What is the significance of Conan's existence?

I think it has created a lot of relaxed and active atmosphere for Conan's plot development. As we all know, Conan and Haiyuan Ai have been appearing on the screen as primary school students for many years, so as to hide their identities from the black organizations. However, these two people are adults after all. If you are really a primary school student, you will definitely feel too bored.

Conan, in particular, will never forget to be reasonable at any time and place. His hobby also influenced his good friends around him, so he and his classmates formed a juvenile detective team. There is no doubt that Conan is the spiritual leader of this group, and Haiyuan Ai is a technical consultant, so Bumei is naturally an ordinary member.

For them, the juvenile detective team is more like a game. In their eyes, both Conan and Luyuan seem to have smart brains and don't look like their peers. I believe all three of them are skeptical about this, but they still don't know what happened. But these three real children are very willing to follow Conan to explore. However, children are children after all. They have no outstanding skills. Most of the time is filling the field or playing soy sauce. So in the eyes of some viewers, they became jokes, and some even thought they were a thorn in the side.

However, when everyone is in danger, because of the nature of children, these three people sometimes seem really naive. If they don't do well, Conan and them will be stopped. However, some impatient viewers can't stand this. They don't think these children should always appear at critical moments. They always make people feel that they have accomplished nothing and have more than they have lost.

Some viewers may think there are too many people, but Conan is an animation after all, and many viewers are teenagers. This kind of role arrangement is more in line with the life of teenagers. Although they are sometimes naive, they also create a lot of relaxed and active atmosphere for Conan's plot development. They also have a very important role, which is to make up for the lost childhood of Zuyuan. So I think it has created a lot of relaxed and active atmosphere for Conan's plot development.
