Chapter Summaries

Fujino and Hattori watched as two local men invited Ran, Kazuha, and Momiji to go diving, but Momiji turned them down with a pointed, indirect rebuke. The men backed off, and Hattori and Fujino praised Momiji’s Kyoto-style way of reading the room.

• Two local men approached Ran, Kazuha, and Momiji and invited them to go diving after filming.
• Momiji politely declined, explaining that she had come with companions, but the men continued to press her.
• Fujino stopped Hattori Heiji and Conan from intervening, saying Momiji was about to handle the situation herself.
• Momiji hinted that the men were using an outdated tactic to lure girls into an unsafe situation and asked whether they were frivolous people who casually hit on women.
• The two men fell silent, and Hattori Heiji and Fujino praised Momiji’s ability to deal with them.

Fujino and Hattori Heiji stepped in when two men harassed Ran, Kazuha, and Momiji aboard the ship, then negotiated more pay from director Takefumi Masao to stay on the program. The captain and a white-haired man warned that the Messenger of Gusou would come for the Mabui of anyone stranded on the island after sunset.

• Fujino and Hattori Heiji told the two men to stop pestering the girls, while Hattori called Kazuha a childhood friend he had no relationship with.
• A short-haired woman identified Fujino and Hattori as the program’s featured detectives, and Takefumi Masao described their roles in the show.
• Fujino threatened to leave the program unless Takefumi Masao paid more, and Takefumi agreed to give each detective another 250,000 yen.
• The white-haired uncle warned that the Messenger of Gusou would come for the Mabui of anyone stranded on the island after sunset, and asked Captain Shimoji to confirm it.

Fujino, Conan, and Hattori turned two punks’ fake underworld legend against them, while Hattori earned a black eye after guessing a woman’s swimsuit. Fujino then contacted Hiroki Sawada, who identified the island’s mayor as Kinjō Hyōgo and began sharing what he had found about him.

• Two punks told Ran, Kazuha, and Momiji a made-up legend about a messenger from hell, and Fujino and Conan linked it to the real Xiao Hei.
• Conan, Hattori, and Fujino frightened the punks by describing Xiao Hei’s attacks, while the blonde woman complained that their story had spoiled her plans to swim.
• Hattori guessed that the blonde woman would wear a white high-cut bikini, so Kazuha punched him and left him with a bruised eye.
• Conan and Hattori discussed why Fujino had reported Hattori’s swimsuit guessing, and Hattori realized it was inappropriate to do that in front of a child.
• Fujino called Hiroki Sawada, who confirmed the ship’s satellite equipment could maintain their connection and said the island’s mayor was Kinjō Hyōgo.

Fujino recalled the truth behind the old robbery and murder case as his group arrived at Ghost Turtle Island with several people tied to the crime. On the island, Hattori and Conan bickered over a woman’s diving suit while Fujino teased Hattori about Kazuha.

• Hiroki Sawada explained that robbers had kidnapped the Kinjo Family’s daughter, later stolen a golden folding screen, and murdered the family maid.
• Fujino remembered that Mayor Kinjo’s daughter had arranged her own kidnapping and later returned with the robbers to steal her stepfather’s heirloom, during which the maid was killed.
• Fujino identified Kanahiko Daito, Ie Taira, Shinro Ikema, Yoshitsugu Kume, and Takashi Shimoji among the boat’s passengers and recalled their connections to the old crime.
• Fujino realized that Takashi Shimoji had murdered the maid and that Kanahiko Daito had followed the group to avenge her.
• Ie Taira dove into the water in a diving suit, and Conan corrected Hattori Heiji’s guess about her swimwear.
• Fujino teased Hattori Heiji for staring at Ie, and Toyama Kazuha called Hattori back to work.

Fujino, Hattori Heiji, and the others investigated a deserted villa on Ghost Turtle Island, where a year-old starvation death and a cryptic inscription had become the focus of a program. The group split up to search the island, while Hattori remained to puzzle over the inscription and wondered whether Fujino had given up on solving it.

• Hattori Heiji and Takefumi Masao examined the inscription, and Takefumi explained that a body had been found at the villa after a typhoon and had died of starvation.
• Ooka Momiji and Kazuha wondered about the inscription and the villa’s owner, and Ie Taira explained that Mr. Kinjo’s family had abandoned the villa after a typhoon damaged it.
• Kanahiko Daito said he had visited the island two years earlier, and Hattori Heiji inferred that the nearby waters had strong currents from the local fish and seagulls.
• Kanahiko Daito recalled that the two young men used to dive on the island, but they said their friends had stopped coming after the body was found.
• Takefumi Masao sent the group to search nearby while he, Fujino, and Hattori Heiji stayed at the villa to discuss the program.
• Fujino left to explore the island with the others, telling Hattori Heiji to stay behind, and Hattori wondered whether Fujino had discovered a weakness in solving codes.

