It's a collection of stories which follow chronologically with a hero who shows us a different side of life in Japan. Makoto immerses us in gang stories, yakuza, and resolves business with notoriety in the community. I enjoyed this immersion in this world, and immersion in gang life is quite rewarding. After reading this novel, which was adapted into manga, I learned that the version in drama (Japanese series) is being output. See the TV series brings another vision of the book, certainly a little modified, but with a little more humor. In short I recommend it to any fan of Japanese culture!
