Chapter Summaries

Miyuki Shiba told Yunyi she feared Tatsuya Shiba would be drawn into the Parasite crisis, but volunteered to help alongside Fumiya while keeping her brother out of it. After Kei Isori and Kanon Chiyoda were attacked, Yunyi discovered a Parasite inside the unconscious Kanon and called Miyuki to use Mental Interference Magic.

• Miyuki Shiba asked Yunyi to keep Tatsuya Shiba out of the operation, then offered to help him with Fumiya and Yuuka Tsukuba.
• Yunyi and Mayumi Saegusa spent the day searching for intelligence, but found nothing useful.
• Mayumi Saegusa received word from Katsuto Jumonji that Kei Isori and Kanon Chiyoda had been attacked, leaving one seriously injured and the other unconscious.
• Katsuto Jumonji told Yunyi that Kanon had lost nearly half her blood and that her symptoms matched those of Parasite victims.
• Yunyi examined Kanon Chiyoda in intensive care and detected nonhuman fluctuations in her body, identifying a likely Parasite infestation.
• Yunyi called Mayumi Saegusa and Miyuki Shiba, then asked Miyuki to hypnotize the Parasite with Mental Interference Magic.

Yunyi and Miyuki Shiba drove a Parasite out of Kanon Chiyoda and Yunyi banished it to Imaginary Number Space. After learning that American forces had departed Gibraltar and Lina had gone off with STARS personnel, Yunyi suspected Gu Jie was engineering a conflict and set out to find Lina.

• Miyuki Shiba used Mental Interference Magic while Yunyi shared his observations, causing the Parasite to flee Kanon Chiyoda; Yunyi blocked it from reaching Mayumi Saegusa and Miyuki Shiba, then banished it to Imaginary Number Space.
• Tatsuya Shiba examined Kanon Chiyoda and reported that her weakened condition came mainly from blood loss, while Yunyi expected her to survive without the Parasite.
• Suzune Ichihara told Yunyi that Lina had hurried away after receiving a phone call, prompting him to suspect that STARS personnel were in danger and that Gu Jie was trying to provoke a conflict between Japan and America.
• Yunyi ordered intelligence personnel to investigate American STARS and Gibraltar Military Base, then learned that troops had left Gibraltar aboard warships ten days earlier.
• Yunyi put on his black cloak and told Mayumi Saegusa he was going to find Lina.

Mayumi Saegusa’s sisters stayed with her after Yunyi left to search for Lina and the “Parasites.” Yunyi found a group heading toward a remote park, where Lina was fighting the Parasites and struggling to protect Claire and Rachel.

• Kasumi Saegusa and Izumi Saegusa joined Mayumi Saegusa to keep her company while Yunyi was away.
• Yunyi used Domain Expansion to detect three figures with unstable psion fluctuations moving through Tokyo’s alleys.
• Yunyi saw the three figures join two others and head toward a remote park, then hurried there to investigate.
• After two STARS members were parasitized and the Parasites learned their unit’s movements, the military ordered Lina to hunt them down and execute the infected members.
• Lina told Claire to retreat with the injured Rachel as more Parasites overwhelmed her, then cast a spell to bind them.

Yunyi arrived at the park and used his magic to restrain the Parasites and protect Lina and the STARS members. The Parasites fused and attacked with energy blasts, leaving Claire and Rachel's fate unclear as Yunyi prepared to strike back.

• Yunyi bound the Parasites with a magic circle and forced the STARS members to bend under his gravity magic until Lina told him they were her teammates.
• The Parasites freed themselves from their hosts, fused, and attacked Yunyi, but he stopped the Psions throughout his domain.
• More than a dozen Parasites abandoned their hosts and fused into one powerful being that fired energy blasts at Yunyi and the STARS members.
• Yunyi shielded Lina and the others, but the blasts engulfed the area where Claire and Rachel stood, and Lina began to fall.
• Yunyi raised his palm toward the attacking Parasites and cursed them.

Yunyi drove off the Parasites and took Lina away after she blamed him for failing to save the STARS members. He then gathered Yuuka Tsukuba and Miyuki Shiba to help him track and capture the Parasites that night.

