**Detective Conan: The Crimson Love Letter** (名探偵コナン から紅(れない)の恋歌(ラブレター) ,*Meitantei Konan: Karakurenai no Raburetā*[?](/wiki/Help:Japanese "Help:Japanese")) is the 21st [movie](/wiki/Regular_movies "Regular movies") of the *[Detective Conan](/wiki/Detective_Conan "Detective Conan")* franchise. It was released in Japan during Golden Week on April 15th, 2017 and it was directed by [Kobun Shizuno](/wiki/Kobun_Shizuno "Kobun Shizuno") and written by [Takahiro Okura](/wiki/Takahiro_Okura "Takahiro Okura"), it was released following [movie 20](/wiki/The_Darkest_Nightmare "The Darkest Nightmare"). The movie earned over 6.89 billion yen. The movie would have its pre-story tie-in episode, [The Mystery of the Vanished Black Belt](/wiki/The_Mystery_of_the_Vanished_Black_Belt "The Mystery of the Vanished Black Belt").
The movie was screened with English dub produced by [Bang Zoom! Entertainment](http://en.wikipedia.org/wiki/Bang_Zoom!_Entertainment "wikipedia:Bang Zoom! Entertainment") on Chara Expo 2019, and then released at digital stores in [North America](/wiki/Case_Closed "Case Closed") on November 19, 2020. [Discotek Media](http://en.wikipedia.org/wiki/Discotek_Media "wikipedia:Discotek Media") released the movie on home video on December 29, 2020. As part of the *Detective Conan: Cinema Saturdays* event in [Anime! on TMS Official Channel](https://www.youtube.com/@AnimeonTMSOfficialChannel) channel, the movie had a limited release between October 4 to October 15, 2025 with English dub.
It is the second movie focused on [Heiji Hattori and Kazuha Toyama](/wiki/Heiji_Hattori_and_Kazuha_Toyama "Heiji Hattori and Kazuha Toyama"), particularly on Kazuha. Its main theme is the Japanese card game of [karuta](http://en.wikipedia.org/wiki/Uta-garuta "wikipedia:Uta-garuta"). It is also the introduction of [Momiji Ooka](/wiki/Momiji_Ooka "Momiji Ooka"), a karuta champion from Kyoto and Heiji's self-declared future wife, and her butler [Muga Iori](/wiki/Muga_Iori "Muga Iori"). In Kyoto, the incubent karuta champion of the high-school Satsuki Cup [Toshiya Yajima](/wiki/Toshiya_Yajima "Toshiya Yajima") is killed in his mansion by a black figure. Later that day, [Conan](/wiki/Conan_Edogawa "Conan Edogawa"), [Ran](/wiki/Ran_Mouri "Ran Mouri"), [Kogoro](/wiki/Kogoro_Mouri "Kogoro Mouri"), the [Detective Boys](/wiki/Detective_Boys "Detective Boys"), Heiji, and Kazuha attend the filming of a karuta TV program in Osaka along with Kazuha's friend [Mikiko Hiramoto](/wiki/Mikiko_Hiramoto "Mikiko Hiramoto"). They meet the organizer of the Satsuki Cup [Kensuke Achiwa](/wiki/Kensuke_Achiwa "Kensuke Achiwa"). However, they are the target of a vicious bombing, which they narrowly survive. In these two crimes, the culprit left a mysterious karuta card, hinting to further crimes. At the same time, Satsuki Cup finalist [Koji Sekine](/wiki/Koji_Sekine "Koji Sekine") is seen in front of Yajima's body. Moreover, [Togo Kaieda](/wiki/Togo_Kaieda "Togo Kaieda"), Achiwa's secretary is moving in the shadows. Heiji and Conan are ready to solve the crime, but it takes more than brains to go against a very calculating serial killer.
