# Case Closed: The Crimson Love Letter

Case Closed: The Crimson Love Letter, known as Detective Conan: The Crimson Love Letter (名探偵コナン から紅(くれない)の恋歌(ラブレター), Meitantei Konan: Kara Kurenai no Rabu Rettā) in Japan, is a 2017 Japanese animated film directed by Kobun Shizuno and written by Takahiro Okura. It is the twenty-first installment of the Case Closed film series based on the manga series of the same name by Gosho Aoyama, following the 2016 film Case Closed: The Darkest Nightmare. The film was released in Japan on April 15, 2017.

## Plot

A bombing case at Nichiuri TV in autumn. The Satsuki Cup, which crowns the winner of Japan's Ogura Hyakunin Isshu based competitive karuta tournament, is currently being filmed inside the facility. The incident results in a big commotion and, while the building is burning to ashes, the only people left inside are Heiji and Kazuha. They get rescued just in time by Conan, who rushes to the scene. Both the identity and motive of the bomber are unknown.
While confusion takes over due to the explosion, Conan meets a mysterious beautiful girl who claims she is "Heiji's fiancée". Her name is Momiji Ooka and she is the Kyoto High School karuta champion. As fate would have it, Kazuha is going to face Momiji in the Hyakunin Isshu competition, so she begins to train with the help of Heiji's mother, Shizuka, who is a skilled karuta player.
At the same time, in a Japanese house in Arashiyama, Kyoto's outskirts, the reigning Satsuki Cup champion is murdered. Pictures of the crime scene reveal Momji's presence. Additionally, several karuta cards were spread around the victim.
Conan and Heiji, along with the Osaka and Kyoto police departments, begin their investigation on the Satsuki Cup and the related murder case. As the inquiry goes on, they come across a secret connected with the Hyakunin Isshu.
After the case is solved, Momiji tells Heiji that he promised to marry her when they were little. Heiji suddenly remembers that this wasn't the case: when they were little, he said he'll be even stronger (tsuyome), but she misheard it as "yome" (bride).

## Production

Aoyama cited the live-action adaptations of Yuki Suetsugu's manga series Chihayafuru among his inspirations for making Hyakunin Isshu and karuta subjects of a Case Closed film. He noted the Kyoto-based Karuta Queen, or national champion in the women's division, as depicted in Chihayafuru, as the model for characters in The Crimson Love Letter. The visual poster for this film was unveiled on January 17, 2017.

## Reception

In January 2018, The Crimson Love Letter was nominated for the Japan Academy Film Prize of "Excellent Animation of the Year." Rebecca Silverman of Anime News Network reviewed the film in 2020. While finding criticism in the romantic subplot being weak and the overarching mystery requiring some karuta knowledge to solve it, she praised the "beautiful use of color and animation" and the comradery between Conan and Heiji, concluding that: "The Crimson Love Letter is an all-around enjoyable film. The mystery is interesting and fair play, the characters' interactions are fun, and the whole thing is very nice to look at."
