Chapter Summaries

Kid, disguised as Jiang Xia, tried to keep his cover while the detectives gathered at Twilight Mansion. Saguru Hakuba arrived with his hawk, which attacked Jiang Xia’s Ghost Mist Tengu before someone grabbed its wing.

• Kid stayed quiet after Ikumi Soda greeted him and worried that a murder could expose his disguise if he could not solve the case quickly.
• Saguru Hakuba came downstairs and explained that Twilight Mansion was associated with an unsolved massacre from forty years earlier.
• Amuro Tooru watched Jiang Xia suspiciously, wondering if he was thinking of picking a fight with Hakuba.
• Hakuba whistled for his hawk, but it flew toward Jiang Xia and its talons passed through Mist Tengu.
• Mist Tengu panicked and fled into Jiang Xia’s arms, and an unidentified person seized the hawk’s wing as it approached again.

Kid traded Mist Tengu his accumulated magic power for the sedated Jiang Xia, then noticed the Detective had no phone and reconsidered the suspicious events surrounding his capture. He decided to have Jii watch Jiang Xia and later take him to the Police Station, believing Jiang Xia might be in danger from Amuro Tooru.

• Mist Tengu drained Kid's magic power and handed over the sedated Jiang Xia, whose breathing and condition Kid checked.
• Kid asked Mist Tengu whether the witches had returned to trouble him, and Mist Tengu said he had been busy looking for them.
• Kid discovered Jiang Xia had no phone and recalled how calmly he had evaded the Stun Gun and fled toward the Deep Forest.
• Kid suspected Jiang Xia might have been caught up in a kidnapping case and decided to have Jii watch him before taking him to the Police Station.
• Kid concluded Jiang Xia probably had not realized that Mist Tengu had ambushed him, and would likely blame Amuro Tooru for the attack.

Jiang Xia and the other guests settled into the Villa, while Saguru Hakuba grew suspicious of Jiang Xia after his hawk attacked him. When Kid slipped away from the sitting room, Jiang Xia sent Shikigami and a Mist Tengu puppet to follow him, leaving Matsuda Jinpei to operate his puppet.

• Amuro Tooru caught Watson after the hawk attacked Jiang Xia, and Saguru Hakuba took the bird back.
• Grandma Senma mistook Jiang Xia's movement for a heart problem, but he said he was fine and kept the Mist Tengu clinging to his hand.
• Saguru Hakuba offered Jiang Xia heart medicine, then suspected Watson had sensed blood or noticed that Jiang Xia was actually Kid in disguise.
• The maid guided the guests to their rooms and then to the sitting room, where Kid played foosball before secretly leaving.
• Jiang Xia sent Shikigami and a Mist Tengu puppet after Kid, while Matsuda Jinpei took over operating Jiang Xia's puppet.

Matsuda Jinpei used a physical body disguised as Kurosawa Sa while Amuro Tooru tried to determine who he was. Amuro grew increasingly suspicious of his resemblance to Matsuda and discovered that he could answer only with gestures, leaving the reason he could not speak unexplained.

• Matsuda Jinpei adjusted to having a physical body and accepted Amuro Tooru's invitation to play billiards.
• Matsuda Jinpei silently played billiards, while Amuro Tooru wondered whether Kurosawa Sa was the man he had seen in the mountains and how he could have survived the explosion and landslide.
• Amuro Tooru recalled Senma Furuyo's concern about Matsuda's heart and considered whether Kurosawa Sa might be an injured Matsuda Jinpei, then dismissed the idea as impossible.
• As they played, Amuro Tooru noticed Kurosawa Sa looked increasingly like Matsuda Jinpei and tested whether he would respond to questions.
• Amuro Tooru discovered that Matsuda Jinpei could nod or shake his head but would not answer questions aloud.

Amuro Tooru grew increasingly suspicious that Kurosawa was Matsuda Jinpei, but decided to investigate Grandma Senma rather than risk exposing his undercover identity. On the terrace, Kid discovered the bridge had been destroyed and began planning an escape, then eyed the Mist Tengu’s wings as a possible way out.

• Amuro Tooru considered whether Kurosawa was Matsuda Jinpei, but held back from calling him by name because doing so could expose his identity.
• Amuro Tooru decided to begin investigating Grandma Senma, who seemed familiar with Matsuda.
• Kid saw that the bridge leading to Twilight Mansion had been blown up and worried that rescuers might arrive and arrest him.
• Kid considered how to escape before the police arrived, then noticed the Mist Tengu’s folded wings and saw a possible solution.
• Jiang Xia watched the firelight on the bridge as Kid walked closer to him.

