If you loved Detective Conan: Episodio uno - El detective que se encogió, try Detective Conan 13: El perseguidor negro
Un puente entre una película que ya has visto y una que casi nadie ha cruzado. Esto es lo que comparten, y lo que la segunda hace que la primera no hace.

Detective Conan: Episodio uno - El detective que se encogió

Detective Conan 13: El perseguidor negro
Lo que comparten
Both films are directed by Yasuichiro Yamamoto, and they both carry the foreign gem mood tag, and they sit in Animation / Crime / Mystery territory. If that's the register that drew you to Detective Conan: Episodio uno - El detective que se encogió, the second film will land in a comparable space — through a different lens.
What Detective Conan 13: El perseguidor negro is
Nagano Prefecture. A crow's feather. Six murders across Japan connect in a disturbing pattern. Conan Edogawa realizes a Black Organization spy is embedded with local police. Gin's assassins close in. See it for the puzzle-box plotting, stay for the sheer anime audacity.
