After Miss Taira failed to return to the ship, Jiang Xia, Conan, Hattori Heiji, Mouri Ran, Suzuki Sonoko, and Curacao searched the island and found her strangled body on the shore. Hattori Heiji deduced that the killer had moved the body after the tide began to recede, raising the possibility that the murderer was not among the ship’s crew.

After the group realized the Captain may have helped the killer escape, they found themselves stranded on Ghost Turtle Island with no rescue expected until the next day.

The Deputy Captain discovered a cup full of fresh cigarette butts, suggesting several people had met in the room before the group arrived.

• Hattori Heiji estimated that the shell-covered ship anchor had been underwater for four or five years, prompting the long-haired man to recall the misfortunes that began around then.
• The long-haired man and the blond man explained that Mayor Jincheng’s daughter Xiao Du had been kidnapped and his Gold Folding Screen stolen, but the mayor refused to pay ransom and both disappeared.
• The program director recounted the mayor’s other losses, including his wife, a maid, and his butler, as well as a corpse found on the island and Taira’s recent murder.
• Curacao suggested that the word “princess” on the corpse might refer to Xiao Du, and Mouri Ran and Suzuki Sonoko wondered if Xiao Du’s spirit was the Underworld Messenger.
• The Deputy Captain dismissed the supernatural suspicions and described the legend’s small-knife protection, then found a water-filled cup containing cigarette butts of several brands.
• Hattori Heiji inspected the still-wet cigarette butts and concluded that several people had gathered in the room before the group arrived.

The group suspected that criminals were hiding in the abandoned villa and split up to search it. Jiang Xia opened the last room on the First Floor, but it was empty, leaving the group on edge and the source of the Killing Intent unexplained.

• The Deputy Captain suggested that the people in the villa might be the criminals who had killed two people and were hiding from capture.

• Jiang Xia opened the last room abruptly, startling Curacao and Hattori Heiji, but the room was empty.

Jiang Xia and the others searched the mayor’s abandoned home, where photographs and carvings revealed details about Mayor Jincheng’s family and the missing Xiao Du. The group connected Xiao Du to the earlier “princess” clue but found that the marks on a doorframe were only childhood height records.

• Jiang Xia, Hattori Heiji, and the director entered the mayor’s bedroom and discovered a hidden photograph of Mayor Jincheng with his daughter, Xiao Du.
• The director explained that Xiao Du had been kidnapped five years earlier and that his cousin, a maid, had been killed during the robbery at the mayor’s home four years earlier.
• The director revealed that Chikan was Xiao Du’s cousin because their mothers were sisters.
• Jiang Xia identified the building in the photograph as the mayor’s castle-like home, and Suzuki Sonoko linked Xiao Du to the “princess” clue found beside a corpse.
• Hattori Heiji read the carvings on a doorframe as childhood height markings labeled “Chioni,” “Kachan,” and “me.”

Jiang Xia and the others investigated the island house, finding childhood room labels and strange drawings before a scream sent them upstairs. They discovered Kume had been frightened by a gloomy portrait of the Mayor’s daughter, Miss Xiao Du.

• Conan noticed the room labels “Mama’s Room” and “Kachan’s Room,” and Jiang Xia suggested Kachan might refer to someone whose name contained “Ka.”
• Conan identified another room as Chioni’s, while Suzuki Sonoko and Mouri Ran examined the strange drawings on the doors.
• Hattori Heiji photographed the clues and said they could ask the Mayor about Kachan and Chioni after the rescue team arrived.
• A scream from the second floor sent Jiang Xia, Hattori Heiji, and the others upstairs, where they found Kume scrambling away from a room.
• The black-haired boatman explained that Kume had been startled by a portrait of the Mayor’s daughter, Miss Xiao Du.

Jiang Xia and the others uncovered several connections between the island’s guests and the Mayor’s family while they waited for rescue. A boat returned to the pier in the dark, but Jiang Xia stopped Mouri Ran and Suzuki Sonoko from approaching after noticing its lights were off.

