Detective Conan's ending has always been controversial, but based on current information, we can make some guesses about the grand ending. Conan and Haihara will be together. Aoyama Tsuyoshi once said in an interview that Haihara was one of his favorite characters and that he did not want her to leave Conan. Therefore, if Aoyama Tsuyoshi really drew the ending of Detective Conan, Conan and Haihara might be together and have a happy ending. Conan will find the truth and uncover the secret of the Dark Organization. Currently, the Dark Organization has always been the focus of the plot. Conan has been looking for clues about the Dark Organization. If Conan could finally uncover the secret of the Dark Organization, he might become a hero and win people's respect. Conan will not solve the problem of the Dark Organization but will end peacefully. Aoyama Gangchang revealed in an interview that Detective Conan was not a work that solved cases but a work that told stories. Therefore, if Conan does not solve the problem of the Dark Organization in the end, he will still end peacefully because he has injected enough emotion and suspense into the story. These were just speculations about whether Aoyama Tsuyoshi would show his creativity in Detective Conan's ending. It was still up to him to decide. No matter what, I hope that Detective Conan's ending can give the readers the best experience.
