About the juvenile detective team, it's not as worthless as you say. Step beauty is innocent, Hirohiko is kind and delicate, and Yuan Tai has an amplifier.

They are the representatives of childhood in Detective Conan. After all, Conan and Ashala are both adults with extraordinary experiences and different circumstances, which makes Conan's atmosphere somewhat dull, and they are not easy to show childlike innocence.

The emergence of the juvenile detective team is just right. They have extraordinary cohesion, and it is perfect to combine them with Conan and Ashwara!

Feeling with heart and positive attitude, the juvenile detective team is very cute. After all, even Conan and Ashala are one of them.

I don't know if you have seen the theatrical version 9, if not, just have a look, which may save your understanding of the juvenile detective team!
