A Detective Conan compilation film titled Detective Conan: Ai Haibara Monogatari ~Kurotetsu no Mystery Train~ will begin screening in Japanese theaters on January 6, 2023, a few months before the release of the new Detective Conan: Kurogane no Submarine movie. A visual and brief promotional video for the compilation movie have been released.
Kurotetsu no Mystery Train~ will use the series’ The Jet-Black Mystery Train arc as its main base and will have scenes related to Haibara’s past as well. Comic Natalie reports that there will also be new footage at the end that ties into Kurogane no Submarine.
Detective Conan: Kurogane no Submarine is set to premiere on April 14. The story involves an ocean facility called the Pacific Buoy, which serves to connect the security cameras of police around the world and is testing a new technology that makes use of facial recognition. After learning from Subaru Okiya that a Europol member has been assassinated in Germany, Conan sneaks into the Pacific Buoy and discovers that an engineer with an important USB has been kidnapped by the Black Organization. Meanwhile, a dark shadow is creeping up on Ai Haibara.
Yuzuru Tachikawa (Detective Conan: Zero the Enforcer, Mob Psycho 100 Season 3 chief director) is directing the new Detective Conan movie with Takeharu Sakurai (Detective Conan: The Scarlet Bullet) as scriptwriter and Yuugo Kanno (Detective Conan: The Bride of Halloween) as music composer. TMS Entertainment is the animation production company.
The Shogakukan-published Detective Conan manga by Gosho Aoyama, titled in English as Detective Conan by Shogakukan Asia and Case Closed by Viz Media, started serialization in 1994 and has 102 tankoubon volumes as of September 2022. It is serialized in Weekly Shonen Sunday.
Viz Media describes the manga as:
Precocious high school student Jimmy Kudo uses his keen powers of observation and astute intuition to solve mysteries that have left law enforcement officials baffled. Hot on the trail of a suspect, Jimmy is accosted from behind and fed a strange chemical which physically transforms him into a grade schooler! Taking on the pseudonym Conan Edogawa, he attempts to track down the people who did this to him. But until he finds a cure for his bizarre condition, Jimmy continues to help the police solve their toughest cases.
The TV anime adaptation of the manga began airing in 1996 and is still ongoing. There have also been various spin-offs and OVA adaptations. This year’s Detective Conan film, The Bride of Halloween, is the 43rd top-grossing movie in Japan with 9.74 billion yen (~US$70.2 million) and the highest-grossing film in the franchise.