• Yunyi used Gravity Core and a hypnotic spell to disrupt the Parasites, which fled before he could capture them.
• Lina questioned Yunyi, and he slapped her to bring her to her senses before taking her away from the park with Ben’s permission.
• Yunyi brought Lina home, asked Mayumi Saegusa to look after her, and warned the household that Tokyo might be dangerous.
• Yunyi called Miyuki Shiba and Yuuka Tsukuba to recruit them for his plan to capture the Parasites.
• Yunyi used spatial magic to pick up Yuuka and Miyuki, then began briefing them on the night’s events.

Yunyi took Miyuki Shiba and Yuuka Tsukuba to the Parasites’ base on Tokyo’s outskirts, where all thirty-one Parasites had gathered. He sealed off the area’s Psion flow, and the Parasites charged at them as the hunt began.

• Yunyi told Miyuki Shiba and Yuuka Tsukuba that mental magic could eliminate the Parasites and urged them to act before Miyuki’s brother noticed she was gone.
• Yunyi flew Miyuki and Yuuka to the outskirts of Tokyo, where they prepared to attack the Parasites with mental magic.
• Yunyi cast Domain Expansion, Fool’s World, to seal off the Psion flow in the area.
• The Parasites sensed the Domain Magic, burst out of their warehouse, and charged toward Yunyi, Miyuki, and Yuuka.
• The Parasites’ base held all thirty-one who had come to Japan, including companions they had awakened after fleeing the park.

Yunyi and the two women fought the Parasites attacking them outside the warehouse. He left Miyuki and Fumiya to suppress the main Parasite while he charged at the possessed people to drive the Parasites out of their bodies.

• Yunyi sensed the Parasites and used magic to make the bullets fired at him, Miyuki, and Yuuka disappear.
• Yunyi lit up the darkness and struck the exposed hosts with Electric Light, but the main Parasite shielded them from the attack.
• Yunyi used Light Phosphorus to pierce the Parasite’s barrier and weaken its main body.
• Yunyi ordered Miyuki and Fumiya to attack the Parasite with Direct Pain while he dealt with the possessed people.
• Yunyi charged at the possessed people, intending to force the Parasites out and preserve their bodies for Lina’s sake.

Yunyi drove the remaining Parasites out of their STARS hosts and reunited them with the one he had banished, but the thirty-one merged Parasites resisted Miyuki Shiba and Yuuka Tsukuba’s magic. With Cocytus unavailable because of the seal on her brother’s abilities, Yunyi prepared to kill the Parasites as they attacked.

• Yunyi used his sword and protective magic to defeat the possessed STARS members, forcing their Parasites to flee their hosts.
• Yunyi released the Parasite he had banished to Imaginary Number Space, allowing all thirty-one Parasites in Japan to merge.
• The merged Parasites resisted Miyuki Shiba and Yuuka Tsukuba’s Mental Interference Magic and attacked them with a blast of energy, which Yunyi’s defensive magic blocked.
• Miyuki Shiba told Yunyi she could not use Cocytus without undoing the seal on her brother’s abilities, and Yunyi prepared a killing move against the Parasites.

Gu Jie sent Zhou Gongjin’s subordinates to capture the Saegusa Family’s daughters while Yunyi was away, despite Zhou Gongjin’s doubts. As the attack began, a Psion vortex and a beam of light struck the raiders outside Yunyi’s home.

• Gu Jie decided to exploit Yunyi’s absence and ordered an attack on the Saegusa Family’s daughters.
• Zhou Gongjin’s subordinates, including five Executors and several magicians, approached Yunyi’s mansion.
• The magicians hid in the darkness as the Executors prepared to break into the mansion.
• When the mansion’s second-floor lights went out, the Executors charged, and a vortex of Psions sent icicles raining down on them.
• A beam of white light shot from a second-floor window, pierced an Executor, and scorched the ground.

Mayumi Saegusa and Lina prepared to defend the mansion after detecting an armed group outside. When the attackers moved in, Mayumi used her Engraving Type to cast a powerful spell almost instantly, surprising Lina and herself.

• Mayumi Saegusa asked Lina how she had been injured, and Lina said Yunyi-kun had slapped her because their positions were opposed.
• Lina said she had to wait for orders from her superiors, while Mayumi Saegusa worried about Yunyi-kun hunting the Parasites.
• Lina detected sixteen people outside the mansion, including five modified humans, and Mayumi brought Kasumi Saegusa and Izumi Saegusa to the guest room.
• Mayumi proposed using the darkness to lure the attackers into moving, and she and Lina prepared to strike when Kasumi turned off the lights.
• Mayumi's Engraving Type spell pierced an executor who climbed over the wall, astonishing Lina with its speed and power.

