A master piece. We are able to see a character that is not good or bad, is just a human. His internal power and motivation came from help others to avoid mistakes. Here we are in presence of a real Sensei. The love and respect put in this series demonstrate that nobody needs to "subvert expectations" and all that arrogant bs, to pretend to be a genius director. You need instead, talent, love and respect. Well done. I love the show.
