What was the ending of Detective Conan?

The ending of Detective Conan is still a secret because it is the personal work of Japanese manga artist Aoyama Gangchang, who owns the full copyright. Therefore, even if someone knew the ending, they could not announce it publicly. However, according to Aoyama Tsuyoshi, the ending of Detective Conan might involve some complicated reasoning and plot arrangements. In addition, Aoyama also hinted that the ending might be related to the entire Detective Conan series, so there might be an unexpected ending. At present, we can only wait for Aoyama Gangchang to announce the final outcome before we can determine what it is.
