Suiryu is a Martial Artist and user of the Void Fist. He is said to be a top contender in the Super Fight tournament. Suiryu is an easygoing and carefree man usually seen smiling and is a notorious playboy, who would rather spend time with women than training. He is also very eager to fight strong opponents and believes the reason for fighting is to live an easy life without worry. During fights, Suiryu holds back in an effort to make any fight more interesting, only using his legs during his fights and later defeating his opponents with one kick. While fighting he tries to make small talk and after he defeats his opponents, he sarcastically apologizes to them for being too strong. Suiryu is a martial arts prodigy. Despite having spent most of his time goofing off or not taking his lessons seriously, he still ultimately became one of the most revered martial artists in the world, considered a legend for winning four Super Fight tournaments in a row.

Saitama has a rather peculiar hobby, being a superhero, but despite his heroic deeds and superhuman abilities, a shadow looms over his life. He's become much too powerful, to the point that every opponent ends up defeated with a single punch.
 
The lack of challenge has driven him into a state of apathy, as he watches his life pass by having lost all enthusiasm, at least until he's unwillingly thrust in the role of being a mentor to the young and revenge-driven Genos.

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. Now, the great seer Madame Shibabawa’s prediction about the Earth being doomed seems to be coming true as the frequency of monster incidents escalates. Alongside Genos, his faithful disciple, Saitama begins his official hero duties as a member of the Hero Association, while Garou, a man utterly fascinated by monsters, makes his appearance.
