I have always found myself attracted to yakuza type stories, somehow this came to my recommendations and I feel supremely grateful that I read it. The storytelling, the art, the character development- everything is a 5 star, thus making it a completely complete manga. It's a story of two assassins from different times, one fighting with demons from his past and another with his present. When these two crosses road, a new story of hope begins.
