• The police arrested Hatamoto Ichiro after the yacht docked, and Jiang Xia and his classmates set off for Mermaid Island.
• Jiang Xia noticed a woman aboard the Mermaid Island boat who carried a trace of Killing Intent that smelled like Sweet and Sour Fish.

Hattori Heiji reunited with his client Kadowaki Saori on the boat, where she explained that her missing Dugong Arrow might bring a Mermaid’s curse. Jiang Xia sensed powerful killing intent from Shimabukuro Kimie as she dismissed Saori’s belief in Mermaids and recalled a mysterious incident from three years earlier.

• Hattori Heiji recognized Kadowaki Saori’s voice, returned her request letter and money, and asked about her problem.
• Kadowaki Saori explained that she had lost a Dugong Arrow and feared the Mermaid would punish her.
• Shimabukuro Kimie admitted that she had invented the curse story to discourage people from demanding compensation for the arrows.
• Kadowaki Saori insisted that Mermaid bones burned in a warehouse three years earlier proved Mermaids existed.
• Jiang Xia noticed Shimabukuro Kimie’s killing intent intensify and suppressed his hunger for it with a Ghost Mint.

Shimabukuro Kimie’s memories revealed that Kadowaki Saori and her friends had accidentally killed Kimie’s mother, who had played the Elder, and that Kimie now planned to murder them. At the Shrine, Jiang Xia found a powerful Ghost Fetus aura and was attacked by a person-sized Mermaid Ghost.

• Shimabukuro Kimie remembered how Kadowaki Saori and her friends set fire to the storeroom, killing Shimabukuro Naoko, and how Kimie took over the Elder’s disguise.
• Kadowaki Saori confessed to Kimie that she had burned the Mermaid and asked for an arrow and the location of the bones so she could become immortal, prompting Kimie to plan to kill her and her friends.

• Hattori Heiji returned Kadowaki Saori’s commission fee, and Kimie took Saori home while Jiang Xia sensed a powerful Ghost Fetus aura on the island.
• Jiang Xia followed the aura to the Shrine and dodged a translucent tail that swept at him from a person-sized Mermaid Ghost perched atop the Torii.

Jiang Xia captured the Mermaid Ghost and negotiated with her by promising to grant one reasonable wish in exchange for a Contract. She wished for him to kill the three people who had burned her, but Jiang Xia urged her to take revenge herself, leaving her uncertain because she could barely affect the living world.

• Jiang Xia grabbed the Mermaid Ghost by her tail, dragged her through the Torii, and carried her to the woods to avoid being seen.
• Jiang Xia identified the Mermaid Ghost as Shimabukuro Naoko and persuaded her to listen by warning that her daughter, the mermaid festival, and the island were in danger.
• Jiang Xia explained Shimabukuro Kimie's plan and offered to grant one reasonable wish if the Mermaid Ghost willingly signed a Contract afterward.
• The Mermaid Ghost decided to ask Jiang Xia to kill the three people who had set the fire that killed her.
• Jiang Xia questioned why the Mermaid Ghost would not kill the arsonists herself, and she hesitated after realizing she could barely affect physical objects.

Jiang Xia helped the Mermaid use Ghost Mint so she could frighten Kadowaki Saori into fleeing, while the Mermaid grew eager to stay near his supply of it. Kadowaki escaped into the sea, where she discovered that the Mermaid stopped at the shore, leaving her to wonder why the Ghost avoided the water.

• Jiang Xia warned the Mermaid to make Kadowaki Saori's death look like an accident and gave her Ghost Mint to act.
• The Mermaid appeared in Kadowaki Saori's bathtub and terrified her into fleeing through the front door.
• The Mermaid enjoyed the Killing Intent from the Ghost Mint and decided that staying close to Jiang Xia and his supply was worthwhile.
• Kadowaki tried to reach the Shrine, but the Mermaid appeared on a bridge and chased her until she fell into the sea.
• The Mermaid stopped at the shore and avoided the waves, prompting Kadowaki to wonder whether she was a freshwater fish.

Kadowaki Saori tried to escape the mermaid, but Jiang Xia and the mermaid cornered her at sea and retrieved her phone before she drowned. The next morning, Shimabukuro Kimie prepared to kill Kadowaki Saori, then noticed something caught among the shoreline rocks.

