Chapter Summaries

Lin Xinyi struggled with whether to resist the organization, and Vermouth and Haibara Ai supported him despite the risks. He chose to maintain the status quo, but the next morning someone from Public Security knocked at his door.

• Lin Xinyi asked Vermouth and Haibara Ai about Pisco's supposed child and explained Pisco's dying message.
• Vermouth identified Pisco's child as Irish and offered to help Lin Xinyi use him to oppose the organization.
• Vermouth privately explained to Haibara Ai that their willingness to support Lin Xinyi would make him more cautious about risking their safety.
• After wrestling with his choice, Lin Xinyi decided to remain an undercover agent while avoiding the Japanese Public Security Bureau.
• The next morning, someone identifying themselves as Public Security knocked on Lin Xinyi's door.

Kazami Yuya and Furuya Rei visited Lin Xinyi to thank him and recruit him to investigate a suspicious killing. After Haibara Ai and Vermouth emerged from the bedroom, Lin Xinyi agreed to hear about the case but said he would help only this once.

• Kazami Yuya arrived with Furuya Rei, who probed Lin Xinyi's home and asked him to assist Public Security with a confidential investigation.
• Lin Xinyi refused, citing the danger he had faced the previous day, while the officers assured him the investigation would be safe and secret.
• Haibara Ai emerged from the bedroom, and Lin Xinyi explained that she had stayed over; Vermouth reinforced the cover story by acting affectionately toward her.
• Furuya Rei noticed signs that Lin Xinyi and Vermouth shared the home, then explained that a Hachibishi Company executive had been killed after Masuyama Kenzo's identity was exposed.
• Concerned that Public Security might scrutinize Haibara Ai, Lin Xinyi agreed to hear about the case but limited his offer to this one time.

Lin Xinyi examined the autopsy findings from Yamazaki Ken’s murder and concluded that the injuries were caused by ordinary household tools, making an organization connection unlikely. He identified the weapons but remained puzzled by how the killer had inflicted the wounds.

• Officer Kazami briefed Lin Xinyi on Yamazaki Ken’s death and explained that Public Security took the case because Yamazaki worked for Hachibishi Motors during an investigation involving Masuyama Kenzo.
• Lin Xinyi reviewed the autopsy report and identified two circular head wounds likely caused by a ball-peen or claw hammer.
• Lin Xinyi determined that the victim’s liver stab wound came from a single-edged blade about fifteen centimeters long, likely a long kitchen knife.
• Lin Xinyi concluded that the killer had used a household hammer and kitchen knife, making the case unlikely to involve the organization, though the wounds’ unusual pattern still troubled him.

Lin Xinyi explained why the murder was unlikely to be the work of the Criminal Organization, and Furuya asked him to help find the unprofessional killer. While Lin Xinyi reviewed the case files, Furuya questioned Haibara Ai’s unusual maturity, but she deflected suspicion by retrieving a toy and discussing Ultraman.

• Lin Xinyi argued that the killer’s use of two weapons and weak, restrained blows suggested the murder was not the work of a trained Criminal Organization assassin.
• Furuya explained that Public Security wanted to build a long-term collaboration with Lin Xinyi and asked him to help find the killer.
• Lin Xinyi agreed to review the files and inspect the crime scene, while Furuya approached Haibara Ai and asked why she was listening to a murder-case discussion.
• Haibara Ai claimed she was an adult and uninterested in cases, then retrieved an Ultraman figure from Lin Xinyi’s coffee-table drawer.
• Haibara Ai identified the figure as Ultraman Jack and explained how to distinguish it from the original Ultraman and Zoffy, easing Furuya’s suspicions.

Lin Xinyi reconstructed how the victim was attacked and left with Furuya Rei and Kazami to verify the crime scene. After they departed, Vermouth deduced that Furuya was disguised, and Lin independently suspected the same when he questioned him in the garage.

• Haibara Ai showed Furuya an Ultraman guidebook, and Lin Xinyi outlined how an acquaintance likely broke in to kill the victim for revenge.
• Lin explained that a hammer strike had missed the victim and damaged the sofa, then proposed that the victim fought back before the killer stabbed him in the kitchen.
• Lin left with Furuya and Kazami to inspect the crime scene, while Vermouth told Haibara that Furuya's face and voice were disguised.
• In the underground garage, Lin concluded from Furuya's age and his memory of Ultraman 80 that his face might be fake.
• Furuya asked Lin how he knew so much about Ultraman, and Lin refused to answer.

Lin Xinyi joined Furuya Rei and Kazami to investigate Yamazaki Ken’s murder, while questioning the identity of the disguised Public Security officer and examining the suspicious crime scene. He concluded that the killer might be a minor, someone the police could not afford to cross.

