I have been reading these debates if we are going to change or keep the title. To me, I don't care which. If we are going to change it, we should replace "Case Closed" into "Detective Conan". If we keep it however, we should change "Detective Conan" to "Case Closed" for The Time Bombed Skyscraper, The Fourteenth Target, The Last Wizard of the Century, Captured in Her Eyes, and The Phantom of Baker Street.