Jiang Xia offered Kid the chance to become a winged monster, but Kid declined after weighing the costs. Back in the Villa, Jiang Xia joined the Detectives as they examined bloodstained playing cards before the maid summoned them to dinner.

• Kid hinted that he might need help escaping, and Jiang Xia agreed to take him out if necessary.
• Jiang Xia teased Kid by offering to turn him into a monster with wings, but Kid ultimately refused because of the risks and the burden of supporting another monster.
• Kid warned Jiang Xia that the Villa's Detectives might have guns and urged him to be careful before leaving.
• Jiang Xia returned his consciousness to the puppet occupied by Matsuda Jinpei and found him playing billiards against Amuro Tooru.
• Ikumi Soda found two playing cards stuck together with a dark stain between them, and the Detectives gathered to inspect them.
• The maid announced that dinner was ready and that the master was waiting in the dining room.

Jiang Xia and the other detectives were trapped at Twilight Mansion by an Organizer impersonating Phantom Thief Kid, who demanded they find a hidden treasure. After the Organizer revealed himself to be a remote-speaking model, the detectives began assessing the bizarre challenge.

• Grandma Senma led the guests to the dining room, where they met the hooded Organizer and Kid joined them.
• The Organizer announced that he wanted the detectives to find the villa’s treasure, then explosions destroyed the parked cars and he revealed that the bridge had collapsed and there was no phone signal.
• Jiang Xia questioned the Organizer’s threat, while Amuro Tooru wondered about Kurosawa’s unusual behavior and tried to contact Kazami Yuuya without signal.
• Cowboy Detective pulled off the Organizer’s hood and discovered a plastic model with a speaker in its head.
• Saguru Hakuba remarked that Kid would set riddles rather than ask detectives to solve one, and his chained hawk flew toward Jiang Xia before being yanked back.

The detectives ate at the Villa’s Evening Banquet while speculating about the secretive organizer and the suspicious meal. The organizer revealed that the crest on their tableware belonged to the Karasuma Family and invoked the name of the long-dead Karasuma Renya.

• Saguru Hakuba restrained Watson after the hawk lunged toward Jiang Xia, then wondered what had made it act strangely.
• The detectives concluded that someone had likely impersonated Kid to send the invitations and gather them at the Villa.
• The maid served dinner, and Jiang Xia pretended to handle his soup while the others wiped their tableware and ate.
• After everyone finished the meal without incident, the organizer told them to inspect the tableware beside them.
• Jiang Xia recognized the crow crest as the Karasuma Family emblem, and the organizer identified it as the crest of Karasuma Renya.

The Organizer recounted how two travelers had driven guests into a murderous frenzy at Karasuma Renya’s secret auction forty years earlier, then vanished with valuable art. He challenged the Detectives to find the treasure and hinted that another massacre might unfold in the Villa that night.

• The Organizer described how two travelers gave the auction guests strange cigarettes that filled the Villa with Smoke and triggered hallucinations and violent behavior.
• The guests fought over the Works of Art, leaving eight dead and more than a dozen unconscious, while the travelers escaped with many treasures.
• Amuro Tooru and Kid disguised as Jiang Xia each suspected Jiang Xia’s cigarettes might be connected to the strange substance, while the Real Jiang Xia watched their reactions.
• The maid served tea as the Organizer invited the Detectives to reenact the massacre, claiming only one guest would leave the Castle that night.
• The Organizer gave a cryptic hint about two travelers, a devil, a king, a queen, and a soldier, and Jiang Xia considered whether staged violence might produce Killing Intent.

At a detectives’ gathering, the organizer’s prerecorded announcement was interrupted by the Gourmet Detective’s sudden death from apparent poisoning. The detectives realized the murderer was likely among them and prepared to check whether they could escape the mountain lodge.