• Lin Xinyi suspected Officer Furuya was an Organization assassin, but Kazami confirmed that Furuya was a genuine Public Security officer using a disguise.
• On the way to the crime scene, Kazami explained that Yamazaki Ken’s wife had been working at an izakaya and could not prove she stayed there all night.
• Lin Xinyi asked about Mrs. Yamazaki’s build, and Furuya described her as tall and physically strong.
• At the villa, Lin Xinyi and Furuya examined signs that the killer had climbed over the yard wall, while Kazami suspected Mrs. Yamazaki.
• Furuya argued that Mrs. Yamazaki would have staged a burglary if she meant to frame an outsider, and Lin Xinyi requested forensic equipment to investigate further.
• Lin Xinyi warned that the killer might be someone they could not afford to cross, then identified that person as a minor.

Lin Xinyi investigated the villa murder and used bloodstain mathematics to estimate the killer’s height. His findings made it highly likely that the murderer was a minor, leaving the officers troubled by the limits of the law.

• Lin Xinyi explained that the killer was likely under sixteen, based on the small footprints, weak hammer blows, reckless attack, and downward stab wound.
• Lin Xinyi entered the villa crime scene and asked why its security door had been left open.
• Lin Xinyi measured bloodstains and had Furuya Rei calculate their impact angles to locate the blood’s source point.
• Lin Xinyi’s calculations suggested the killer was possibly under one and a half meters tall and likely a middle school student.
• Lin Xinyi reasoned that the killer may have attacked with confidence because he knew the law could not hold him criminally responsible.

Lin Xinyi questioned Mrs. Yamazaki about her husband’s death and identified a juvenile offender as a suspect, but the boy had vanished and evidence suggested he never returned home. Lin Xinyi concluded that the suspect might already be dead and ordered a search of nearby secluded areas.

• Mrs. Yamazaki told Lin Xinyi that a fourteen-year-old boy had harassed her and her husband after Mr. Yamazaki sent him to the police for robbing children at knifepoint.
• Lin Xinyi sent Furuya Rei and Kazami Yuya to arrest the boy, then asked Mrs. Yamazaki about her whereabouts and whether her husband owned a gun; she said he had owned one.
• Furuya Rei and Kazami Yuya returned without the suspect, whose parents claimed he was innocent and said he had gone out the previous night without coming home.
• Furuya Rei reported that the boy’s wallet and identification were still at home, leading Lin Xinyi to doubt that he had fled after the murder.
• Lin Xinyi ordered a police-dog search of nearby parks and alleys, saying the suspect might already be dead.

Lin Xinyi reconstructed how Mrs. Yamazaki had shot the teenager who murdered her husband, then brought her to the body in a secluded park. He told her the evidence against her would be easy to find, leaving her accusation of the police unanswered.

• Lin Xinyi explained that the killer had fled over the wall because he encountered Mrs. Yamazaki armed with a gun, and concluded that she had pursued him after the murder.
• Lin Xinyi, Furuya Rei, and Kazami Yuya went with Mrs. Yamazaki to a nearby park, where police had found a teenager shot in the back.
• Lin Xinyi identified the teenager as the likely murderer of Yamazaki Ken based on the hammer, bloody kitchen knife, and blood spatter on his arm.
• Mrs. Yamazaki accused the officers of suspecting her of killing the teenager and demanded that they prove it.
• Lin Xinyi pointed to the footprints and bullet holes near the body and told Mrs. Yamazaki that evidence against her would be easy to find.

Lin Xinyi reconstructed how Mrs. Yamazaki had killed the juvenile offender and offered her a chance to surrender, which she accepted. After the case ended, Lin revealed his anger at the law that exempted children under sixteen from criminal responsibility, while Furuya Rei concluded that Lin was a genuinely good police officer.

• Lin Xinyi explained that Mrs. Yamazaki had pursued the victim in flip-flops, likely retained gunshot residue, and used her husband Yamazaki Ken's registered handgun.
• Lin offered to conceal the evidence and help Mrs. Yamazaki obtain a reduced sentence if she turned herself in, but refused to hide the truth entirely because of his forensic oath.
• Mrs. Yamazaki accepted Lin's offer and was taken to the Tokyo Metropolitan Police Department for detention.
• Lin realized Mrs. Yamazaki had carried her phone because she first intended to call the police after witnessing her husband's murder, then cursed the law exempting children under sixteen from criminal responsibility.
• Furuya Rei told Kazami Yuya that Lin was a genuinely good police officer.

