Great series especially if you're into S&M type stuff. Very intriguing plot and I genuinely enjoyed it for the most part. Most of the characters are interesting and well fleshed out. The art style is great too. However, there is a huge gaping plot hole that I don't get. They know that this guy can insta beat anyone in a duel right? Why not just take our your chip right before a known confrontation and physically beat him to death. Easy solution. It even says slaves can go without the chips for short periods so I just don't get it.
