former seniors, Qinglan and Flying Swallow. Both disappeared after the recent disasters and have since become Angels.
• Efnir struggles with whether she can kill them, remembering the earlier trauma of having to raise her gun against a senior who had become a Dreg.
• Flying Swallow, now the Crimson Angel, attacks first with a crimson beam. Efnir blocks it with white radiance, overwhelms Flying Swallow, and repeatedly suppresses both Angels.
• Despite sustaining severe wounds, Qinglan and Flying Swallow continue fighting like emotionless puppets, unaffected by pain or physical damage.
• Explosions in the distance signal that military forces are attacking. The Angels suddenly stop fighting and retreat, prompting Efnir to pursue them rather than let them escape.
• During the pursuit, Efnir and Anilas discover that the Angels are not alone. Apostles concealed within the fog ambush Efnir.
• Efnir identifies and defeats one female Apostle, knocking her to the ground and nearly killing her. She orders the girl to surrender but ultimately chooses not to strike the killing blow.
• When Efnir attempts to remove the girl’s Battle Armament, a mysterious violet flash causes intense pain in Efnir’s fingers, arm, brain, and right eye. The girl’s armament then disengages on its own.
• Efnir successfully removes the girl’s silver ring, recognizing it as an Apostle Beacon or Sacred Relic, though it seems subtly different from her own.
• As the chapter ends, Anilas runs to check on Efnir while remaining wary of further enemies hidden in the fog.

Character Developments

• Efnir: Reveals deep emotional conflict and unresolved guilt over fighting former comrades who have become monsters. Although she is capable of killing both Angels, she repeatedly restrains herself and chooses capture or suppression instead. Her mercy toward the defeated Apostle reinforces that she still values lives, even enemy ones. The strange violet pain introduces a possible weakness or new mystery connected to Apostle Beacons.
• Anilas: Acts as Efnir’s observer, supporter, and warning voice. She understands Efnir’s overwhelming power but worries that emotional hesitation may endanger her. She also responds quickly during the ambush and remains vigilant after the battle.
• Qinglan and Flying Swallow: Their transformation into Angels is emphasized through their inhuman, puppet-like movements and inability to feel pain. Their former identities remain important to Efnir, making them more than ordinary enemies.
• The unnamed female Apostle: Though initially presented as an enemy determined to attack Efnir, her fear and hatred suggest personal motives or a traumatic history. Her survival and unusual armament disengagement leave her role unresolved.

Significant Themes

• Humanity versus monstrosity: Qinglan and Flying Swallow retain familiar bodies but behave as emotionless, unnatural entities, forcing Efnir to question whether they can still be saved.
• The burden of choice: Efnir faces the recurring dilemma of whether to kill transformed comrades or search for another solution.
• Mercy and restraint: Efnir repeatedly refuses to deliver fatal blows, even when doing so would be easier or safer.
• Trauma and repetition: The present conflict mirrors Efnir’s earlier experience of confronting a senior who became a Dreg, suggesting that old wounds continue to shape her decisions.
• Hidden conspiracies and uncertainty: The Angels’ sudden retreat, the concealed Apostles, and the strange Apostle Beacon reaction imply that a larger operation or force is controlling events.
• Power and corruption: Apostle Power depends on the balance of Corruption Energy and Order Force, while the white fog and fallen Erosion Entities create the conditions that allow such power to flourish.

• Anilas admits that she has not told Maki about Efnir possessing an Apostle Beacon. Efnir is unconcerned, believing Maki may already suspect the truth.
• A nurse brings Efnir to a dying soldier undergoing Mutation. His body is being overtaken by Corruption Energy, and he will soon become a Dreg.
• Because no commanding officer is present, the nurse begs Efnir to execute the soldier before he loses himself and harms others. The soldier, who is the nurse’s lover, accepts that he cannot survive and asks Efnir to kill him.
• Efnir takes his bloodied hand and attempts to use her power, but the chapter ends with that power proving ineffective.

Character Developments

• Efnir, the nurse, and the soldier: The nurse pleads for Efnir’s assistance, and the soldier directly asks Efnir to execute him. Efnir responds with quiet empathy, but her inability to use her power leaves the situation unresolved and emotionally devastating.

Concise Chapter Summary

Key Plot Points and Events

• Efnir’s attempt to save a mutated soldier fails because her Apostle Form cannot respond to pure Corruption Energy. As the soldier’s Mutation worsens, he says a final goodbye to his lover, nurse Kururina.
• Efnir orders Anilas to escort Kururina away, then anesthetizes and kills the dying soldier with a gunshot, sparing him further suffering.
• Kururina refuses rest and immediately returns to the medical unit, insisting that she will not abandon her lover. Efnir reflects on how grief can drive survivors into relentless work and vengeance.
• Efnir struggles with the meaninglessness of the battle, the deaths caused by human conflict, and the lasting psychological wounds inflicted by the Erosion Entities and the “Dregs.”