Yunyi protected Miyuki Shiba and Yuuka Tsukuba from corpses detonated by a Necromancy Technique, while the Parasites fled into his barrier and found a possible way out. At home, Mayumi Saegusa and Lina dealt with the attackers as Yunyi’s guards intercepted the retreating magicians.

• Lina helped Mayumi Saegusa defeat the Executors outside the house, and Mayumi detected the remaining magicians trying to retreat.
• Two masked guards wearing robes like Yunyi’s appeared in the magicians’ path and blocked their escape.
• Yunyi noticed something strange about two corpses and pulled Miyuki Shiba and Yuuka Tsukuba behind him before the corpses exploded.
• Yunyi identified the explosions as a Necromancy Technique and saw that the Parasites had fled the blast.
• The Parasites attacked Yunyi’s barrier but failed to break through, then spotted a ray of hope.

Tatsuya Shiba rushed toward the formation to find Miyuki, while Yunyi feared he would be caught by the Parasites. Yunyi unleashed Spatial Collapse to destroy the Parasites before Tatsuya could reach them.

• Tatsuya woke from Miyuki's Mental Interference Magic and sensed her location through their contract.
• Tatsuya sped toward the warehouse, unaware that Yunyi, Miyuki, and Yuuka were approaching the formation.
• Miyuki recognized Tatsuya, and Yunyi realized Tatsuya might charge into the Parasites.
• Yunyi gathered Psions and cast Spatial Collapse at the Parasites on the formation's edge.
• The magic shattered space and created a confined pseudo-black hole around the Parasites.

Yunyi destroyed the Parasite with an artificial black hole, then fled with Yuuka Tsukuba before Tatsuya Shiba could confront him. Back at his courtyard, he found signs of an attack and questioned his guard.

• The artificial black hole tore the Parasite apart, and Yunyi escaped with Yuuka Tsukuba through the Gate of Transfer.
• Tatsuya Shiba confronted Miyuki Shiba about going out late, and she weakly agreed to explain herself.
• Yunyi asked Yuuka Tsukuba to keep his magic secret, then left her bedroom through the Gate of Transfer.
• Yuuka Tsukuba realized Yunyi had not exchanged contact information with her and wondered if his offer to treat her was just a brush-off.
• Yunyi returned to his courtyard, noticed dark marks on the ground, and asked his guard whether someone had attacked the place.

After Zhou Gongjin escaped from the safe house, Yunyi ordered his people to withdraw and returned home, where he learned Kasumi and Izumi were sulking because Lina was staying the night. He explained the remaining Parasite threat to Mayumi Saegusa and Lina, then messaged Miyuki Shiba about the night’s events.

• Yunyi learned that Executors from Blanche had attacked his home and that Zhou Gongjin had escaped capture.
• Yunyi ordered the guards to withdraw from the safe house because Zhou Gongjin might retaliate.
• Kasumi and Izumi went upstairs sulking, and Lina said they were probably upset that she was staying the night.
• Yunyi told Mayumi Saegusa that Gu Jie had directed the Parasites to Japan and warned that others might remain in America or be summoned again.
• Yunyi asked Lina to have her deputy investigate Americans he had encountered, then sent her the location.
• Yunyi messaged Miyuki Shiba and told Mayumi Saegusa that Miyuki and the Tsukuba Family's eldest daughter had accompanied him while he hunted Parasites.

Yunyi learned that Kasumi and Izumi Saegusa opposed Lina living with them because they feared she would take him away, and he explained that he had no plans to leave or become a naturalized citizen. Lina remained in Japan after her failed Parasite-hunting mission, and she and Yunyi resumed bickering before Mayumi called everyone to breakfast.

• Yunyi questioned Kasumi and Izumi Saegusa about why they had skipped dinner and learned they disliked Lina moving into the house.
• Izumi Saegusa and Kasumi Saegusa admitted they feared Lina would take Yunyi away, and Yunyi clarified that they were only friends and he would not become a citizen of another country.
• Lina overheard Yunyi calling her silly and explained that she was still at First High School because her mission failed, STARS suffered heavy losses, and the military had issued no new orders.
• Yunyi advised Lina to leave the military before it used her up, and Lina angrily argued back.
• Mayumi Saegusa announced that breakfast was ready and called Kasumi and Izumi to help her.

