The official website for the Detective Conan anime film series announced on Wednesday that the 24th film of the franchise, Meitantei Conan: Hiiro no Dangan (Detective Conan: The Scarlet Bullet) is set for release in Japan on April 16, 2021, and posted trailers with the new release date. The film was originally scheduled to be released on April 17, 2020, but has been postponed for one year due to the impact of the COVID-19 pandemic.
In light of the one year delay, TOHO promoted the new film with a "Reload Project" video which counted "12 rounds" — 12 of the films in the Detective Conan franchise.
The film centres on the FBI agent Shuichi Akai, his younger brother and professional shōgi player Shukichi Haneda, his younger sister and high school detective Masumi Sera, his mother Mary Sera, and Conan Edogawa himself.
The story is set in Tokyo. The world's largest sports festival "WSG: World Sports Games," which only takes place once every four years, is scheduled to be held soon. And it is also announced that the world's first "vacuum superconducting linear" train will start running from Nagoya to Tokyo in conjunction with its opening ceremony. Then, the event's prominent sponsors are kidnapped at a party venue. Shuichi Akai is monitoring the incident and the FBI is waiting for an instruction from him. Meanwhile, Conan finds a connection between the kidnap and the abominable WSG successive abduction happened in Boston 15 years ago, which was also investigated by the FBI. Is this just a coincident? What will happen in Tokyo where people are gathering from all over the world?
Tomoka Nagaoka (Detective Conan: Fist of Blue Sapphire) is directing the film, and Takeharu Sakurai (Detective Conan: Zero the Enforcer) wrote the script. Katsuo Ono returns to compose the music. Rock band Tokyo Jihen is performing the theme song "Eien no Fuzaishōmei" (The Eternal Alibi).
