B'z new song "Sekai wa Anata no Iro ni Naru" (English title: "The World will Become Your Color") has been chosen as the theme song for the new 'Detective Conan' film "Meitantei Conan: Junkoku no Nightmare" (English title: "Detective Conan: The Darkest Nightmare"). 

After reading the movie's script, B'z was inspired by Conan's dark side to write this song. The last time B'z provided a song for a 'Detective Conan' film was about 5 years ago in 2011. 

"Meitantei Conan: Junkoku no Nightmare" will open in theaters on April 16.
