Detective Conan: The Raven Chaser (名探偵コナン　漆黒の追跡者(チェイサー), Meitantei Konan: Shikkoku no Cheisā) is the thirteenth film installment of the Case Closed manga and anime series. The film was released in Japan on April 18, 2009. This film earned 3.9 billion yen in the domestic Japanese box office, making it the highest-grossing film in the Case Closed series so far. The film involves active members of the Black Organization, making this the Black Organization's second appearance in a film since Countdown to Heaven. A special preview to the film aired in Japan on Animax. A new member from the Black Organization that shrunk Shinichi's body manages to find out about Shinichi's transformation into Conan. This discovery starts to put those around him in danger as Gin and the other Black Organization members start to take action. The film was nominated for Best Animated Film at the 2010 Awards of the Japanese Academy.

A man driving down a hillside road suddenly realizes that his car's brakes don't work. Traveling at a high speed, the Alfa romeo Brera crashes into a toll station. The man dies but leaves a mysterious dying message: "Tanabata kyo." A mysterious Mahjong tile next to the body links this case to six other homicide cases in Tokyo, Kanagawa, Shizuoka, Nagano, and other places in Japan. Because of the Mahjong tiles left beside each victim, the police conclude that the same person or organization committed these large-scale murders. The police of prefectures across Japan unite to find the murderer.

After a police conference about this case, Conan discovers a police officer walking out of the building and entering a black Porsche. He concludes that a Black Organization member is disguised as a police officer and has infiltrated the meeting. Conan is left wondering which officer is the fake and what interest the Black Organization has in the case.

On the day of Tanabata, Conan corners Vermouth in the underground parking lot of a shopping mall and interrogates her. She says that the Black Organization needs a memory chip and has a new member, "Irish".

Conan employs the help of Heiji Hattori and tries to solve the serial murder case by following the dying message lead. He and Heiji find out that two years ago, there was a fire accident in a hotel in Kyoto, and a young woman named Nanako Honjou died. The elevator could only hold seven, but eight people needed to escape. Nanako wasn't on the last elevator and couldn't escape. Conan tracks down her neighbor, Shun Sawamura, and asks him some questions.

Conan finds out that Nanako and her boyfriend, Kosuke Mizutani, often went star gazing together. Conan realizes that the crime scenes form the Big Dipper constellation along with the North Star Polaris.

When the police arrive at a deserted Tokyo Tower, Conan sneaks past them and confronts Mizutani, who confesses to the crimes and intends to commit suicide by poison.

Mizutani thought one of the seven must have pushed Nanako out of the elevator during the hotel fire, but Nanako's brother, Kazuki Honjou, who was one of the seven in the elevator, shows up and testifies that she voluntarily stepped out. Conan reveals that the real murderer is Kazuki Honjou and not Mizutani because Mizutani would never commit murder to stain the memory of Nanako and his precious stars. However, Kazuki, obsessively fond of his younger sister, decided after her death to take revenge on all those who "took her away from him", including Mizutani. To this purpose, Kazuki tricked Mizutani to become a scapegoat by persuading him to take the blame for the revenge murders. The mahjong stones left at the murder scenes were deliberate clues to point the police investigation into Mizutani's direction, with the final stone pinpointing the location of Tokyo Tower - a fact which both Conan and Kogoro have managed to deduce.