After last night’s events, Yunyi reassured Tatsuya Shiba that he would protect Miyuki Shiba, though he acknowledged that their countries might one day make them enemies. The group arrived at First High School, where Yunyi and Miyuki sensed that something was wrong in class 1-A.

• Yunyi told Lina to stop sulking, and she joined the others for breakfast before leaving to meet Ben.
• Yunyi and Mayumi Saegusa met Tatsuya Shiba and Miyuki Shiba at the automated car station, and Yunyi walked off with Tatsuya to speak privately.
• Tatsuya asked Yunyi not to take Miyuki out alone again, and Yunyi promised to keep her safe while warning that they might one day meet as enemies.
• Miyuki told Mayumi what had happened the previous night, and Mayumi advised her to tell Tatsuya if something similar happened again.
• Yunyi and Miyuki entered class 1-A and noticed that the atmosphere seemed unusual.

After learning that Shun Morisaki had died, Yunyi received intelligence that Japan’s military might be preparing a move against his side. He questioned Tatsuya about whether he would deploy with the 101, then told Lina he would fight if Japan’s military attacked.

• Shizuku Kitayama told Yunyi and Miyuki Shiba that Shun Morisaki had died while on leave from school.
• Yunyi received a grave message, visited his former classmates in Class E, and took Tatsuya to the Public Morals Committee office.
• Yunyi showed Tatsuya intelligence from Liu Yunde about a possible Japanese military operation and asked what he would do if the 101 deployed.
• Tatsuya said he did not know whether he would deploy, and Yunyi warned that he would not hold back if they came into conflict.
• Lina told Yunyi that Colonel Virginia had reported Japan’s military might be targeting his side, and Yunyi said he would fight if necessary.

Yunyi wondered why the Japanese military was preparing for a conflict, unaware that it intended to use war to forcibly recruit him. Maya Yotsuba decided to arrange a meeting with Yunyi, while First High School’s Thesis Competition team struggled to find a replacement for an injured member.

• Yunyi considered the Japanese military’s sudden preparations and failed to realize that it planned to conscript him by force.
• Koichi Saegusa, Shingon Kudou, Retsu Kudou, and Katsuto Jumonji investigated the military’s mobilization, while Maya Yotsuba suspected it wanted to recruit someone.
• Maya Yotsuba decided to meet Yunyi despite Hayama’s objection and asked him to make the arrangements.
• Mayumi Saegusa and the others struggled to find a replacement for Kei Isori on First High School’s Thesis Competition team.
• Yunyi entered the Student Council office and learned that they were worried about replacing Kei Isori.

Suzune Ichihara proposed that Liu Yunyi join the Thesis Competition team, but he declined because he had not researched its topic, a Gravity Control Magic Sequence Thermonuclear Reactor. Mayumi Saegusa and Yunyi left the Student Council room, while Suzune and Miyuki went to meet their companions.

• Yunyi asked why Suzune Ichihara seemed unconcerned about finding a competitor, and Suzune said she had someone in mind.
• Suzune named Yunyi, explaining that his unconventional ideas, including his Closed-Loop Theory, could help the team despite his poor theory grades.
• Yunyi refused to take part, saying his Gravity Interference Magic research did not apply to the reactor-related topic and he had not studied it.
• Yunyi told Suzune that Lina was waiting in the Public Morals Committee office and that Miyuki could go to Tatsuya.
• Yunyi left with Mayumi, who asked whether he truly could not help Suzune; he confirmed that he could not and comforted her.

Yunyi and Mayumi Saegusa shared a comfortable evening at home while Mayumi sorted intelligence and Yunyi explored his Domain Magic. Meanwhile, Gu Jie left Gibraltar Military Base and planned a trip to Japan to observe Yunyi and possibly attack him from the shadows.

• Kasumi Saegusa and Izumi Saegusa happily welcomed Yunyi and Mayumi Saegusa home, then relaxed while the two prepared dinner.
• Mayumi Saegusa reviewed and categorized intelligence as Yunyi explored his magical domain, still searching for a third stage of Domain Magic.
