• Saori questions Karina about treatment for Corruption. Karina confirms that the Orderkeepers possess inhibitors or related technology and hands over a storage card containing information about them. She warns that the organization’s base changes location and requires an insider’s introduction to access.
• Saori then demands another Sacred Relic, claiming she wants to regain the Apostle’s power. Karina refuses, explaining that her squad has only two Sacred Relics.
• Pretending to agree to help Karina escape, Saori injects her with a tranquilizer. Karina loses consciousness after Saori smugly thanks her for the information.
• A report reveals that one target—Codename H—escaped the encirclement. The operation caused thirty-seven special-operations injuries, two deaths, and injuries to two Agents.

Hina explains that the storage card is partially encrypted and questions Karina about the person she contacted that night, implying that Saori has handed Karina over to the authorities or is cooperating with them.
• The chapter then shifts to the following day. Efnir has not yet been informed of the previous night’s classified events because she is still recovering from her injuries.

• Efnir: Acts as Yukina’s caretaker and instructor, balancing concern for Yukina’s injuries with the need to train her rigorously.

Themes

• Efnir reveals that humanity has only deciphered and activated less than thirty percent of the Beacon System. The currently usable functions include combat attire, the Stairway, and Order Weapons, while other potential abilities—such as defensive “shields”—remain inaccessible.

• Erii and the girl: Erii takes charge and tries to force the girl to evacuate, while the girl remains calm and insists that Erii leave her behind. Their relationship reverses when Erii is injured and the girl steps forward to protect or confront the approaching Entity.
• Erii and Naoto’s memory: Erii’s imagined comparison with Naoto functions as an internal interaction, motivating her to act according to the values she associates with him.

Chapter 138 Summary

Key Plot Points and Events

• After the battle with Codename H’s hooded girl, Efnir and Yukina receive medical treatment. Yukina is visibly distraught over Efnir’s injuries, while Efnir comforts her and gently wipes away her tears.
• Masaki Hina contacts Efnir with an important discovery made from analyzing battle recordings. Efnir and Yukina travel to Orderkeepers Central Command, where the other surviving participants in the operation have gathered.
• Hina reveals that the location mentioned by Codename H—Liujin City—is more than 200 kilometers from Xijing City and is classified as a Dead City, a settlement destroyed by an Erosion Disaster.
• Investigators discover that Liujin City’s final distress signal was sent on the same day as the Western Capital University disaster two years earlier. The city’s Boundary Stele System had apparently malfunctioned before the disaster, yet this crucial information was omitted from its aid request.
• The circumstances resemble the Apostle’s known tactics: sabotaging Boundary Steles, falsifying or suppressing signals, and delaying Human Federation rescue efforts until a city becomes impossible to save.
• Hina and Ayaka suspect that the Apostle may have been active as early as two years ago and may have caused Liujin City’s destruction. Codename H’s appearance at the university plaza may also have been connected to something hidden there, prompting a search of the area.
• The chapter ends with the group realizing that Xijing City could have suffered the same fate as Liujin City if the Apostle’s recent plan had succeeded.

Character Developments

• Efnir/Naoko: Despite her injuries, Efnir remains composed and focused on the investigation. She shows tenderness toward Yukina and begins connecting the Apostle’s current activities to older tragedies.

• The assembled magical girls: Their injuries and presence emphasize the cost of the battle and the seriousness of the ongoing conflict.

Significant Themes

• The Apostle’s long-term influence: The chapter suggests the Apostle may not be a recent organization but a hidden force operating for years.
• Institutional neglect and human disposability: Liujin City was abandoned because it was considered too remote and too difficult to save, illustrating how the Federation treats the destruction of entire cities as routine.
• The fragility of civilization: Cities are portrayed as isolated remnants of humanity, vulnerable to collapse when their defensive systems fail.
• Emotional bonds amid crisis: Efnir and Yukina’s interaction contrasts personal care and affection with the military-scale threat surrounding them.

