The pint-sized detective partners up with the ‘Great Detective of the West’ for a perfect combination of super sleuth crime solving!  Conan is invited to Osaka to meet up with Heiji Hattori, a teen detective whose deduction skills are on par with Shinichi Kudo!

But with a serial killer on the loose, it looks like sightseeing will have to wait! Later, at a place called Mermaid Island, a woman is found hanged under a waterfall.

It seems the legendary mermaid’s curse has struck again… unless Conan and Heiji can find an all-too-human culprit!  

The crime solving duo of East and West come together in this two-part special!
