Meitantei Conan Movie 23: Konjou no Fist

Ran and Sonoko travel to Singapore to watch Makoto Kyougoku compete in an international karate tournament, while Conan should have been left behind in Japan. Kaitou Kid has other plans: he secretly smuggles Conan into the country and forces him to use the false identity Arthur Hirai while Kid pursues the legendary blue sapphire known as the Fist of Blue Sapphire.

A murder at Marina Bay Sands, a bloody warning card, and a wealthy man's interest in the gem draw Conan into a conspiracy that reaches far beyond a simple theft. Kid must also contend with Makoto, whose unbeaten karate makes him a terrifying obstacle, while Conan races to uncover the truth before the schemes surrounding the sapphire place all of Singapore in danger.
