Classical story of fallen hero that redeems himself by taking care of a child. You´ve seen it countless times in different mediums. And when done correctly it can work pretty well.
But Case 3 does not do it very well. The characters are all extremely one-dimensional. Even Kougami, who is a very interesting character in the first and second seasons, gets here reduced to just "revenge is bad so I won´t kill anyone anymore". And he takes that motto to ridiculous lengths.
One also wonders why someone who is renouncing violence travels to the hottest warzone in Asia. It really makes no sense. This story would work much better if he was running AWAY from violence, and violence found him anyway. But instead he´s travelling from warzone to warzone! Retarded.
Then you have villains whose plan reminds me of the South Park gnomes business plan:
1 - Collect underpants
2 - ???
3 - Profit
I´m still scratching my head trying to understand what was the villain plan and how doing what he does is supposed to make him rich.
While Case 2 could have greatly benefited from additional 30-40min or running time, here in Case 3 I was glad the nonsense was over quickly.
The final action scene is cool, so I guess there´s that.
