In Detective Conan, who were the members of the Black Clothes Organization?

Was their contact method Seven Children or Seven Ravens? Did 'Song of the Seven Sons' refer to the song 'Seven Children'?
Many people said it was Seven Ravens, because it could be deduced that ravens were black birds with black feathers.

Answer 1

If you want to experience the hardships of surviving in the Black Organization, you can read the book " Conan's Survival to the Destruction of the Black Organization." The protagonist, Uesugi Sawa, had been lowering his posture and surviving many missions of the organization in order to reduce the possibility of being discovered. If you want to understand the activities of the black organization behind the scenes, you can watch " The Boss is not a science ". The protagonist, Karasuma Shuyoshi, is the BOSS behind the black organization, but because of amnesia, he became an ordinary bar owner, causing many people to misunderstand his identity. If you want to see the story of the Black Clothes Organization being defeated, you can watch " Detective Conan: Destroying the Organization in One Year ". The protagonist, Mo Jinche, was asked by the system to overthrow the organization within a year to test his skills and courage. The above is my personal recommendation. I hope you like it.