Chapter 139 Summary

Key Plot Points and Events

• Efnir, Fushihara Ayaka, and Masaki Hina analyze the threat posed by the Apostle Organization after its attack on Xijing City.
• They conclude that the Apostles possess unknown Ruins Technology, which may allow them to transform Eligibles into powerful beings like Angel. Qinglan’s transformation is cited as proof that the Apostles are rapidly increasing their strength.
• Flying Swallow’s disappearance raises concern that she may also have been converted into an Angel.
• Evidence from Karina and an encrypted memory card suggests that Liujin City, now a Dead City, is connected to the Apostles. It may be their base, a trap, or a deliberate decoy.
• The group discovers that Liujin City had been completely stripped of supplies—including food—before official investigation teams arrived. This strongly suggests that someone had secretly occupied or searched the city.
• A previous investigation team stationed in Liujin City was almost entirely annihilated by an S-Rank Erosion Entity. Only two soldiers survived, and both later died under suspicious circumstances.
• Masaki Hina argues that the survivors may have been messengers or decoys, implying that the incident could have involved the Apostles rather than merely an Erosion Entity.
• The group decides that waiting for another Apostle attack is unacceptable. Masaki proposes an expedition to Liujin City to uncover why the Apostles targeted Xijing City and identify the source of their Ruins Technology.
• Shinomiyami Nami objects, warning that Xijing City may lack the strength to confront the Apostles directly and suggesting that the Human Federation should handle the investigation.

Character Developments

• Efnir is reaffirmed as Xijing City’s most dependable combatant. Her past victories against Special A-Rank disasters, a Quasi-S-Rank Erosion Entity, Angels, and Codename H have made her a symbol of hope.
• Masaki Hina reveals, indirectly, how deeply Efnir has influenced her. Efnir helped her recover her courage and ideals after she became disillusioned by political struggles and hardship.
• Masaki also demonstrates her growth as a commander: although she cares deeply about Efnir and the city’s survivors, she remains cautious and refuses to initiate a battle without preparation.
• Fushihara Ayaka contributes strategic analysis, recognizing that the Apostles’ hidden organization and unfamiliar technology may pose a threat far beyond the recent attack.
• Nami emerges as the voice of caution, emphasizing the danger of acting beyond the city’s capabilities.
• Ayse and Furan are particularly affected by the Apostles’ actions because Canary and Lily—their closest companions—were endangered or taken from them.

Significant Themes

• The danger of Ruins Technology: Ancient technology has the potential to surpass human control and create weapons or beings such as Angels.
• The burden of survival: Those who remain alive must continue fighting while carrying the will and memories of fallen, missing, or incapacitated comrades.
• Hope versus realism: Efnir represents courage and reassurance, while Nami’s objection highlights the need to recognize the limits of their strength.
• Hidden histories and deception: The strange events in Liujin City, the missing supplies, and the suspicious survivors suggest that the Apostles manipulate information and operate through disguises or smokescreens.
• Leadership and inspiration: Efnir’s strength is not merely physical; her determination inspires others, especially Masaki, to resist despair.

Character Interactions

• Efnir, Ayaka, and Masaki engage in a tense strategic discussion about the Apostles’ scale, resources, and possible headquarters.
• Masaki openly relies on Efnir’s experience with high-level threats, particularly S-Rank entities.
• Masaki’s private reflections reveal her admiration and emotional attachment to Efnir, while also acknowledging that Efnir’s heart belongs to Shiomi Yukina.
• The meeting’s atmosphere becomes heavier as the participants recall their dead, missing, and injured comrades.
• Nami’s interruption challenges Masaki’s proposed offensive and introduces a conflict between proactive investigation and cautious reliance on the Human Federation.

Chapter Summary

Key Plot Points and Events

• Xijing City’s remaining forces are insufficient to continue large-scale operations against the Apostle. Shinomiyami Nami raises this concern, while Efnir agrees that investigating the Apostle is essential but must be balanced against the city’s limited strength.
• Masaki Hina announces that reinforcements from the Human Federation will arrive that night. Their arrival will resolve the manpower shortage and eventually be publicly announced alongside a new command structure.
• Hina presents a three-stage operation to investigate fallen Liujin City:

