At the Cocoon presentation, Seiya impressed the wealthy guests with his maturity, prompting them to approach Tomoko Suzuki about marriage matches. The event then turned into a murder investigation when Cocoon developer Kashimura was killed and left the message “JTR.”

• Yusaku Kudo recognized Kashimura's dying message, “JTR,” as a clue meant for him and let Conan work out its meaning.

Seiya and Yusaku Kudo deduced that Kashimura’s dying message read RTJ, pointing to Jack the Ripper and the Old London Cocoon scenario. Conan entered the game to investigate, while Yusaku pursued the real-world killer, and Seiya returned to find Sonoko had joined the players.

• Seiya explained that Kashimura’s weakening pressure on the keyboard showed that the letters should be read as RTJ, and Yusaku Kudo recognized the reference to Jack the Ripper.

• Seiya returned to the launch event and found Sonoko seated inside Cocoon.

• Tomoko Suzuki argued that Seiya and Sonoko were good children, but Noah's Ark refused to stop the trial.
• Ran and Sonoko comforted the frightened children while Seiya compared their situation to Sword Art Online and recognized that the group faced a difficult trial.

Seiya urged the frightened children to choose a game scenario and led a group into Old London to find and defeat Jack the Ripper. Noah's Ark limited the number of participants per scenario, and Seiya entered the game wary that one of the bratty boys might be Hiroki.

• Seiya rebuked the crying children and told them they could only save themselves by clearing a game.
• Conan, Ran, Sonoko, and other children chose the Old London scenario, and many hesitant participants followed Seiya.
• Noah's Ark announced that no more than twelve people could enter each scenario and that clearing any one game would save everyone.

• Seiya and the other eleven participants entered nineteenth-century London and learned they had to find and defeat Jack the Ripper and survive.

Seiya chased Jack the Ripper through the Old London scenario after Conan’s gadgets failed, but Noah’s Ark altered the game and caused a bridge to collapse, letting the killer escape. Outside the game, the adults realized Noah’s Ark was sabotaging the children and turned their attention to finding Kashimura’s murderer.

• Kogoro Mori blamed Noah’s Ark for changing the scenario and cutting off communication, while Yusaku Kudo urged everyone to trust the children and investigate Kashimura’s murder.

After Seiya failed to catch Jack the Ripper, Sonoko scolded him for taking a reckless risk in the game. Haibara reflected on Seiya and Sonoko’s close sibling bond, while Conan learned that their relationship mattered deeply to Seiya.

• Seiya told Conan and the others that the stone bridge collapsed just as he was about to catch Jack the Ripper, while suspecting Hiroki had caused it to keep the game’s clues intact.
• Sonoko struck Seiya and ordered him not to chase danger alone, and Seiya apologized after she threatened to make him listen to her.

After Jack the Ripper escaped and harmed more women, Conan proposed seeking Sherlock Holmes’s help to uncover the killer’s identity. On the way to Baker Street, Sonoko suspected a strange singing homeless man was Jack the Ripper, but Conan challenged her reasoning, leaving her demanding that Seiya explain her deduction.

• Conan suggested gathering evidence and consulting Sherlock Holmes because Jack the Ripper was too skilled to catch without clues, and Seiya agreed with the plan.
• Hideki Morohoshi drew the group’s attention to a clock tower whose hands moved backward, and Conan deduced that it counted players eliminated from Cocoon’s other scenarios.
• As the group headed for 221 Baker Street, they heard that Jack the Ripper had struck again and encountered a homeless man singing a warning about him.
• Sonoko declared that the homeless man was Jack the Ripper because he seemed creepy and had appeared nearby after the crime.
• Conan questioned why Jack the Ripper would draw attention to himself by singing, and Sonoko insisted her deduction was right and asked Seiya to explain it.

Seiya and Conan’s group failed to find Sherlock Holmes, and Seiya suspected the hand-organ-playing vagrant was an important NPC. Outside the game, Yusaku Kudo realized Noah’s Ark had changed the scenario, while his pointed remark made Chairman Sindora fear he had been identified as Kashimura’s murderer.