Chapter Summary: About Becoming a Magical Girl

Key Plot Points and Events

• The chapter explains the continuing danger of Dregs, corpses or transformed humans that can remain motionless for days before attacking living beings. Some become especially powerful “Variants” after Dregsification, including former low-aptitude Eligibles or even fallen Agents.
• The unit’s Shielding Device is nearly out of energy, forcing Commander Kusei Maki and her surviving forces to retreat toward the Maesakagawa Garrison District and reactivate its Boundary Stele System.
• Jasmine is badly injured and requires urgent surgery, but the operation cannot wait. Maki orders her brought to the command room while the rest of the unit prepares to move.
• Maki divides the remaining forces into two teams:
  • Team A will use Lure Shells to draw Erosion Entities away from the Garrison District.
  • Team B will place detonators and use drones and explosives to slow the enemies’ advance.
  • The Agent Squad will clear the district of remaining Erosion Entities.
  • The engineering team must restart the Boundary Stele as quickly as possible.
• The assault begins with artillery destroying the Garrison District’s outer defenses. Armored vehicles and the train rush through the ruined streets while Lure Shells lure enemies away.
• The unit encounters large numbers of Dregs emerging from an overturned bus. Soldiers struggle to destroy them because ordinary gunfire often only dismembers them; precise shots to the head, neck, or spine are required.
• Agents intervene when the soldiers are overwhelmed, protecting the convoy and eliminating especially dangerous Dregs. Anilas leads the Agent Squad into the fighting.
• After more than fifteen minutes of intense combat, the unit reaches sight of the enormous Boundary Stele, giving the soldiers hope that the operation may succeed.
• The chapter ends by shifting to a deep underground location, where gunfire and explosions continue as an armored vehicle breaks through a wall, suggesting another battle or a parallel operation is underway.

• Yukina confronts the reality of war firsthand. The devastation, corpses, and violence deeply unsettle her, revealing her inexperience despite her mental preparation.
• Efnir acts as Yukina’s emotional support, urging her to focus and holding her hand to steady her during the advance.
• The soldiers show courage and cooperation under extreme pressure, while the Agents function as an elite reserve capable of handling threats ordinary troops cannot.

Significant Themes

• The irony of “specialness”: People with too little aptitude to become recognized Eligibles or Agents may gain dangerous abilities only after becoming Dregs. The system’s definition of who is “special” is exposed as arbitrary and tragic.
• The dehumanizing effects of war and catastrophe: Dregs retain traces of their former identities, such as their clothing, but have become violent, nearly unrecognizable creatures.
• Survival through strategy rather than strength: The forces cannot defeat every enemy directly, so they rely on diversion, explosives, maneuvering, and time management.
• The cost of protection: Agents are preserved for decisive battles, while ordinary soldiers bear much of the immediate danger. The chapter emphasizes the fragile structure of the unit’s defenses.
• Loss of innocence: Yukina’s reaction reflects her transition from an inexperienced young person into someone forced to witness and participate in mass violence.
• Hope amid destruction: The Boundary Stele represents safety and isolation from the surrounding horrors, and its appearance briefly lifts the soldiers’ morale.

Character Interactions

• Maki gives Anilas operational orders and discusses Jasmine’s worsening condition, balancing concern for casualties with the urgency of the mission.
• Efnir comforts Yukina and explains why the Apostles likely chose the Garrison District, helping Yukina understand the tactical situation.
• Yukina and Efnir support each other physically and emotionally as the convoy advances.
• Soldiers and Agents cooperate closely: ordinary troops engage the massed Dregs, while Agents eliminate threats too powerful or difficult for them to handle.

Chapter Summary: “About Becoming a Magical Girl”

Key Plot Points and Events

• Efnir, Yukina, and their forces arrive at the ruined Boundary Stele Administration hall. The area is deserted, littered with corpses, wreckage, burned vegetation, and spent weapons, showing that the defenders were overwhelmed after the Garrison District’s agent died.
• Kusei Maki divides the operation into two teams:

• Efnir reaches the lower floors first, breaking through barricades, killing Dregs, and destroying a warped security door. Her attack awakens many more monsters throughout the underground complex.
• Using Lure Devices to divert some of the Dregs, Efnir provides an opening for Kusei Maki and the assault squad to advance. They establish positions and unleash suppressive fire.
• Kite seals off another passage with debris while the remaining soldiers defend the team from behind. A large-scale battle begins as Dregs pour through the corridors from every direction.
• Despite heavy gunfire, the Dregs continue attacking even after suffering massive injuries, turning the fight into a desperate struggle to hold the underground passages.