Maesakagawa Recapture Operation

Forward Base Establishment Operation

Liujin City Investigation Operation

• Since Liujin City’s airport is destroyed and land travel would strain the massive Shielding Device, the team plans to travel by river. They will enter the main river through a tributary near Maesakagawa and proceed to Shimokitazawa, an abandoned water-control town near Liujin City.
• The team intends to reactivate Shimokitazawa’s Boundary Stele System and power grid, transforming it into a forward base for the investigation.
• The operational planning meeting lasts until nightfall. Hina and Bushiyuan must also welcome the Federation’s incoming reinforcements and prepare for their formal succession announcement.
• Hina privately asks Efnir and Yukina about whether Yukina has ever uploaded cover songs online. She then reveals a mysterious recording connected to Efnir’s past.
• During the disappearance of Codename H, Efnir’s terminal received strange glass-like static. When analyzed, the noise contained over 1,200 hidden recording fragments totaling more than 2,355 hours of data. The files span several years and appear to be combat recordings.
• Most frequently appearing among the fragments is one of Efnir’s songs—but the singer is not Efnir. The voice appears to belong to her younger sister, Shiomi Yukina.
• The recordings are marked with the codename “Ephnel,” even though Efnir was still an ordinary person under the name Yanase Naoto during the recordings’ timeframe. This suggests that another Agent once used the same codename.
• The chapter ends by explaining that Agent Beacons are rare, incomplete adaptations of Ruins technology. Normally, each city receives only one Beacon of a given codename, making the existence of another “Ephnel” highly mysterious.

Character Developments

• Masaki Hina demonstrates strong leadership and strategic responsibility. She balances the need to eliminate the Apostle with the practical limits of Xijing City’s forces and develops a workable plan using outside reinforcements and a river route.
• Shinomiyami Nami emerges as a cautious and realistic voice, concerned about exhausting the city’s remaining combat power. Her worries are validated, though the arrival of reinforcements reduces the immediate problem.
• Efnir reveals emotional uncertainty beneath her usual composure. The discovery that another Agent may have used her codename—and that the mysterious recordings are connected to her own song—forces her to question her identity and past.
• Yukina becomes directly implicated in the mystery. Her voice appears in the recordings despite the files predating Efnir’s transformation and her own supposed lack of uploaded songs. She is visibly shocked and uncertain.
• Fushihara Ayaka continues to act as a dependable officer, preparing to depart for the airfield and participate in the coming operation.
• Hina’s mention of possibly returning to Central Province shows that her role in Xijing City may be temporary, though she remains deeply invested in the city’s survival.

Significant Themes

• Duty versus limited resources: The characters must pursue the Apostle while acknowledging that heroism cannot erase practical military constraints.
• Rebuilding after catastrophe: The planned recovery of Maesakagawa, Shimokitazawa, and Liujin City represents an effort to reclaim abandoned infrastructure and restore strategic territory.
• Identity and duplicates: The appearance of another “Ephnel” challenges the assumption that codenames and Beacons correspond to unique individuals.
• Hidden data and suppressed history: The unexplained recordings suggest that crucial information may exist outside official archives, possibly connected to Ruins technology or anomalous events.
• The unreliability of time and memory: Recordings apparently created before Efnir became an Agent, yet carrying her codename and Yukina’s voice, imply that the past may have been altered, misidentified, or manipulated.
• Family and personal connection: The mystery becomes more intimate when Yukina’s voice links Efnir’s professional identity to her sister.

Character Interactions

• Nami voices her doubts about the city’s military capacity, and Efnir supports her concerns even while endorsing Hina’s investigation plan.
• Hina explains the reinforcement transfers to the group, establishing trust through transparency.
• Hina and Bushiyuan collaborate on the strategic plan, while the broader team participates in revising its details.
• Hina and Efnir discuss the future of Xijing City, with Efnir expressing hope that the city will survive after Hina returns to Central Province.
• Hina privately questions Efnir and Yukina, shifting the conversation from military planning to a deeply personal mystery.
• Efnir recognizes the song immediately as one of her own singles, while Yukina’s connection to the vocals leaves both sisters unsettled.
• The chapter closes with the sisters confronting the possibility that another Agent named Ephnel existed before Efnir, raising questions about their identities, the Beacon system, and the events surrounding Codename H’s disappearance.