• Jiang Xia and the others learned that the long-haired man was the Mayor’s Wife’s nephew, Kume had attended school with Miss Xiao Du, and Daito claimed to have been the Mayor’s Wife’s childhood sweetheart.
• The long-haired man revealed that Miss Xiao Du had been abducted five years earlier and was presumed dead, then the group gathered in the dining room to wait for rescue.
• Conan and the others worried that Mouri might not notice they were missing, while the long-haired man blamed the Captain for leaving them stranded.
• A loud crash outside made Mouri Ran and Suzuki Sonoko think rescue had arrived, and they hurried toward a boat moored at the pier.
• Jiang Xia pulled Mouri Ran and Suzuki Sonoko back when he saw the boat had no lights, and the long-haired man recognized it as the Captain’s boat.

Jiang Xia and the others discovered the Captain’s bloody corpse hanging from the boat and realized the murderer had used the boat’s Autopilot System to return it to the island. Hattori Heiji narrowed the suspects to the locals who had been aboard, then the Deputy Captain challenged Heiji’s earlier claim about when Miss Taira was killed.

• Jiang Xia led the group to the boat, where Hattori Heiji’s flashlight revealed the Captain’s corpse hanging from the hull beside the words “I am a Messenger of the Underworld.”
• Hattori Heiji examined the Captain’s body and concluded that the killer had beaten him repeatedly after death.
• Jiang Xia explained that the murderer had used the boat’s Autopilot System and the island’s Coral reefs to guide it back to the pier.
• Jiang Xia and Hattori Heiji told the crew that the murderer could be any local who had stayed behind after the others left the boat to search for Miss Taira.
• The Deputy Captain accused the three crew members of possibly returning to the boat after everyone else left, then questioned Hattori Heiji’s earlier estimate of when Miss Taira had died.

After the group found the Captain’s corpse, Jiang Xia said the damaged boat could not safely take them back, so they planned to stay together until rescue arrived. Hattori Heiji and Conan privately discussed clues suggesting the victims were searching the seabed and that the island’s old labels might reveal a connection to Mayor Jincheng.

• The blond-haired man and the Production Team director argued that the matching messages linked Miss Taira’s murder to the Captain’s, while Hattori Heiji privately regretted his earlier deduction.
• Jiang Xia said the boat had little Fuel and its radio and lights were destroyed, so the group returned to the Villa to await rescue.
• Hattori Heiji warned everyone that the killer might strike again, and they agreed to remain together in the dining room overnight.
• Hattori Heiji and Conan privately noted that Miss Taira and the Captain appeared to be searching for something on the seabed, possibly near the old anchor.
• Hattori Heiji and Conan discussed children’s labels beneath the Chairs, including “kaneshirosan,” and wondered why Miss Xiao Du had used that name for Mayor Jincheng instead of “Papa.”

Conan and Hattori Heiji told Jiang Xia about the names written beneath the chairs, then raced him to find evidence. While the others waited for food, Jiang Xia confronted Curacao about her secret mission to recover a stolen Gold Folding Screen, leaving her stunned and suspicious of Rum.

• Conan and Hattori Heiji told Jiang Xia that three chairs bore the names “me,” “Mom,” and “Mr. Kinjo,” while Kachan and Chioni’s names were absent.
• Jiang Xia started to name the killer, but Hattori Heiji stopped him and asked him to search for evidence while the Detectives continued deducing.
• Mouri Ran and Suzuki Sonoko went to look for food in the kitchen as the other crew members stayed inside the Villa.
• Jiang Xia told Curacao that she had come to Okinawa to recover the Gold Folding Screen stolen by the kidnappers four years ago.
• Curacao realized Jiang Xia could know about her mission only if Rum had revealed it.

Curacao struggled with whether to accept Jiang Xia’s offer to locate the Gold Folding Screen, which contained a code sought by the Organization, and finally agreed. Meanwhile, Mouri Ran and Suzuki Sonoko mistook the returning Hattori Heiji for a water ghost, and the detectives discovered names written beneath stools.

• Curacao realized the Organization wanted a code hidden on the Gold Folding Screen and reluctantly accepted Jiang Xia’s offer to help her reach it.
• Mouri Ran and Suzuki Sonoko searched the kitchen, found only expired snacks, and heard wet footsteps approaching.
• Jiang Xia and the soaked Hattori Heiji entered the kitchen, startling the girls, who had put knives in their mouths to ward off a water ghost.
• Hattori Heiji explained that he had searched the reefs for the missing luggage, and Conan and Hattori noticed kana written under two stools.
