One Punch Man Manga Chapter 21

The Monster Association has infiltrated the Hero Association, leaving the heroes struggling to mount effective counterattacks. Their goal is the complete annihilation of humanity, carried out steadily and ruthlessly. The heroes are outclassed and on the brink of defeat. Leading the monsters is Orochi, an immensely powerful being who is nearly impossible to kill. Humanity’s only hope lies in Saitama, yet he is nowhere to be seen. With the Monster Association tightening its grip, it’s only a matter of time before their plans come to fruition.
