I believe that friends familiar with "Detective Conan" should know that there is such a person who appears very rarely, but in the quiet of each appearance, he himself will become a laughing policeman, he is gunma prefecture policeman Yamamura Fu. Many viewers' impression of Yamamura Fu often stays in his own funny attributes, and every time he meets Conan and others, he can always make some jokes, so he has also become a confused policeman in the eyes of the audience, but what few people know is that Yamamura Fu is also one of the few lucky people who rely on Conan reasoning to be promoted from a criminal police officer to a police department.
Yamamura's debut in Desperate Detective! In "Two Consecutive Killings", there is a criminal policeman who seems to have little self-confidence, according to his own introduction, it is after watching "The Dangerous PoliceWoman Story" starring Kudo Shinichi's mother, Fujie Yukiko, that he decides to become a criminal policeman, and in the story is a clumsy criminal policeman with a timid personality and lack of reasoning knowledge. I don't know if it's because of his personality, every time Aoyama arranges for him to appear in a case, he will involve some ghost-related cases to show his funny role in the process of handling the case.
In the eyes of many viewers, this character's insight and reasoning ability are incredibly poor, and it is not suitable for criminal police at all, even Conan bluntly said that this person is a rookie policeman, and I even wonder how this person became a criminal policeman, maybe there is really an element of luck in it.
In the next few cases, because Yamamura Fu is very easy to get carried away, as soon as he is touted, he has become an excellent object for Conan to use anesthesia gun, and his position has changed after Conan used Yamamura's voice to break several cases, and in the theatrical version of M13 "Dark Tracker", Yamamura Fu's police rank has also been promoted to the police department, becoming the same level of police rank as Officer Mutsumi, which surprised many people, and I have to say how lucky this person is, it is really unexpected.
On the other hand, the longest resident criminal police officer Takagi, Sato police officer and other people in "Detective Conan" have also cracked many cases after their appearance, but the police rank has not been promoted, I don't know if Aoyama Sensei has plans to promote them to the rank in the follow-up, otherwise with Takagi's personality, the police career may be difficult to make progress, after all, this person's luck is not good.
