A series of murders occurs across
Tokyo,
Osaka, and
Kyoto, in which five men are killed using traditional Japanese weapons such as sword and bow and arrow. The perpetrator is described as wearing a
Noh mask depicting an elderly man. Investigations conducted jointly by the
Tokyo Metropolitan Police Department, Osaka Prefectural Police, and Kyoto Prefectural Police reveal that the victims were all members of Genji Hotaru, a criminal group specializing in the theft of antique art. The remaining known members of the group are its leader, known as Yoshitsune, his subordinate Benkei, and Ise Saburo, though their true identities remain unknown. Around the same time, Kogoro Mouri travels to Kyoto with Conan Edogawa and the others at the request of Ryuen, a monk from Sannoji Temple. Eight years earlier, a secret Buddhist statue—the Medicine Buddha, which is revealed only once every twelve years—was stolen from the temple. Recently, the temple received a mysterious drawing believed to indicate the statue's location, and Kogoro is asked to decipher it. At Sannoji Temple, the group meets several individuals connected to the case, including the monk Enkai, antique art dealer and temple patron Sakura Shozo, Noh actor Mizuo Harutaro, and used bookstore owner Saijo Taiga. While searching for clues related to the drawing, Conan visits Gojo Bridge, a location historically associated with Minamoto no Yoshitsune and Musashibo Benkei, where he encounters Heiji Hattori. Heiji is independently investigating the Genji Hotaru murders, and the two decide to cooperate. During the investigation, Heiji recounts his first love: a girl he met in Kyoto eight years earlier, who was wearing a kimono and singing a temari uta (traditional Japanese ballad) at a temple. He also mentions a crystal ball he picked up at that time, which he continues to carry as a keepsake. Conan and Heiji later travel to Mount Kurama, where they are attacked by an unknown assailant wielding a bow and arrow and wearing a motorcycle suit. That night, Sakura Shozo is murdered at a teahouse in Ponto-chō. Shortly afterward, Heiji is attacked again while escorting Kazuha Toyama home. The assailant challenges him to a duel using wooden swords, and Heiji is severely injured and hospitalized. Conan eventually deciphers the code in the drawing and determines that the Medicine Buddha statue is hidden at Bukkoji Temple. When Heiji arrives there, he receives a phone call from the culprit, who reveals that Kazuha has been kidnapped and orders Heiji to come to Gyokuryu Temple on Mount Kurama. At Gyokuryu Temple, Heiji confronts the criminal and identifies him as Saijo Taiga, who is revealed to be Musashibo Benkei. Saijo orders his disciples to attack, but a man disguised as Heiji intervenes, later revealed to be Shinichi in disguise. The real Heiji soon joins the confrontation, allowing Kazuha to escape with him into a room within the temple. There, Heiji discovers that the legendary sword Muramasa is hidden inside a chest of drawers and uses the temari uta sung by Kazuha to locate it, challenging Saijo to a final duel. Meanwhile, Shinichi briefly reunites with Ran Mouri before reverting to Conan. Conan assists Heiji during the final confrontation, disarming Saijo, who wields two swords—o ne of which is coated with deadly poison — and ultimately defeats him, bringing the case to a close. The following day, Kazuha sings the temari uta, prompting Heiji to notice an error in the lyrics. This realization leads him to discover that Kazuha herself is the girl he encountered eight years earlier, confirming his first love. Separately, Ran notices lingering sweat stains on her handkerchief from her brief meeting with Shinichi, convincing her that the reunion was real and not a dream. ==Cast==