• Kadowaki Saori tested whether seawater harmed the mermaid, then fled in a small boat toward a nearby island.
• The mermaid and Jiang Xia overturned Kadowaki Saori's boat, and she confessed that she had lost the arrow and had hurt the mermaid three years earlier.
• Jiang Xia demanded Kadowaki Saori's phone password, unlocked the phone, and passed it to the mermaid; Kadowaki Saori drowned after realizing the two demons were accomplices.
• Jiang Xia retrieved the phone and flew back to Mermaid Island with the mermaid.
• Shimabukuro Kimie prepared a rope to kill Kadowaki Saori, cleaned the Shrine, and noticed something wedged among the rocks by the shore.

Shimabukuro Kimie hid Kadowaki Saori’s body and continued her plan to kill the people responsible for her mother’s death. At the Mermaid Festival, she avoided involving Jiang Xia and the other high school students, while arranging for her former friends to win two Dugong Arrows.

• Shimabukuro Kimie found Kadowaki Saori dead among the rocks, then secretly hid the corpse and decided to continue her plan.
• Jiang Xia learned about the body from his ghosts and chose not to interfere, reasoning that Saori’s death could be treated as an accident.

• Shimabukuro Kimie studied Jiang Xia’s solved cases but decided not to involve the high school students in her plan.
• Disguised as the elderly fate, Shimabukuro Kimie announced the winning numbers, avoiding the girls’ tickets and making Kaihara Nami a winner.
• Shimabukuro Kimie returned as a Shrine Maiden and directed the crowd to Mermaid Falls for the Dugong Arrow ceremony.

Jiang Xia used the Mist Tengu puppet to interfere with Shimabukuro Kimie’s plan to kill Kaihara Nami, and Nami died in the river anyway. Kimie suspected that the mermaid that killed Nami might have been her mother, while Jiang Xia collected Kimie’s unused killing intent.

• Jiang Xia sent the Mist Tengu puppet into the mountains above Mermaid Waterfall while Shimabukuro Kimie arranged to meet Kaihara Nami there.
• Shimabukuro Kimie approached Kaihara Nami with a rope, intending to strangle her, but a sudden wave swept Nami into the river.
• Kaihara Nami became tangled in the current and safety rope, which wound around her neck before she fell from the cliff and died in front of the waterfall.
• Shimabukuro Kimie wondered whether a mermaid had killed Nami and whether it was her mother, who had also been connected to Kadowaki Saori’s death.
• Jiang Xia switched into Xiao Bai’s puppet, and the Mist Tengu collected the killing intent Shimabukuro Kimie had not been able to use.

Jiang Xia disposed of the life buoy Shimabukuro Kimie had prepared and arranged for Kadowaki Saori’s corpse to be returned to the sea. At the festival, Kaihara Nami’s body appeared hanging above Mermaid Falls, and Jiang Xia joined Conan and Hattori Heiji in investigating the scene with Shimabukuro Kimie as their guide.

• The Mermaid tried to destroy the life buoy, but Jiang Xia took it, deflated it, and stored it away.
• Jiang Xia found Kadowaki Saori’s corpse hidden in the Shrine and had the Mermaid dispose of it at sea.
• At the festival, Shimabukuro Kimie gave sacred arrows to Kuroe Nao and another winner, while Kaihara Nami failed to appear.
• Conan and Hattori Heiji worried that something had happened to the missing winner, recalling earlier deaths during their journey.
• As the fireworks began, the crowd spotted Kaihara Nami hanging by a rope above Mermaid Falls.
• Jiang Xia, Conan, and Hattori Heiji returned to the riverbank with Shimabukuro Kimie to investigate.

Jiang Xia, Hattori Heiji, and Conan recovered Kaihara Nami’s body and suspected her death was a murder connected to the Mermaid Festival and the Mermaid Grave. With the police delayed by rough seas, they agreed to investigate the island the next day, while Hattori resolved to treat Jiang Xia as a helpful reference rather than a rival.