Character Developments

• Efnir remains calm and decisive despite the horrific surroundings. She takes responsibility for the most dangerous task—jumping into the elevator shaft alone—and demonstrates her exceptional combat abilities by destroying multiple Dregs and clearing the route.
• Yukina is visibly shaken by the corpses, blood, and stench, but refuses to withdraw. Efnir supports her by lending her protective equipment and encouraging her to use Order Force to steady herself. Yukina ultimately follows Efnir into the shaft, showing courage despite her fear.
• Kusei Maki acts as a capable commander, quickly organizing the teams, adapting to the collapsed stairways, and leading the assault personally. Her trust in Efnir allows the operation to proceed efficiently.
• Kite takes on a defensive leadership role, guiding the remaining soldiers and sealing the rear passage to prevent the group from being surrounded.
• The soldiers and engineers work cooperatively under extreme pressure, with the engineers contributing to the defense rather than remaining passive.

Significant Themes

• The aftermath of defeat: The ruined Administration hall and piles of corpses reflect the devastating consequences of losing a single key defender and the inability of ordinary forces to stop the Erosion Entities.
• Duty and sacrifice: The mission requires the characters to enter a dead, contaminated battlefield and risk their lives to restore the Boundary Stele, emphasizing collective responsibility over personal safety.
• Courage under fear: Yukina’s anxiety contrasts with her determination to continue fighting, suggesting that bravery means acting despite terror rather than being fearless.
• Human technology versus monstrous persistence: Guns, barricades, and tactical equipment help the soldiers hold their ground, but the Dregs’ resilience reveals how fragile human defenses are.
• Cooperation and trust: The assault succeeds through coordinated roles—Efnir’s vanguard attack, Maki’s command, Kite’s rear defense, and the engineers’ technical work.

Character Interactions

• Efnir notices Yukina’s distress and quietly helps her without belittling her fear. Yukina insists she can still fight, reinforcing her determination to prove herself.
• Efnir reassures Yukina before descending into the shaft, and Yukina follows her after a moment of hesitation.
• Kusei Maki relies on Efnir’s judgment when the stairwell cannot be opened, granting her permission to take the dangerous route.
• Maki and Efnir coordinate the advance: Efnir draws away and attacks the Dregs, while Maki’s squad uses the opportunity to move in and provide suppressive fire.

Chapter 170 Summary

Plot and Major Events

• The assault team continues fighting through the underground facility toward the central control room. Because explosives and heavy weapons could trigger collapses, secondary explosions, or damage sensitive equipment, they are limited to firearms and magical abilities.
• The stairwell is overwhelmed by a massive swarm of Dregs emerging from the damaged passage between floors B7 and B8. Ordinary gunfire is insufficient to stop them.
• Yukina uses “Fifina” to unleash a powerful blue arrow and hurricane-like blast, annihilating much of the swarm. The surviving Dregs are finished off by the soldiers.
• The soldiers nearly exhaust their ammunition, but the route to the control room is cleared. Kusei Maki orders everyone to keep moving rather than pause.
• At the central control room, Efnir enters first and is attacked by a hidden Mutated Entity. She instantly kills it by piercing its head with her spear.
• The engineering team begins restoring the Boundary Stele System and reconnecting temporary power. Meanwhile, soldiers sweep the entire floor for remaining Dregs and secure the area.
• Kusei Maki tells Efnir to rest instead of joining the sweep, preserving her strength for the more dangerous confrontation with the Erosion Entities.
• During the break, Efnir offers Yukina a chocolate energy bar. Yukina refuses because the blood, corpses, and smell make her nauseated. Once ventilation is restored, she removes her gas mask briefly, but soon puts it back on.
• The chapter ends with Yukina moving closer to Efnir and leaning against her, calling her “Naoko,” suggesting an intimate or emotionally significant exchange is about to follow.

Character Development

• Kusei Maki demonstrates careful tactical judgment and leadership. She balances the need to advance quickly with concerns about ammunition, structural damage, and preserving Efnir for the upcoming battle.
• Yukina proves how devastating and useful her abilities are against tightly packed enemies. Her continuous, high-powered arrows make her especially effective in confined spaces. However, she remains physically and psychologically affected by the horrific environment, reminding her that she is still adapting as a new Agent.
• Efnir continues to display overwhelming combat ability, killing the Mutated Entity effortlessly. Her ability to eat and function normally amid the grotesque surroundings emphasizes her superior Agent conditioning. At the same time, her thoughts reveal anxiety about facing Apostles, which she considers more frightening than ordinary Erosion Entities.
• Kite recognizes Yukina’s effectiveness and briefly feels disappointed that she was not needed during the stairwell assault. This reflects both her readiness to protect the group and her awareness of Yukina’s growing strength.
• The soldiers are shown as disciplined but strained. They expend much of their ammunition, endure extreme environmental conditions, and methodically finish off even badly wounded Dregs.