• Jiang Xia hoped Saguru Hakuba would display convincing killing intent, and the Mermaid startled Hakuba’s hawk by growing large and patting its head.
• The detectives rejected the organizer’s proposed survival game, while the Cowboy Detective argued they could walk out despite the destroyed bridge and road.
• The Gourmet Detective collapsed and died near Jiang Xia, and the detectives found a bitter almond scent and ruled out his tea with a coin test.
• Jiang Xia removed the plastic organizer’s head and found a timer device and cassette tape, revealing that the announcement had been prerecorded.
• Saguru Hakuba concluded that the murderer was probably among the group, and the Cowboy Detective suggested they inspect the grounds and try to find a way out.

The Detectives discovered that every car in the front parking lot had burned, and the Cowboy Detective mourned his destroyed Alfa Romeo without showing the Killing Intent Jiang Xia hoped to see. After noticing an extra vehicle among the wrecks, the group headed back inside to check the back door, where they nearly ran into Kid disguised as Jiang Xia.

• Amuro Tooru told Kid, disguised as Jiang Xia, to stay in the hall because damaged cars and explosions could trigger Jiang Xia's PTSD.
• The Detectives went outside and found every car in the front parking lot engulfed in flames.
• Jiang Xia watched the Cowboy Detective grieve over his destroyed car, but the Cowboy Detective showed no Killing Intent.
• The Detectives counted five burning cars and identified one as the maid's car, which she had parked by the back door.
• The Detectives went back inside to check whether the maid's car had survived, and Kid narrowly avoided colliding with them at the door.

The detectives found an intact car behind the Villa and chose four people to drive toward the Suspension Bridge, while the others stayed behind to search Twilight Mansion. Saguru Hakuba sent his hawk flying with a note as the search began.

• The group found a Small Yellow Beetle Car outside the Villa’s back door and suspected it might be trapped.
• Kid proposed a coin toss to choose who would ride, and Kid, Amuro Tooru, Grandma Senma, and Jiang Xia got heads.
• Grandma Senma drove the four of them away from the Villa toward the Suspension Bridge.
• After the car disappeared, the remaining detectives returned to Twilight Mansion and split up to search.
• Saguru Hakuba attached a note to his hawk and sent it flying.

Jiang Xia, Amuro Tooru, and Kid investigated the destroyed suspension bridge, where Grandma Senma’s car exploded and plunged into the ravine. After the group returned toward Twilight Mansion, Senma Furuyo emerged from hiding, and her history revealed that she had organized the gathering to avenge the scholars murdered by Karasuma Renya.

• Jiang Xia, Amuro Tooru, and Kid inspected the broken bridge while Grandma Senma stayed in the car.
• The car exploded after Grandma Senma switched to low beams, then rolled down the slope and fell into the ravine.
• Kid, disguised as Jiang Xia, pretended to grieve for Grandma Senma, while Amuro Tooru and Kid recognized her likely role as the organizer.
• Jiang Xia suggested returning to Twilight Mansion, and the three headed back together.
• Senma Furuyo emerged from hiding after they left and began walking toward Twilight Mansion.
• Senma Furuyo’s past revealed that Karasuma Renya had murdered her father and other scholars while they searched Twilight Mansion for treasure, and she had uncovered the truth decades later.

The Gourmet Detective and Senma Furuyo’s schemes were revealed: Senma poisoned the teacups to kill the Gourmet Detective, while planning to fake her own death and watch the detectives search for the Villa’s treasure. After Jiang Xia and the others returned, the detectives gathered outside and confirmed their suspicions about Senma.

• The Gourmet Detective lured detectives to the Villa with a fake Kid invitation and planned to kill them while searching for treasure.
• Senma Furuyo anticipated the Gourmet Detective’s plan and poisoned the teacup handles, causing him to poison himself by biting his thumb.
• Senma planned to fake her death in a car explosion, hide in a locked room, and observe the detectives through surveillance cameras.
• Jiang Xia returned to the Villa with the others and told the gathered detectives that Senma had died in the car explosion.
• The detectives went outside, away from the cameras, and agreed that Senma was the mastermind after Saguru Hakuba recalled her choosing the rusty ten-yen coin.

The Detectives uncovered Senma Furuyo’s plan to poison and arm the guests so they would kill one another, but they still needed to learn how to escape Deep Forest Island. Uzo returned and offered to stage a mutual-slaughter performance to persuade Senma to reveal the way out.

