Having discovered [[Ninzaburo Shiratori|Shiratori]] and [[Hyoue Kuroda|Kuroda]], Conan sneaked after the two to an [[Wikipedia: Interpol|Interpol]] underwater facility known as Pacific Buoy. The facility hosts the new system that allows connection to all surveillance camera in Japan, Europe, and eventually worldwide. Headed by Yosuke Makino, four other engineers (Ed from India, Grace from France, Leonhardt from Germany, and Naomi Argento from United States) also worked in the facility. Also available is the "All-Age Recognition" system, which uses facial recognition and [[Wikipedia: Artificial intelligence|AI]] reconstruction of facial structure to identify individuals whose age may have differed from the source material.

The same night, [[Chianti]], Vodka, and Pinga kidnapped Haibara from Sonoko's resort.

Later on, Vermouth informed Gin that after running the All-Age Recognition system once again, she discovered that the system is able to pick up the image of the person with similar faces, but not necessarily the same person, indicating that the system is flawed. Frustrated by this development and following order from [[Kanenori Wakita|Rum]], Gin decided to use the submarine to destroy the Buoy. However, when he tried to confront Haibara and Naomi, he discovered that the two have escaped from the submarine under the clues provided by Kir.

<spoiler>Conan went back to the Buoy and revealed via Kogoro that the person who murdered Leonhardt is '''Grace'''. Grace murdered Leonhardt as he has examined the access log and discovered that Grace is the only person accessing the camera footage. Grace is then revealed to be '''Pinga''', who used deepfake to fake Leonhardt suicide footage and tried to escape from the Buoy. With the submarine setting to attack the Buoy, Conan tries to light the position of the submarine from underwater and arranged for [[Shuichi Akai|Akai]] to shoot the rocket that severely damages the submarine, forcing the Black Organization to flee from the submarine.

