Kaito Kid's notice letter appeared in the collection of the Axue Zaibatsu in Hakodate, Hokkaido. This time, Kid is going to steal the Japanese sword of Hijikata Toshizo, the deputy leader of the Shinsengumi during the Edo Shogunate. Kaito Kid, who has always pursued luxury gems, actually has his eyes on swords? At this time, Hattori Heiji, known as the famous detective of the West, and Conan and his party also came to Hakodate because of the kendo tournament. On the day when Kid carried out the notice, Heiji saw through Kid's disguise and chased him relentlessly! At the same time, a body was found in the warehouse street of Hakodate with a cross wound on the chest. During the search, a Japanese-American arms dealer active in Asia called "Merchant of Death" appeared. This person has been looking for the treasure hidden in Hakodate by the first head of the Axue family.

This treasure seems to be inextricably linked to the sword that Kidd is chasing and trying to steal. While Kidd is aiming at the sword, a swordsman is also approaching Kidd...
