Meitantei Conan: 100-man Dollar no Michishirube

A message from Kid the Phantom Thief announces his intent to steal a Japanese sword from the Onoe Family in Hakodate, Hokkaido. Conan and Heiji Hattori, already in the area, investigate. The Onoe Family's collection is linked to Toshizo Hijikata, a historical figure who died in Hakodate. The family lawyer is found murdered, seemingly killed by a Japanese sword. A suspect is an investor and arms dealer believed to be seeking a hidden treasure of the Onoe family. The grandfather of the family patriarch had ties to the military industry during wartime and was rumored to have concealed a weapon capable of altering the outcome of war in Hakodate. The connection between Kid and the weapon remains unclear. Meanwhile, Heiji searches for the ideal spot to confess his feelings to Kazuha. The pursuit of the treasure begins amid cherry blossoms in the north.