Detective Conan: Black Iron Submarine (名探偵コナン 黒鉄の魚影,Meitantei Konan: Kurogane no Sabumarin?) is the 26th movie in the Detective Conan franchise and the fourth about the Black Organization. It was released in Japan on April 14, 2023 and it was directed by Yuzuru Tachikawa and written by Takeharu Sakurai. The movie grossed 13.88 billion yen, becoming the second highest grossing film in the franchise, surpassing The Bride of Halloween. The movie have its pre-story tie-in episode, The Cameras Targeting Haibara.
The movie was screened at Anime Expo on July 5, 2025 with English subs, and then at Anime NYC on August 23, 2025 with English dub produced by Bang Zoom! Entertainment. Shortly after, the movie was released in North America at digital stores on August 24, 2025. As part of the Detective Conan: Cinema Saturdays event in Anime! on TMS Official Channel channel, the movie had a limited free release between December 27, 2025 to January 7, 2026 with English dub.
The movie revolves around the new Interpol marine facility "Pacific Buoy", where a female engineer is kidnapped by the Black Organization, seeking some information in her USB drive. Meanwhile, Conan is concerned that Haibara's identity might have been exposed during the incident.
In Frankfurt, an Europol agent is being chased by Kir and Gin. Although Kir tries to help her escape, Gin eventually murders the agent. Some time later, Conan, Ran, the Detective Boys, Agasa, and Kogoro are invited to the resort at Hachijo-jima, owned by Sonoko's family. Conan later receives information from Subaru about the Europol agent who was murdered and a new Black Organization agent known as Pinga is on the move.
Kir had attempted to spare Nina Balmer, but Gin shot her by firing a bullet through Kir’s shoulder which struck Nina in the head.
Having discovered Shiratori and Kuroda, Conan secretly went after them to an Interpol underwater facility known as the Pacific Buoy. The facility hosts a new state-of-the-art system that allows them to connect to all the surveillance cameras in Japan, Europe, and eventually all over the world. Headed by Yosuke Makino, four other engineers (Ed from India, Grace from France, Leonhardt from Germany, and Naomi Argento from United States) also work in the facility. Another function of the system is the "All-Age Recognition" system, which uses facial recognition and AI reconstruction of a person’s facial structure to identify individuals whose age may have differed from the source material.
At the same time Bourbon and Vermouth have secretly infiltrated the Pacific Buoy and arranged for the kidnapping of Naomi Argento, holding her captive in a submarine. They along with Vodka and Kir discover from Naomi's flash drive that was hidden in her necklace that the All-Age Recognition system had apparently identified Haibara as Shiho Miyano.
Vermouth and Bourbon secretly kidnapped Naomi from the pacific buoy by knocking her unconscious.
That same night, Chianti, Vodka, and Pinga kidnap Haibara from Sonoko's resort. Conan and Agasa try to chase after them, but unfortunately witness Vodka and Pinga driving their vehicle with Haibara into the sea to board their submarine underwater. The incident was reported to Kuroda, and Conan asked to use the Buoy's surveillance system to check the security cameras on the route of the car chase and the presence of the submarine, but they discovered that no submarine or vehicles were caught on the camera, seemingly indicating that the system had been tampered with.
After discovering that Haibara and Sherry were one in the same, Vodka and Pinga drugged Haibara and kidnapped her.
However, Leonhardt had figured out who the person responsible for tampering with the surveillance footage was and tried to confront the culprit, but was drugged and was seen on the cctv camera committing suicide via poisoning in the Buoy's Cafe. The confession letter apparently written by Leonhardt also mentioned that he was responsible for the Backdoor in the Buoy's system.
Suicide?
Location:Pacific Buoy, Hachijo-jima, Japan
Victim:Leonhardt
Cause of death:Poisoning
Suspects:Grace, Ed, and Yosuke Makino
Conan and the others witnessed Leonhardt apparently committing suicide by taking a poison capsule.
Meanwhile, Vodka tried to force Naomi to tell them how to use the All-Age Recognition program, and when she refused to do so, he arranged for her father, a member of the European Parliament that proposed the use of the surveillance system, to be killed.
Naomi was forced to watch as Korn murdered her father.
Later on, Vermouth informed Gin that after running the All-Age Recognition system once again, she discovered that the system is able to pick up the image of other people with similar faces, but not necessarily the same person, indicating that the system is flawed. Frustrated by this development and following orders from Rum, Gin decided to use the submarine to destroy the Buoy.

Grace murdered Leonhardt as he had examined the access log and discovered that Grace was the only person who accessed the camera footage. Grace is then revealed to be Pinga, who used the Deepfake method to fake Leonhardt’s suicide footage and tried to escape from the Buoy. With the submarine set to attack the Buoy, Conan tries to light the position of the submarine from underwater and arranged for Akai to launch a rocket that severely damaged the submarine, forcing the Black Organization to flee from the submarine. Pinga dies from the blast when the submarine exploded as Gin had intentionally left him there to die. Conan later loses consciousness underwater, only to be rescued by Haibara who went after him and took him to the surface.

During the mid-credits scene, the Detective Boys reunite with Conan and Haibara. Jodie is seen visiting Nina's grave with Hans. It is revealed on the news that Naomi's father had survived the attempted murder by the black organization.
In the post credit scene, the Pacific Buoy project is reported to have been moved to another country. Naomi realizes that Haibara is in fact Shiho Miyano, a friend who shielded her from being bullied when they studied in the United States. Furuya told Conan that the flaw in the system is revealed to have been staged by Vermouth, who disguised herself as Sherry and appeared in security camera footages around Shibuya, Okinawa, and Manila, to hide the fact that Haibara is Shiho Miyano. An elderly woman whom Haibara earlier in the movie had offered her ticket to purchase a Fusae Campbell-branded ginkgo leaf pin is revealed to be Vermouth, who thinks to herself that Silver Bullet should figure out the reason she helped fabricate the flaw in the system himself.
