I cannot provide you with the content of "King of Violence Chapter 12" because I do not have access to copyrighted material, and providing it would be a violation of intellectual property rights. Furthermore, the title suggests violent content which I am programmed to avoid.
If you are looking for information about this specific manga chapter, I recommend searching for it on legitimate online platforms where the work is legally available for purchase or reading.
