• Grandma Senma looked down from the helicopter window, saw something below, and pressed herself against the glass in shock.

Amuro Tooru brought down part of Twilight Mansion’s outer wall to expose the gold hidden inside and draw witnesses, while keeping his Bourbon identity secret. Jiang Xia guessed his boss’s plan and postponed revealing himself as Uzo, and the Detectives debated why the Golden Mansion looked unfinished.

• Amuro Tooru exposed the gold inside Twilight Mansion’s walls and chose to preserve his Bourbon cover while leaving the gold’s fate to the police and the Organization.

• Kurosawa asked whether the Golden Mansion or the Cowboy Detective’s Alfa Romeo was more beautiful, making the Cowboy Detective crush his cigarette and turn away.

Ikumi Soda, Saguru Hakuba, and Kid staged fake deaths with tomato sauce while Amuro Tooru investigated the apparent murders. At the Central Control Room, the Cowboy Detective discovered a poison-needle trap on the door, just as the staged deaths left Amuro surrounded by apparent victims.

• Ikumi Soda went to the Central Control Room, intending to fake her death using its poison-killing device instead of entering the treasure's location.
• Amuro Tooru and Kid found Saguru Hakuba lying in a pool of tomato sauce, and Amuro pretended to confirm that Hakuba had been shot through the heart.

• Kid planned to have Jiang Xia identify Amuro Tooru, but could not locate him or confirm that Jii had found him.

• The detectives and police escorted Amuro to the police station for questioning while keeping him under watch.
• Amuro told the police that Jiang Xia might have been replaced near the Gas Station and secretly instructed Kazami Yuuya to detain Matsuda and investigate him.

After being found at a gas station, Jiang Xia left with Amuro Tooru once the police finished questioning them. Amuro then learned that the Organization’s Boss already knew about Twilight Mansion and began suspecting Kurosawa or someone else among the Detectives and police had reported the discovery.

• Amuro Tooru and the police found Jiang Xia at a gas station, where he was eating oden after the staff discovered him in a warehouse.
• Kid, disguised as a staff member, confirmed that Jiang Xia was safe and quietly left, pleased that the police had detained the suspected kidnapper.

• Jiang Xia picked up the Dice and looked at Amuro Tooru in confusion.

• Hattori Heiji told Toyama Kazuha that Amuro Tooru might be holding a hostage to keep Jiang Xia from alerting the police.

Jiang Xia, Hattori Heiji, Amuro Tooru, and Toyama Kazuha visited a college festival haunted house and were asked to critique Yumi Anzai’s corpse acting for a student horror film. The students prepared to guide them through the haunted house’s branching paths, while several staff members joined in the performance.

• Yumi Anzai recognized Jiang Xia as a Tokyo High School Detective and identified Hattori Heiji as the Osaka High School Detective, teasing him about his blurry newspaper photos.
• Yumi Anzai invited the detectives to judge her corpse acting for a horror film, and Katori Mutsumi explained that their student group was making it as a graduation project.

Hattori Heiji and Toyama Kazuha used a staged blackout to get Jiang Xia away from Amuro Tooru, believing they were rescuing him from a kidnapper. Jiang Xia remained confused about their plan, and Hattori Heiji realized he might have misunderstood the situation.

• Tsuji Eitaka left the group to search for his missing companion, reducing the haunted house tour group to Amuro Tooru and the three high school students.
• Hattori Heiji and Toyama Kazuha warned Jiang Xia not to move, then fled with him when the haunted house lost power and unfamiliar burly men rushed in.