• The Cowboy Detective explained that Senma had contaminated the teacups with Potassium Cyanide and hidden weapons and a poison-needle trap around the Villa.
• Uzo appeared on the second-floor balcony and proposed pretending to carry out Senma’s mutual-slaughter plan so he could ask her how to escape.
• Uzo told the Detectives that he had only met Senma when he sought a ride after his car broke down, and that she had mistaken him for a terminally ill traveler planning to kill himself.
• Amuro Tooru questioned Uzo about the suicide story, and Uzo explained that he had invented it to seem less threatening when asking Senma for a ride.

Jiang Xia persuaded the detectives to stage a convincing massacre so Grandma Senma would reveal how to escape, and warned them their murderous intent had to look real. Grandma Senma returned to Twilight Mansion and watched the detectives argue from her hidden surveillance room.

• The detectives reconsidered whether Kurosawa was Grandma Senma’s accomplice, while Amuro Tooru suspected Matsuda’s terminal illness might be genuine.
• Jiang Xia dismissed the illness theory and asked the detectives to plan how they would appear to die in a staged massacre.
• The detectives agreed to perform the plan, and Kurosawa warned them that Grandma Senma would see through ordinary acting unless they truly wanted to kill one another.
• Grandma Senma returned to Twilight Mansion, entered the hidden surveillance room, and watched the detectives argue in the hall.

Kurosawa persuaded the detectives to split into teams to search the Villa, then searched with Amuro Tooru and Kid. In a piano room, they found an old copy of the treasure clue, and Kurosawa noticed signs that someone had recently sprayed the piano lid.

• Kurosawa suggested locking the Villa and searching in separate teams, and the detectives agreed.
• Jiang Xia, Amuro Tooru, and Kid searched together and found a piano room.
• Jiang Xia discovered an old sheet bearing the same treasure clue given at the Evening Banquet.
• Amuro Tooru concluded that the clue had been left there long ago and that the organizer had passed it on unchanged.
• Kurosawa spotted a damp, unmolded stain on the piano lid and inferred that someone had recently sprayed it.

Amuro Tooru and Jiang Xia examined the piano lid and found fluorescent writing revealed by luminol. The message linked Kyosuke Senma to the treasure, leaving the group with a new clue as the killer remained at large.

• Amuro Tooru wondered whether Kurosawa was secretly Matsuda or an impostor, but decided not to test the disguise while cameras were watching.
• Jiang Xia dismissed Amuro's suspicions and considered how his Uzo identity could make others invent explanations for his quick deductions.
• Amuro Tooru recognized the damp stains on the piano lid as likely traces of Ikumi Soda's luminol and suggested turning off the lights.
• Kid, disguised as Jiang Xia, switched off the lights and joined the others in examining the piano.
• Fluorescent writing appeared on the piano lid: "I have finally grasped the ace that will lead me to the treasure—Kyosuke Senma."

Jiang Xia pretended to be too ill to keep investigating while Amuro Tooru and Kid continued searching the Villa. Elsewhere, Ikumi Soda knocked out the maid, but Saguru Hakuba confronted her and was shot when she fired first.

• Jiang Xia and the other detectives read Kyosuke Senma’s bloody message and considered its connection to Grandma Senma.
• Jiang Xia pretended to collapse and asked Amuro Tooru to take him to a nearby bedroom, where he could wait apart from the investigation.
• Amuro Tooru left Jiang Xia in the bedroom and resumed searching the corridor with Kid, who was disguised as Jiang Xia.
• Ikumi Soda Sneak Attacked the maid, dragged her into a tool room, and hid her there.
• Saguru Hakuba confronted Ikumi Soda with a gun and accused her of being the culprit, but she shot him with a Palm Thunder and headed toward the Central Control Room.

Ikumi Soda, Saguru Hakuba, and a disguised Kid staged deaths as part of Matsuda's plan, while Amuro Tooru played along and searched for clues. In the Central Control Room, the Cowboy Detective discovered a poison-needle trap on the door handle.

• Ikumi Soda headed to the Central Control Room, planning to fake her death using the poison-killing device there.
• Amuro Tooru and Kid found Saguru Hakuba pretending to be dead with tomato sauce on his chest, and Amuro helped make the staged murder look convincing.
• Kid ran toward footsteps, and Amuro found a disguised Kid posing as Jiang Xia at the bottom of the stairs; Amuro suspected the real Jiang Xia was safe and continued the act.
• Amuro followed the apparent killer upstairs and found Ikumi Soda lying in the Central Control Room.
• The Cowboy Detective examined the door handle and revealed that opening it after entering the treasure answer would trigger a poison needle.
