I reckon you'll have at least seen the two movies before this one. So I don't consider it spoiling talking about things that happened before this movies events. Like the fact, that our main character swore to not kill anymore. Something difficult to hold up, especially if you consider how many people are out to get him.
After that cliffhanger from the previous movie, we do get an introduction to that character we saw at the end. And it's a pivotal character to say the least. Since I'm not aware of the Manga or Anime made before this, I can't compare anything. I do know that the dynamic of the movie works nicely. Also the action scenes are really well choreographed (like the previous one). It might be a bit too long with its running time, but it's still very entertaining
