Well fans of Detective Conan were probably surprised when after the Detective Conan episode 554 aired that Mouri Kogoro's voice had changed.No it wasn't puberty, Kamiya Akira was dismissed from the show. Kamiya did not release the reasons why, but admitted that it was mainly he who was to blame.

Kamiya Akira was replaced with the voice actor Rikiya Koyama. It takes some time to get used to the voice, but Koyama will soon grow on us all!