Lin Xinyi took Conan and the Detective Boys to Kinrai Cinema, where he recognized signs that an employee might murder real estate businessman Takada Seiji over the cinema’s sale. His warning prompted Furuhashi to confess and abandon his plan, and the chapter ended with the cinema staff mistaking Lin Xinyi for a sorcerer before he identified himself as a member of the Tokyo Metropolitan Police Department.

• Conan reluctantly joined Lin Xinyi, Haibara Ai, and the Detective Boys for a Gomera movie at Kinrai Cinema.
• At the cinema, Takada Seiji argued with Boss Muramatsu about closing and demolishing the theater, while an employee accused him of driving customers away.
• Lin Xinyi suspected that an employee might kill Takada Seiji and warned Takada to leave, then urged the staff not to resort to murder.
• Furuhashi confessed that he had planned to kill Takada Seiji and said Lin Xinyi’s warning had made him reconsider.
• The staff praised Lin Xinyi as a sorcerer, and he told them he worked for the Tokyo Metropolitan Police Department.

Lin Xinyi prevented Mr. Furuhashi from killing Mr. Takada, and Boss Muramatsu decided to keep and renovate the theater. After the danger passed, Lin Xinyi watched a movie with Haibara Ai and the Detective Boys, leaving Haibara annoyed when he focused on discussing monster movies with Mitsuhiko.

• Lin Xinyi warned the theatergoers that he could detect crimes, and Mr. Furuhashi admitted his mistake and accepted that killing Mr. Takada would not save the theater.
• Boss Muramatsu chose not to sell the theater and promised to fund renovations, while the employees kept watch over Mr. Furuhashi.
• Lin Xinyi found Mr. Takada safe in the theater and joined Haibara Ai and the Detective Boys to watch a movie.
• Mitsuhiko challenged Lin Xinyi about his relationship with Haibara and then discussed Gomera and other monster shows with him.
• Haibara Ai grew cold while Lin Xinyi talked with Mitsuhiko, and Lin stood up to ask the theater to raise the air conditioning.

Lin Xinyi left the theater to address the cold air conditioning and encountered Takada Seiji begging Boss Muramatsu to sell him the cinema because of his debts. Boss Muramatsu refused but offered Takada a place to rest, while Takada blamed Lin Xinyi for predicting his ruin.

• Haibara Ai told Lin Xinyi she was cold, so he wrapped her in his jacket and went to ask the theater staff to raise the temperature.
• Mitsuhiko tried to offer Haibara Ai his jacket, but she sent him to check on Ayumi instead.
• Lin Xinyi found Takada Seiji arguing with Boss Muramatsu, who had decided to renovate the cinema and keep it open.
• Takada Seiji pleaded that loan sharks were threatening his family and that he needed the cinema deal to repay his debts, but Boss Muramatsu refused to sell.
• Boss Muramatsu offered Takada food, drinks, and a place to rest before leaving, while Takada struck the wall and called Lin Xinyi's prediction accurate.
• Lin Xinyi dismissed Takada and walked away, remarking that Takada was at least still alive.

Lin Xinyi and Haibara Ai watched Gomera's Counterattack together, with Haibara settling happily into his arms despite his oblivious attempts at romance. Near the film's end, Mr. Takada confronted Lin Xinyi over his supposed curse, then suddenly collapsed in his seat.

• Lin Xinyi returned to the screening room with popcorn and found Haibara Ai wrapped in his coat while Mitsuhiko sat with Ayumi and Conan.
• Haibara Ai sulked over Lin Xinyi buying separate popcorn buckets, but let him feed her and pull her into his arms as they watched the movie.
• Lin Xinyi and Haibara Ai watched Gomera's Counterattack together, and Haibara asked him not to adjust the cold screening room.
• Haibara Ai noticed Mr. Takada smoking in the back rows, so Lin Xinyi went to ask him to stop.
• Mr. Takada grabbed Lin Xinyi's collar, accused him of cursing him to death, and suddenly collapsed motionless into his seat.

When Mr. Takada collapsed and stopped breathing in a theater, Lin Xinyi tried to revive him but became the prime suspect after a witness described their earlier struggle. Lin kept himself out of the investigation to avoid a conflict of interest and finally assigned the case to Conan.

• Mr. Takada collapsed in the dark theater, and Lin Xinyi performed CPR until emergency personnel took him away in an ambulance.
• A witness said he had seen Lin Xinyi grappling with Mr. Takada and recalled Takada accusing Lin of cursing him before he collapsed.
• The onlookers suspected Lin Xinyi had caused Takada’s death, so Lin called the police and ordered everyone to remain at the scene.
• Lin refused to investigate because he was the prime suspect and a high-ranking Tokyo Metropolitan Police Department official.
• Lin rejected Conan’s offer to investigate secretly, then realized Mouri Ran and Doctor Asai should also avoid the case because they were his students.
• Lin told Conan that the case was his.

