The epic confrontation between S-Class heroes and monsters from the Monster Association continues — both in the dark underground labyrinths and outside. In the next volume of the ultra-adrenaline manga about Saitama and his one punch, noble heroes descend ever lower like moths drawn to a flame. They will get tangled in the hair of the Long-Haired Demon, appreciate the liveliness of the Black Sperm, feel the power of the homeless Emperor's hatred, behold the vacuum elephant absorbing others' superpowers, experience the "Cat Punishment" of the Cat, get caught in a fight with the Right Arm, throw a bone to the Little Overgrown, and sweat from the battle with the Evil Mineral Water... Their name is legion, they are monsters, and they all must be defeated to reach the light. But there is no end to this nightmare...
The book includes chapters 107–118.
