Landlady

The unnamed Landlord is the owner of the building where Saitama lived at.

Appearance
She is a short, elderly lady with short grey hair and wrinkles. She wears a purple jacket over her yellow turtleneck and wears sandals.

Personality
Something of a cold blooded woman, she has absolutely no qualms about hosting a gang of criminals in her building so long as they pay their rents on time, and became enraged enough with Saitama for defeating the criminals for their bounties enough that she kicked him out after taking all of the money he earned.