Themes

• Adaptation and the limits of humanity: Yukina’s nausea and reliance on her gas mask contrast with Efnir and Kite’s ability to ignore the toxic air and horrific conditions. Yukina is powerful, but she has not yet fully abandoned ordinary human responses.

• At Xijing City United Airport, Elincia is introduced to a masked operative called Shadow, who will be her partner. Shadow’s voice and silver ring strongly remind Elincia of Furan, causing her to suspect that Shadow may be connected to her.
• In a ruined apartment building near the Relay Station, an Apostle squad prepares to deploy. These girls possess insufficient compatibility to awaken true Beacons or Sacred Relics and instead use inferior artificial relics and an “Enhancement Agent” to temporarily increase their abilities.
• Fujisaki Ryoka, the squad’s captain, watches Efnir’s battle and recognizes that Efnir is weakening. She orders the squad to prepare for an attack.
• Ryoka argues with Hatsukawa Fuka, her childhood friend. Fuka questions whether they truly need to fight and suggests that their fate might be changed through negotiation rather than war. Ryoka rejects this idea, insisting that the oppression and deaths they suffered can only be answered through force.
• Ryoka injects herself with the Enhancement Agent, and the other girls follow. Fuka hesitates but ultimately injects herself as well. The drug strips away much of her sorrow and uncertainty, leaving behind anger and hatred, while dangerous crimson energy appears in her eyes.
• The chapter ends by explaining the nature of Corruption Energy: conventional physical attacks cannot effectively harm Erosion Entities because the entities can cause Corruption Energy to ignore bullets and explosions, while selectively allowing it to generate destructive physical effects when attacking.

Character Developments

• Efnir: Demonstrates immense strength and determination but is visibly approaching her physical and energetic limits. Her struggle emphasizes the burden of protecting an entire battlefield alone.
• Yukina: Perceives Efnir’s weakening condition and becomes increasingly aware of how precarious their defense is.
• Elincia: Remains outwardly composed but becomes suspicious of Shadow after recognizing the familiar silver ring and mannerisms associated with Furan.
• Fujisaki Ryoka: Is portrayed as a hardened, uncompromising leader. Her trauma has convinced her that sacrifice and violence are necessary for survival and change.
• Hatsukawa Fuka: Retains empathy and doubts the necessity of war, setting her apart from Ryoka and the rest of the squad. However, the Enhancement Agent suppresses her hesitation and transforms her emotions into hatred, suggesting a loss of identity and autonomy.
• The Apostle squad: Their status as expendable, low-compatibility fighters is emphasized. Despite their inferior powers, their numbers and coordinated tactics make them a serious threat.

Significant Themes

• The cost of power and protection: Efnir’s declining strength shows that even extraordinary power has limits, especially when one person is forced to protect many others.
• War versus reconciliation: Fuka’s desire for negotiation clashes with Ryoka’s belief that violence is the only path to justice, presenting two opposing responses to trauma and oppression.
• Dehumanization and expendability: The Apostle Organization treats its low-compatibility fighters as disposable weapons, exploiting their bodies with artificial relics and dangerous enhancement drugs.
• Loss of identity: The Enhancement Agent suppresses fear, grief, and compassion, replacing them with aggression. Fuka’s transformation illustrates how war can erase a person’s individuality.
• Quantity as power: Individually weak Apostles can become formidable through numbers, coordination, and technology.
• Hidden identities and suspicion: Shadow’s resemblance to Furan introduces uncertainty and suggests concealed connections among the characters.

Character Interactions

• Efnir and Yukina: Fight together while Yukina observes Efnir’s deteriorating condition and understands the strain of her protection.
• Elincia and Shadow: Meet as assigned partners. Their brief handshake becomes significant when Elincia notices Shadow’s familiar silver ring.
• Ryoka and Fuka: Clash over whether violence is necessary. Their shared childhood and past trauma make the disagreement especially painful, with Ryoka responding through anger and intimidation.
• Ryoka and the Apostle squad: Ryoka acts as their unquestioned leader, motivating them to inject themselves and attack while the enemy is weakened.
• Fuka and the Enhancement Agent: Fuka’s hesitation gives way to forced participation, and the drug fundamentally alters her emotional state as she follows Ryoka into battle.