• Jiang Xia and Hattori Heiji hauled Kaihara Nami’s body from the river, and they and Conan examined the tangled rope around her neck.
• Kuroe Nao said Nami had likely rushed into the mountain after mistaking something near the waterfall for a sign from the mermaid, and she mentioned the Mermaid Grave.
• Jiang Xia noticed the Dugong Arrow in Kuroe Nao’s hand and thought it was time for the arrow to break.
• After the group carried Nami’s body back beneath the waterfall, the women called the police, but rough seas delayed their arrival.
• Hattori Heiji and Conan joined Jiang Xia to discuss the case, and Hattori decided to stop treating Jiang Xia as a deduction rival.
• The detectives concluded that they needed to learn more about the Mermaid Grave and planned to ask the islanders about it the next day.

Kuroe Nao discovered that her Dugong Arrow had broken and received a message claiming the Mermaid’s grave had been found, while Jiang Xia secretly sent the message using Kadowaki Saori’s phone. Hattori Heiji and Toyama Kazuha found a grave in the Back Mountain, where Heiji knocked its stone toward a cliff, and Jiang Xia heard a scream that sounded like Kazuha.

• Kuroe Nao woke from a nightmare, found her Dugong Arrow broken, and learned from Shimabukuro Kimie that she could not get a replacement.
• Jiang Xia sent Kuroe Nao a message from Kadowaki Saori’s phone claiming that the Mermaid’s grave had been found, then discarded the phone in the sea.
• Jiang Xia questioned Kadowaki’s Father, who revealed that he had sold Kadowaki Saori’s arrow to a tourist for one million, before leaving to check the neighbors’ houses.
• Hattori Heiji and Toyama Kazuha visited the longevity oracle, who warned them that people seeking the Mermaid’s grave had been cursed.
• Hattori Heiji and Toyama Kazuha followed a figure into the Back Mountain and found a small grave, where Heiji knocked the grave stone toward a hidden cliff.
• Jiang Xia heard a distant scream that sounded like Toyama Kazuha.

Jiang Xia found Hattori Heiji and Toyama Kazuha hanging from a failing tree below a cliff and secretly reinforced it with Puppet Clay. As he looked for a way to pull them up, Kuroe Nao fled the Mermaid and ran past him toward the cliff edge.

• Jiang Xia discovered Hattori Heiji and Toyama Kazuha dangling from a tree after they fell from the cliff, and Toyama Kazuha urged Hattori Heiji to let go.
• Hattori Heiji refused to release Toyama Kazuha, and she grabbed him tightly, declaring that they should die together.
• Jiang Xia reinforced the tree with Puppet Clay and told Hattori Heiji and Toyama Kazuha he would find something to pull them up with.
• Kuroe Nao fled the Mermaid, spotted Jiang Xia, and rushed past him as he warned her that a cliff lay behind him.
• Kuroe Nao stepped into empty air at the cliff edge.

Jiang Xia, Hattori Heiji, and Toyama Kazuha survived a fall from the cliff, but Kuroe Nao died below. Trapped on a sturdy tree, the three received a rope from Anonymous, whom Jiang Xia was controlling as a puppet.

• Jiang Xia reached for Kuroe Nao, but she fell past the trees and died on the rocky riverbank.
• Jiang Xia slipped from the cliff and landed on a tree trunk, then secretly reinforced it with Puppet Clay.
• Jiang Xia pulled Hattori Heiji and Toyama Kazuha onto the trunk and acted as though Kuroe Nao's death had left him devastated.
• Toyama Kazuha failed to call for help because the island had poor signal, while Hattori Heiji searched for a way to climb back up.
• Anonymous appeared at the cliff edge, then tossed down a hemp rope before disappearing into the woods.

Hattori Heiji, Jiang Xia, and Toyama Kazuha escaped the Back Mountain and returned to the inn after Kuroe Nao’s fall, while the storm delayed the police search. Jiang Xia contracted the Mermaid, whose new mark strengthened his other Ghosts but left the Mermaid unable to move independently, and he ended the chapter trying to make Mist Tengu grow larger.

