Saitama has a twin sister who is the complete opposite of him. She has a job, she's smart and has hair unlike his bald brother. And that includes her being weak unable to protect herself. Luckily Saitama as the older sibling, protects her from monsters in City Z. 

While Saitama went looking for the leader of the paradise group, she went out to help him, but she encounters someone else there...
