I've read this Detective Conan manga Chapter 499-504 there's a case when Conan chasing Rena Mizunashi, the CIA agent that disguise as Black Organization member with code name Kir. She along with Korn and Chianti is assigned to kill Mayor Candidate (I don't remember his name).
In that time, Conan's tracker is stick to Kir's shoes and he heard the code about the place where the Black Organization plan to Kill the Mayor.
Conan realize that the place is Hyde Park, and he said it's not really Hyde Park that located in London but in Haido Park. But I'm still not understand why can Hayde Park become Haido Park, is anyone can explain about this?
