ENG DUB * ONE PUNCH MAN SEASON 3 (PART 1) VOL.1-12 END + ONE PUNCH MAN : SPECIAL 02 VOL.1-6 END

STORY:

Saitama is a hero who only became a hero for fun.
After three years of “special training,” he’s become so strong that he’s practically invincible. In fact, he’s too strong—even his mightiest opponents are taken out with a single punch. Alongside Genos, his faithful disciple, Saitama performs his official hero duties as a member of the Hero Association.
One day, monsters claiming to be from the Monster Association suddenly appeared, taking a child of Hero Association executive hostage. The S-class heroes gather and plan a raid on the Monster Association hideout to rescue the hostage. Meanwhile, Garou, a “human monster” who was taken by the Monster Association during a battle with the heroes, awakens in the Monster Association hideout.

興趣使然而開始當英雄的男人，埼玉。
經過3年的特訓，他獲得了能將任何敵人一拳打倒的無敵力量，與偶然成為徒弟的傑諾斯一同加入英雄協會這個職業英雄所屬的組織，展開每一天的活動。
某一天，自稱怪人協會的怪人們突然現身，也將英雄協會幹部的孩子挾為人質。
為了搶救人質，S級英雄們齊聚一堂，商討闖入怪人協會據點的戰鬥計畫。
