I think I read this before watching the Netflix version of this. Both the Manga & Netflix adaption is actually decent. There are slight changes in the Netflix series, but it doesn't take away from the storyline. It adds more depth to the characters. Definitely watch the Netflix version of this before or after you read this. Here you will find a collective group that acts somewhat similar to the American drama series Dexter. There is subtle gore done with intention. Each individual puts his talents to use towards the group handling special underground requests. This series is unique in how these men go undercover & carry ontheir business.

Gives you another perspective of the Yakuza world.
