Sword of the Eight-Headed Serpent

Part 1: Conan, Ran, and Kogorou go to the mythical village of Izumo. there they meet Eiko Ezumi, an employee at the Grand Shrine, and learn that she is to marry a rotten businessman, Kouji Wanibuchi - founder and president of his own company. Later they meet her childhood friend, Ryousuke Fukuma and it comes to a rocky start when Kogorou yells at him. The next day, Eiko's fiancee is found dead with his Sword of the Eight-Headed Snake he was carrying goes missing. The police have 4 suspects, 2 of whom are Eiko and Ryousuke, and Takehiko Fujie and Kazuya Ishitobi. Eiko's and Ryousuke's alibis don't set right with Conan who takes Ran to investigate the alibis.

Part 2: Conan proves that Eiko and Ryou's alibis were to protect the other. Ryou finds Eikos pendant at the crime scene and thinks it was her and Eiko thought it was Ryou from his alibi that he was where she really was, the train station, but she didn't see him. Then it turns out that Ishitobi and Fujie went to Eiko's home to convince Wanibuchi to spare their businesses. Eiko realizes that her pendant vanished that same night. Ishitobi's alibi checks out when the police discover that he is charged with a D.U.I - Drinking Under the Influence. At the temple registry, Conan notices something that helps him figure who the culprit is. Conan tricks Fujie and Kogorou, by impersonating their voices to the other, to meet in front of Hinomisaki tower where Conan tranqs Kogorou and solves the case. Conan (as Kogorou) reveals that from Fujie's testimony that Wanibuchi was a snake, was a correlation to the myth of the Eight-Headed Serpent. He used Eiko to cover his tracks with her pendant, and arranged Wanibuchi & Eiko to meet at the cave around 1:00 and 1:30. His trick to cover the time difference was that he went to the castle twice. He falsified his registry time by putting an added time slot, replaced the pen with an erasable, and placed his name after the murder. To prove this all, Fujie put "Narisei City, Tokyo" as an address for a false name, and it turned out that Narisei isn't a part of Tokyo anymore and confesses. Afterwords, Kogorou tries to get his coin stuck in the Izumo Knot to "bring true his wish", only to make all the coins in the knot to fall on him.
