Never underestimate Japan anime industry to completely miss the mark in their ending failing to connect the story by the end and miss the mark on emotional moments. If you don't build it up you don't force it in. It was decent at some point but they completely drop the ball in terms of satisfaction and closure of every plot line. Making the kid a main character is a decision itself. What a "great" character he is, how much he "contributes" to the story. Don't worry guys we'll do more "Dororo" because who doesn't want a little kid being a main character for an edgy killer character while actively doing nothing but whining.
