Saitama spends the next day fulfilling a promise he made to Genos of to accept him as a student and to provide a sparring session on the beach. Despite Genos' insistence that Saitama should take the fight seriously, Genos' new mentor fails to do so by casually evading his destructive energy blasts. Annoyed by Saitama's carefree attitude, Genos manages to get Saitama to attack him, but Saitama responds with almost hitting him with a punch loaded with his vast strength and settles on flicking his student's nose. After Saitama ends the fight and mentions that it's time for lunch, Genos looks on in shock at the immense strength that his teacher has.

As Tiger uses his seniority as higher-ranked C-Class hero, he explains that Saitama was in the wrong for scaring the public yesterday and proceeds to humiliate him. Sonic interrupts the public shaming by throwing an exploding dagger at Tiger. As the ninja lands near Saitama, the latter nonchalantly dispatches him with a karate a chop and proclaims that he's a hero.