Fujino followed Ie Taira and Kanahiko Daito into the forest, where he stopped Daito from strangling her. Daito explained his revenge plan and revealed that Ie Taira was Kinjo Koto, the former mistress he had served.

• Hattori Heiji worried that Fujino had already understood the ciphers, while Conan and Kazuha assumed Heiji was caught up in competing with him.
• Fujino tracked Ie Taira and Kanahiko Daito into the forest and watched them approach a small boat hiding a box.
• Daito strangled Ie Taira, believing she was one of the bandits who had killed his fiancée, Matsumoto Yoshiko.
• Fujino cut the rope and kicked Daito away, then confirmed that Ie Taira had only passed out.
• Daito told Fujino that he had used the Urashima Taro cipher to lure the bandits and revealed that Ie Taira was formerly Kinjo Koto.

Fujino persuaded Kanahiko Daito to reconsider his revenge and identify who had truly killed Yoshiko, then proposed using Daito’s plan to recognize the old bandit gang members aboard the ship. After returning from the island, Fujino found Conan and Hattori still struggling with the code.

• Kanahiko Daito suspected Koto had planned the robbery, but Fujino slapped him and urged him to pursue the truth about Yoshiko’s murder.
• Fujino and Daito concluded that Takashi Shimoji had killed Yoshiko on his own, while Koto had likely planned only to steal the folding screen.
• Fujino stopped Daito from killing Shimoji and proposed using Daito’s plan to identify the former bandit gang members on the ship.
• Fujino and Daito returned from exploring the island and found Conan and Hattori still trying to decipher the code.

When Miss Taira went missing, Fujino searched the dangerous waters and found an old anchor that appeared to have been deliberately sunk. The anchor’s age connected it to the mayor of Kinjo’s past, and Fujino suggested it might point to the hiding place of a stolen folding screen.

• Ran and Kazuha wondered why Miss Taira had not returned, prompting Hattori Heiji and Conan to rush outside to look for her.
• Fujino and the others searched the shore but could not find Miss Taira, so Fujino decided to check the place where she had been diving.
• Fujino swam into the sea despite Hattori Heiji and Ooka Momiji’s concerns, then returned with an anchor that had been underwater for years.
• Fujino said the anchor looked deliberately cut and sunk, and the subcultural youth connected its age to events at the mayor of Kinjo’s house four and five years earlier.
• Kazuha wondered whether the kidnapped girl had been buried on the island, and Fujino suggested the stolen folding screen might be hidden where he found the anchor.
• Captain Takashi Shimoji and Yoshitsugu Kume reacted with surprise to Fujino’s suggestion.

Fujino reasoned that the missing folding screen might have washed ashore on Ghost Turtle Island, while the group searched for the missing Miss Ie Taira. When they returned to the pier, they discovered their boat was gone, leaving them stranded as Kanahiko Daito suspected someone else was hiding on the island.

• Fujino suggested that a robber who found the folding screen on the island had hidden it there and left clues before dying.
• Momiji, Conan, and Hattori Heiji discussed Fujino’s theory, with Hattori doubting his intuition despite admitting the anchor was suspicious.
• Fujino proposed that Miss Taira might be injured and trapped in the forest, but the group decided to return to the boat for flashlights and call for help.
• The group reached the pier and found that their boat had disappeared.
• Takashi Shimoji said someone must have raised the anchor and sailed the boat away, and Kanahiko Daito speculated that the robbers might be hiding on the island and planning to kill them.

After their boat disappeared, the stranded group took shelter in a dilapidated villa and worried that no one would come looking for them. Fujino tried to reassure them by revealing a black-peach-wood sword he claimed could ward off evil spirits.

• Takefumi admitted he had concealed the scouting trip from the producer, leaving the group unsure whether anyone knew they were missing.
• Kazuha and Ran suggested that Mouri would come looking for them, though Ran admitted he might be drinking.
• The group explored the rundown villa and settled in a windowless dining room as night fell.
• Ran and Kazuha speculated that the Messenger of Gusou had stolen their boat, while Hattori dismissed their ghost story.
• Fujino produced a black-peach-wood sword named Okamoto Peach Blossom 0.01 and said it could suppress evil spirits.

