Conan will outlive 90% of its readers. And probably their children or even grand children too.
Without Aoyama Conan wouldnt do.
Imagine the ending and every (canon/had a proper introduction) character is somehow even just a bit actually is related to BO even if its not directly and every detail is a fragment of the whole puzzle and when all pieces fits it'll just make sense (kinda like how they revealed the boss of BO and that he already made a cameo a few hundred episodes before ,when a forgotten character that didn't even seem that important suddenly has a role) well its prob not this but honestly idc how the final chapters would be actually i might even feel empty once it ends as long as its fun idc how it ends
Aoyama said: I could bring this story to an end without introducing new characters, but why should I? So here is this new character who will probably be useless as much as the others, but who cares