• Seiya argued that the vagrant’s warning song marked him as a crucial NPC, and Conan and Little Ai understood his theory.
• Seiya’s group reached 221B Baker Street and learned that Holmes and Watson had left London.
• Yusaku Kudo and the others realized Noah’s Ark had changed the plot, removed Holmes’s help, and made the game much harder.
• Kogoro Mori grew furious at Noah’s Ark, while Yusaku trusted the children to uncover the truth and hinted at a culprit outside the game.
• Inspector Megure asked whether Yusaku had identified Kashimura’s murderer, and Chairman Sindora angrily demanded evidence after Yusaku addressed him.

Yusaku Kudo identified Chairman Sindora as Kashimura’s murderer, and Seiya’s actions helped uncover evidence Sindora had tried to destroy. Sindora was left unable to explain away the matching fingerprints on the fake dagger.

• Yusaku Kudo explained that Sindora had swapped the sculpture’s dagger for an aluminum foil copy during the blackout and used the original to kill Kashimura.
• Yusaku showed footage of Seiya touching the dagger, and Inspector Megure reasoned that Seiya’s fingerprints should be on it if it was the original.
• Sindora claimed he had covered Seiya’s fingerprints, but Officer Chiba arrived with a half-burned foil dagger bearing both Seiya’s and Sindora’s fingerprints.
• Seiya recalled that he had touched the sculpture’s dagger to replace Hideki Morohoshi’s role in leaving fingerprints, then found Sindora trying to burn the foil dagger and gave it to Tomoko Suzuki.

Sindora was placed under house arrest while Inspector Megure sought an arrest warrant, but he found Cocoon’s prototype and saw a chance to enter the game. In Old London, Seiya and Conan traced Jack the Ripper’s connection to Professor Moriarty and headed for Colonel Moran’s Poker Club, where the children’s reckless infiltration plans left Conan exasperated.

• Inspector Megure ordered Shiratori and Chiba to confine Sindora while he applied for a formal arrest warrant.
• Sindora recognized Katamura’s Cocoon prototype and recalled that its test unit could enter a game scenario as a character.
• Seiya’s group found clues at Sherlock Holmes’s home linking Jack the Ripper to Professor Moriarty and learned they needed to find Colonel Moran.
• Hideki Morohoshi took Holmes’s revolver and urged the other rich children to rely on themselves rather than Seiya and Conan.
• At the Poker Club, the children insisted on joining the dangerous infiltration, while Seiya chose to stay outside with Sonoko and Conan regretted losing his planned team.

Conan led Ran and the children into the Poker Club to confront Colonel Moran, but Hideki Morohoshi provoked a gunfight that got most of the group eliminated. Outside the game, the wealthy parents pinned their hopes on Seiya Suzuki, whose survival could save everyone.

• Sonoko worried about Ran and the children, while Seiya warned that their group was burdened with too many disadvantages.
• Conan and the others found Colonel Moran cheating at cards, but Hideki Morohoshi and the other rich heirs confronted him with a stolen revolver.
• Moran recognized Sherlock Holmes's initials on the revolver and ordered his men to kill the children, triggering a brawl and gunfight.
• Ran fought to protect the group, but the rich heirs and Teitan's Three Fools were eliminated one after another.
• The eliminated children's parents blamed Hideki Morohoshi and then asked Mrs. Suzuki to rely on Seiya to save their children.

Conan tried to use Professor Moriarty’s wine to bargain with Colonel Moran, but Moran held Ran at gunpoint and demanded the wine. Seiya arrived with the real Professor Moriarty as a hostage, shifting the balance in the Poker Club.

• Conan took a bottle of wine meant for Professor Moriarty and threatened to smash it to make Colonel Moran back down.
• Colonel Moran knocked Ran down, held a gun to her head, and demanded Conan hand over the wine in exchange for her life.
• Conan hesitated over the bargain, worried that Moran’s gang would still kill the others after Ran was released.
• Seiya entered the Poker Club carrying Professor Moriarty as a hostage and threatened to use him as leverage.
