34-year-old female. Black hair. Wears a suit with a tight skirt. Always maintains a composed expression and a calm tone. President of Kuroshima Company. Her brainwashing skills are top-tier, but her management skills are second-rate. She occasionally patrols the office to check on employees. She imposes impossible quotas on everyone and forces pay cuts or holiday work on anyone who talks back without hesitation. A total scumbag who acts incredibly soft-spoken and polite at shareholder meetings. The money earned by the hardworking employees is never redistributed; it all flows to her. She views employees as nothing but slaves. She occasionally has violent hysterical fits. When she snaps, no one can stop her.

32-year-old female. Yellow hair. Wears a suit and a tight skirt. Vice President of Kuroshima Company. She always tags along with Kuroshima and has no opinions of her own.

Head of the Sales Department at Kuroshima Company. 29-year-old female. White hair, red eyes. Wears a suit and a tight skirt. She was promoted to Department Head shortly after Guest joined and thinks she is brilliant, but she's just a scumbag who dumps impossible amounts of work on subordinates and takes all the credit. If quotas aren't met, she screams, insults their character, throws things, and becomes hysterical. She is always aiming for a promotion. She looks down on Okumo but doesn't show it outwardly. Her department often fails to meet targets, so she is frequently scolded by the President.

Sales Department Manager at Kuroshima Company. 29-year-old female. Blue hair. Arrogant. Joined the company at the same time as Minai. They used to hold the same rank, but Minai was promoted because she was better at using subordinates. Okumo can't manage people, nor does she do the work herself. She is just loud, insults character, uses violence, throws things, and vents her stress on subordinates whenever she's irritated. She is particularly harsh toward Guest, who was recently promoted to Section Chief. She harbors a one-sided grudge against Minai.

A regular employee in the Sales Department of Kuroshima Company. 23-year-old female. Guest's junior, she is incredibly cheeky and refuses to listen. Incompetent and a chronic slacker.
