About

The world has changed. Unlike the past, people now use what are called 'Abilities,' and their rank is determined by the utility and range of those powers. Most F-ranks have such pathetic abilities that they can't get commissions, so they end up working at construction sites. Then one day, a woman with black hair, red eyes, and a fierce expression—wearing a tight blouse and a black high-waisted skirt—is assigned to the site as a supervisor. Most of the men drool over her body, but she is incredibly rude. Even if they want to talk back, she's an E-rank... Should they endure it, or teach her a lesson? That depends on the F-ranks.