• Hattori Heiji climbed the cliff first and found Anonymous had already left, then helped Jiang Xia and Toyama Kazuha climb up.
• Toyama Kazuha secured Jiang Xia with a rope before he climbed, and she followed him to the top of the cliff.
• The three students returned to the inhabited area, where Hattori Heiji called the police and reported Kuroe Nao’s death, but rough seas delayed their arrival.
• Jiang Xia returned to his room, contracted the Mermaid, and watched the energy strengthen his other Ghosts while reducing the Mermaid’s ability to move independently.
• The Mermaid shrank to the size of a Ghost Fetus and clung to the Ghost Mint, so Jiang Xia turned to Mist Tengu and asked why it could not grow larger.

After the Mermaid Island murders, Shimabukuro Kimie decided to leave the island, while Jiang Xia returned home with the Mermaid Ghost and learned that Kid was targeting a Blue Sapphire. Kid set out cautiously, wary of Mist Tengu after their previous encounter.

• Jiang Xia learned that Mermaid's skill let someone breathe underwater and added her to the Puppet Clay, gaining a Mermaid appearance.
• The police found a message from Kadowaki Saori on Kuroe Nao's phone, making Saori a major suspect, while Hattori Heiji and Conan suspected she might already be dead.
• Shimabukuro Kimie realized the islanders knew more about the Mermaid and the fire than they admitted, then decided to leave Mermaid Island.
• Shimabukuro Kimie met Hattori Heiji, Conan, Jiang Xia, and the other high school students on the departing ship, and they doubted she had murdered anyone.
• Jiang Xia found news that Kid planned to steal a Blue Sapphire and noted the time and location so he could collect an Energy Core.
• Kid prepared for the theft, remembering Mist Tengu's appearance on the Suzuki Family's ship and setting out cautiously.

Kid traced the Mist Tengu’s past thefts to a supposed man-eating monster, then was rescued from a group of armed men by the Tengu. The Tengu denied eating people and explained that one monk at Shanni Temple had died on his own before being hung up at his request.

• Kid learned that the Mist Tengu had been linked to two monks’ deaths at Shanni Temple and grew wary of being eaten.
• Kid stole a gem carrying a police transmitter, then escaped to the rooftop, where Slack and armed Men in Black confronted him and shot his Hang Glider.
• The Mist Tengu grabbed Kid’s cape and pulled him off the rooftop, then carried him away from the pursuers.
• Kid suspected the Mist Tengu was keeping him alive to make him steal and asked whether it planned to eat him.
• The Mist Tengu said humans were not tasty and claimed the Old Monk had collapsed on his own before asking to be hung up high to attract temple visitors.

Kid learned that the Old Monk had likely murdered his disciple and framed Mist Tengu, which later killed the monk by frightening him and hung him from the eaves. Mist Tengu took Kid’s gemstone, and Kid left realizing the yokai had also rescued him from the Men in Black.

• Kid concluded that the Old Monk had killed Zhongnian and staged the murder to blame Mist Tengu.
• Mist Tengu demanded Kid’s gemstone and threatened to eat a human, so Kid handed it over.
• Mist Tengu crunched the gemstone’s Energy Core while Kid waited, hoping to recover the damaged jewel afterward.
• Kid asked when Mist Tengu would repay him, and Mist Tengu implied it had just saved him from the Men in Black.
• Kid asked why Mist Tengu targeted him instead of museums or jewelry stores, and Mist Tengu insisted it never stole because Kid had stolen the gemstone.

After learning that the Mist Tengu would not eat people as long as it had gemstones, Kid left with Jii and followed the Men in Black to a mountain courtyard. The Mist Tengu attacked the group and abducted Slack, leaving Kid worried that it had lied about its intentions.

• Jiang Xia noticed Inspector Nakamori approaching, returned the drained Blue Sapphire to Kid, and flew off to collect Killing Intent from Slack.
• Kid escaped with Jii Konosuke and used a Locator to track the Men in Black, whom he suspected might know what happened to Kuroba Toichi.
• Jii drove Kid to a wooded courtyard in the mountains, where the Men in Black had stopped.
• The Mist Tengu dropped Smoke Bombs and Anesthetic Darts onto the Men in Black, then seized Slack as he fled the smoke and carried him into the woods.
• Jii tried to leave, but Kid rushed into the woods to check whether the Mist Tengu had truly meant what it said about not eating people.