Conan and Haibara Ai investigated Mr. Takada’s collapse, which Lin Xinyi believed was most likely an accidental sudden death. Tracing water droplets in the corridor, they concluded that Mr. Takada had been struggling to walk and was already seriously unwell before he entered the screening room.

• Lin Xinyi told Conan that Mr. Takada’s collapse might have been an accidental sudden death, though illness, inhibition death, suicide, or homicide could not yet be ruled out.
• Conan asked about droplets on Mr. Takada’s face and learned from Lin Xinyi that they had been there before the collapse.
• Conan found a trail of water droplets leading toward the screening room and encountered Haibara Ai examining it.
• Conan and Haibara Ai observed that the droplets’ evenly shaped spines and short intervals suggested Mr. Takada had been moving very slowly.
• Haibara Ai deduced that Mr. Takada had already been severely ill before entering the screening room and had used the wall for support as he walked.

Conan and Haibara Ai discovered that Mr. Takada may have suffered a fatal electric shock from a damaged phone charger, rather than dying from an illness. Conan suspected the shock was deliberate, leaving them with a possible murder to investigate.

• Conan followed water droplets to an employee break room and found a damaged, burnt phone charger near a power outlet.
• Haibara Ai explained that an electric shock could kill Mr. Takada without leaving visible Current Marks, especially if his hands were wet.
• Conan and Haibara concluded that Mr. Takada may have touched exposed wires while plugging in the charger, suffered heart damage, and later collapsed.
• Haibara said Mr. Takada's confusion could explain his struggle with Lin Xinyi and that Lin was not responsible for his death.
• Conan told Haibara he suspected someone had deliberately caused Mr. Takada's electrocution.

Conan first concluded that Takada had staged an electrocution suicide to secure insurance money, but reconsidered after spotting a flaw in his deduction. He found Takada's phone in his coat and realized the man may have been charging it while making a call, leaving the cause of death uncertain.

• Conan used the clustered water drops near the outlet to argue that Takada had paused there before deliberately attempting suicide by electrocution.
• Conan told Haibara Ai that Takada's suicide attempt had failed, but he later died from cardiac arrest caused by the shock.
• Conan told Lin Xinyi that Takada's death had been an accident, prompting Haibara Ai to challenge his sudden change of story.
• Conan explained that his earlier deduction had relied on a preconceived impression and asked where Takada's phone was.
• Conan found the phone in Takada's coat and realized Takada may have been charging it while making a call.

Conan reexamined Takada’s apparent electrocution and argued that the evidence did not prove suicide. He concluded that Takada had been crying after his business deal failed, and that his tears may have caused the wet hands and drops that led to the fatal shock.

• Conan found a recent call record and proposed that Takada had answered his daughter while charging his phone, then accidentally suffered an electric shock with wet hands.
• Lin Xinyi noted that the call and water drops could not establish suicide, while Conan said he believed Takada would not abandon his daughter after speaking with her.
• Haibara Ai pointed out that the ten-second call was too brief for the drops to have formed, but Conan showed that Takada had continued texting his daughter afterward.
• Conan and Lin Xinyi questioned why Takada claimed he had been watching a movie when he was actually in the lounge, and Conan observed that his daughter had heard no movie sounds during the call.
• Conan inferred that Takada had been crying and had hung up because he did not want his daughter to hear his sobbing, suggesting the drops on the floor were tears rather than water.

Conan used droplet analysis and a taste test to confirm that Mr. Takada had been crying before he was electrocuted, then reconstructed how he may have returned to the theater after promising his daughter he would come home. The evidence could not establish whether his death was accidental or a staged suicide, and Conan, Lin Xinyi, and Haibara Ai chose to believe he had died while trying to keep that promise.

• Haibara Ai challenged Conan’s deduction that Mr. Takada had been crying and suggested he taste the droplets to check whether they were tears.
• Conan explained how droplet size and fall height could distinguish water from someone’s hands from tears falling from their face.
• Conan confirmed the drops were salty tears and reasoned that Mr. Takada had cried while messaging his daughter, then been electrocuted after wiping his tears and handling his phone charger.
• Conan reconstructed Mr. Takada returning to the screening room to watch Gomera so he could discuss it with his daughter, while Haibara Ai raised the possibility that he had planned to kill himself and disguise it as an accident.
• Lin Xinyi supported Conan’s effort to imagine Mr. Takada’s final moments, said he preferred to believe the death was accidental, and gently patted Haibara Ai’s head.