Fujino and Kanahiko Daito used an ashtray to suggest that bandits might still be hiding on the island, prompting the group to search the house. On the second floor, Yoshitsugu Kume and Takashi Shimoji argued about Koto and the stolen folding screen before a figure with a Wooden Sword confronted them as the bandit gang’s true murderer.

• Kanahiko Daito found a teacup used as an ashtray, and Fujino pointed out that multiple cigarette butts and undried water suggested someone had been there recently.
• Fujino proposed that the group search the house again, splitting everyone between the first and second floors.
• Yoshitsugu Kume and Takashi Shimoji searched together and discussed whether Koto had taken the folding screen and betrayed the bandits.
• A figure in a white shirt carrying a Wooden Sword entered and declared that they had found the bandit gang’s true murderer.

Fujino caught Takashi Shimoji and Yoshitsugu Kume admitting that they had robbed a house and murdered a maid, then faced them when they decided to kill him and silence the witnesses. He overwhelmed Takashi Shimoji and turned toward Yoshitsugu Kume, who finally understood why Fujino had handed them daggers.

• Fujino revealed that he had recorded Takashi Shimoji and Yoshitsugu Kume confessing to the robbery and murder.
• Takashi Shimoji persuaded Yoshitsugu Kume to kill Fujino and the witnesses, then blame Miss Kaneshiro.
• Fujino picked up a Wooden Sword as Takashi Shimoji attacked him with a dagger.
• Fujino struck Takashi Shimoji, broke his arm and legs, and took his dagger.
• Fujino approached Yoshitsugu Kume, who trembled and tried to drop his dagger.

Fujino revealed that Kume and Takashi Shimoji were members of the gang that robbed Mayor Kinjo’s home and explained how he and Daito had staged events to expose them. The group learned that Koto was still on the island and that Daito had moved their boat, which was expected to return soon.

• Conan and Hattori Heiji rushed upstairs and found Fujino binding and treating the injured Kume and Takashi Shimoji.
• Fujino played a recording showing that Kume and Shimoji were members of the gang that robbed Mayor Kinjo’s home.
• Fujino explained that Koto was not Kinjo’s biological daughter and had robbed her own home with the two men.
• Fujino revealed that the supposed second gang and the cigarette butts had been fabricated by Daito, who had been the Kinjo family’s butler.
• Fujino said he had knocked Koto unconscious and hidden her, while Daito had set their boat to return on automatic cruise.
• Conan and Hattori pointed out clues that Daito knew the house and had helped plan the scheme.

Fujino captured the bandits, then piloted the group’s yacht back from Ghost Turtle Island after Conan and the others admitted they could not steer it. After the case and production wrapped up, summer vacation continued with Conan doing radio calisthenics at Teitan Elementary and complaining about the Black Organization.

• Kazuha confronted Hattori for keeping quiet about Fujino’s plan, while Kanahiko Daito gave up on taking revenge against the crippled captain.
• Fujino released Ie Taira and the group returned to Ghost Turtle Island, where they struggled to find someone to pilot their yacht.
• Conan said he had learned to pilot a boat in Hawaii, but Fujino took the helm and guided everyone safely back.
• The production crew ended its program, and Mayor Kinjo paid the promised fee after his daughter and family heirloom were found.
• Conan joined Genta, Ayumi, Ai Haibara, and Professor Agasa for summer radio calisthenics, then noticed Fujino doing the exercises lazily.

The Detective Boys visited Mitsuhiko's house after he missed radio calisthenics, only to learn he had claimed he was going camping. They found no note and discovered his wallet was missing, leaving them to wonder where he had gone.

• During radio calisthenics, Genta and Ayumi wondered why Mitsuhiko and Asami had been absent, and Haibara guessed Mitsuhiko might be on a date.
• Professor Agasa led the group to Mitsuhiko's house, where Asami Tsuburaya said Mitsuhiko had planned to go camping and packed bamboo leaf dumplings.
• Asami invited the group to search Mitsuhiko's room, but they found no note and discovered his wallet was gone.
• Conan reasoned that Mitsuhiko might have gone somewhere far away, while Genta suggested he had run away from home.
• Asami reacted with excitement at the possibility that Mitsuhiko had run away.

Fujino and the Detective Boys investigated Mitsuhiko's disappearance, first suspecting a date and then learning that he had been searching for fireflies. A flower-shop girl recalled seeing someone resembling Mitsuhiko board a bus that morning, and the sunscreen scent suggested it really was him.

