Series Synopsis
The world has many strange and powerful monsters threatening the peace of daily life. It is the job of the Heroes Association to counter the never-ending onslaught. This is also a good way for someone to win praise, recognition, and job security. With an ever-growing roster, the Association is ready to face any potential disaster.
Alternatively, the Earth can rely on the one man who chooses to be a hero for fun.
Saitama (voiced by Makoto Furukawa) has always had a strong sense of justice. Though a bit of a derp, he's the first to jump to anyone’s rescue. On a whim, he made the decision to train his body to fight the forces of evil.
As a result, Saitama transformed himself into the most powerful hero in history. He now has the strength to defeat any enemy with a single punch.
Yet the Association’s rigid bureaucracy has left Saitama as a relative unknown. However, his abilities have not gone unnoticed. He even manages to find a disciple, the cyborg Genos (voiced by Kaito Ishikawa).
When all other heroes fail, Saitama is the only one who can do what they cannot. And he makes it look easy.
