Does anyone know the true identity of Haidong Kuroha War (Kid, Kuroha War) in Detective Conan?

Koizumi Akako, as a witch family. Remember the famous detective party in 2 19! Kudou Shinichi VS Blackfield Haidong. . . Koizumi Akako almost showed that she knew. . (That episode is a place where Qing Zi and Kuaidou are full of memories. . . )。

As for the others. . . . I won't. The boy is not like Shinichi, so many people know his identity. Qing Zi certainly doesn't know ~ because no one can see the child's face yet ~

Except, of course, the juvenile detective group. . . It's a pity that they regard Kuaidou as their new brother. . Even after thinking about it, Conan will only say that he has become Kudo, so only parents and old servants, that is, Hiroko, know the identity of kid.

I just saw a new problem in lz. . . About this. . Um ... . . It should be because the code name "kid" was a mistake, and 14 12 was regarded as kid, so I went to Xiao Xinyi, when Kuaidou's father was Kidd. He said "we are brothers" because his name "child" was a mistake. . . . I don't know if I can understand this,,, to see the adventures of 472 teenagers in Kudou Shinichi (Part I) and 473 teenagers in Kudou Shinichi (Part II).
