Plot

Part one

Conan's class finds a wallet with a message from Ran ten years ago. Conan shares the story of how it got there by explaining the adventure he had in the past. Ten years ago, Shinichi and Ran enter the school at night to investigate the rumors of a ghost. They run into a mysterious man who claims to be Shinichi's younger brother who challenges them in a treasure hunt; He then hands them a wallet with a letter containing the message "Quell the anger of Haido" in kanji. "Quell the anger" is pronounced the same as "Drop the anchor", the riddle refers to Haido Port. The pair finds another riddle hidden on a fire hydrant which contains the message "Clear the allegations against Toriya and demolish the liver of Goroukou" in kanji. Conan reveals that clearing the allegation is to prove innocent meaning to prove White (白, Shiro?) which refers to the word Castle (城, Shiro?) meaning Toriya castle. Goroukou is a reference to Mito Kōmon (水戸黄門?). Destroying the liver means destroying the middle, so removing the middle kanji of Mito Kōmon yields Suimon (水門?, lit. Flood Gates). The pair finds the next clue near a railroad track by floodgates of Toriya Castle; The message on the riddle is "Erase this Mark. With a raspy voice, endure loneliness."

Part two

Shinichi solves the riddle and heads to the school and finds the next riddle on a stop sign. The letter contains a mixture of kanji, and mahjong symbols and when read, pronounces Beika City Hall. Once there, Shinichi finds a sign on a pole with the message "S → W". Shinichi presumes it means the sunset and assumes his father created the riddle for his entertainment. Back in the present time, Conan realizes what the riddle actually means. Conan writes down the symbols for port, castle, flood gate, post office, middle school, and city hall. It is revealed "S → W" means South to West, so when the symbols are turned 90 degrees, reveals Ox hide in kanji. Conan rips open the leather wallet which reveals a message for Yusaku Kudo from the original Phantom Thief Kid, a single question mark. In the past, Yukiko Kudo is having dinner with Toichi Kuroba and hands him a letter from Yusaku which contains a single exclamation mark; revealing he received Toichi's message and knows his true identity.
