One Punch Man Manga Chapter 21

The Monster Association has infiltrated the Hero Association and the heroes are struggling to wage counterattacks. The Monster Association’s goal is to annihilate humanity and they are doing so small but sure. The heroes are overwhelmed and outclassed and will be crushed soon enough, if not today. Orochi is the leader of the Monster Assocation and is an all-powerful monster that is nearly impossible to kill. The heroes are in desperate need of Saitama to show up and help them, but he is nowhere to be found. The Monster Association is slowly but surely getting a grip on the world, and it is only a matter of time before they succeed.