• Asami Tsuburaya guessed that Mitsuhiko had gone on a seaside date with a girl he helped at a flower shop and gave Fujino her phone number before leaving for piano lessons.
• Fujino and the Detective Boys went to the flower shop, where a girl said Mitsuhiko had been scolded by two men who forbade him from taking something associated with warlords.
• Fujino recalled that Mitsuhiko had been secretly following the two men to find fireflies and had messaged him that morning that his search was going smoothly.
• The flower-shop girl remembered seeing someone resembling Mitsuhiko board a bus after morning calisthenics, wearing a low hat and carrying a bag.
• Conan asked about the strange lemon-like scent, and Fujino and Ai Haibara concluded it was likely Asami's sunscreen and that the passenger had been Mitsuhiko.

Fujino and the Detective Boys followed Mitsuhiko’s trail into the mountains of Gunma, where they encountered Officer Yamamura Misao searching for an escaped serial killer. Yamamura admitted enough to reveal that he had accidentally let the suspect Numabuchi Kiichiro escape, while Mitsuhiko remained missing nearby.

• Fujino gave the girl at the flower shop an autograph, and the group followed clues from the bus stop to Beika Station and then to Gunma.
• Conan tracked Mitsuhiko’s Detective Badge signal into the forest, while the group wondered why Mitsuhiko had gone there alone.
• The group encountered Yamamura Misao and learned that police were searching the woods for escaped serial killer Numabuchi Kiichiro.
• Genta, Ayumi, and Ai Haibara pointed out that Yamamura had accidentally revealed he was the colleague who let Numabuchi escape.

Conan and the others told Yamamura Misao that Mitsuhiko had entered the forest where Numabuchi Kiichiro was hiding, but Misao dismissed their claims and gadgets as childish make-believe. After a senior officer ordered Misao to help search for Numabuchi, Professor Agasa confirmed that his inventions were real, leaving Misao finally unsure whether Fujino was a genuine police consultant.

• Conan recognized the name Numabuchi Kiichiro and realized Mitsuhiko was in danger, then explained that the group had tracked him into the forest.
• Yamamura Misao dismissed the Detective Badge and tracking glasses as toys, and the glasses ran out of power while he inspected them.
• Fujino showed Misao his police ID, but Misao mistook it for part of the group's make-believe detective gear.
• A bald officer ordered Misao to take the children somewhere safe and then join the search for Numabuchi, who had escaped while Misao was on duty.
• Ayumi demonstrated her Detective Watch, and Professor Agasa confirmed that he had invented the children's detective gadgets, making Misao question whether Fujino was really a consultant.

Fujino revealed his identity as the High School Detective and persuaded Yamamura Misao to help search for Numabuchi Kiichiro, who might find Mitsuhiko. The group continued searching as Fujino suspected Mitsuhiko was lost, while Conan teased Ai Haibara about reading news about Fujino.

• Yamamura Misao panicked about the consequences of his mistakes, and Fujino said they could solve the problem by catching Numabuchi Kiichiro before he reached Mitsuhiko.
• Ayumi and Genta praised Fujino, prompting Yamamura Misao to recognize him as the High School Detective Fujino Doji and ask for his help.
• Fujino told Yamamura Misao he had concealed his identity to spare him harsher punishment, and the two formed a friendly alliance.
• Fujino, Yamamura, Professor Agasa, the children, and Ai Haibara searched the forest for Mitsuhiko and Numabuchi Kiichiro as the sky darkened.
• Fujino said Mitsuhiko’s moving marker suggested he was lost rather than dead, and Conan teased Ai Haibara about mostly reading news about Fujino.

Fujino reflected on his old suspicions about Numabuchi Kiichiro while the group searched a forest for a supposedly buried victim. As Fujino noticed a figure watching them from a tree, he recognized the lurking Numabuchi.

• Haibara rebuffed Conan’s remark about her looking at Shinichi, leaving him feeling hurt.
• Fujino recalled investigating Numabuchi in Kyoto and eventually concluding that he had not committed the murders.
• Yamamura explained that Numabuchi had claimed to kill a fourth victim buried in Gunma, prompting his transfer before he escaped.
• Ayumi stepped into a stream, and Yamamura reminisced about playing in the forest with a close childhood friend.
• Yamamura asked about Fujino’s watch, and Fujino called his expensive Rolex perfectly ordinary rather than reveal its price.
• Fujino sensed Numabuchi nearby and spotted him hiding in a tree, where Numabuchi also noticed Fujino.
