Detective Conan: Black Iron Submarine
TMS Entertainment
Released in Japan on April 14, 2023, Black Iron Submarine is the 26th Detective Conan film and the fourth built around the Black Organization's conspiracy. When the Black Organization kidnaps Ai Haibara, Conan is forced onto a mysterious submarine to rescue her while uncovering more of the organization's secrets in the confined, claustrophobic setting. The plot converges with a separate storyline at Interpol's 'Pacific Buoy' marine facility on Hachijo-jima, where engineers from around the world are gathered to launch a new global facial-recognition law-enforcement system — a target too valuable for the Black Organization to ignore. Directed by Yuzuru Tachikawa (Mob Psycho 100, Death Parade) and written by longtime Conan screenwriter Takeharu Sakurai, the film grossed 13.88 billion yen, making it the second-highest-grossing film in franchise history at the time of release.

Who directed Detective Conan: Black Iron Submarine?
Yuzuru Tachikawa, known for directing Mob Psycho 100 and Death Parade, directed the film from a screenplay by longtime Conan franchise writer Takeharu Sakurai.
