I dare to say it is better than the first act. The story fully continues, it is not an "added" story. Sometimes it runs so fast one wonders where is this story going to go. Great twist plots, most of them credible and it does not unfold as one could imagine. No doubt the writer Buronson did his best to rip off the audience's heart.
There are usually false spoilers as an advance of the next chapter, maybe wrong translations, who know, so i prevented from watching those.
Great story but so cruel to the feelings not because of the violence but about the story itself, heartrending, i say so because one find HNK to be a love story. Apart from the superior love expressed through the forgiveness I can not agree that a last minute contrition could save the worst evil man in such a way he becomes a martyr of love. Hard to swallow.
The story does not end with the last ova chapter, the manga still have some story left so if interested check out the internet to see how it really ends, and then check out for the ova "Shin HNK".
At the end maybe you will feel the same lump in the throat as me. I still wonder what if not love is then the motivation underlying Ken? Mr Buronson was heartless about Lynn, too much.
