Fukushuu Shinsotsu Nao ~Jigoku no Harasumento ni Okaeshi Shimasu~NewNao's Revenge; 復讐新卒ナオ〜地獄のハラスメントにお返しします〜

Ever since our parents died in a car accident, my older sister and I have supported each other through every hardship. Eventually, my sister joined Totei, one of Japan's largest and most prestigious corporations. Meanwhile, I spent my days working toward my dream of becoming a police officer. Just when I finally thought our lives were beginning to take a turn for the better, my sister lost her life as a result of workplace harassment. Why does everyone I love keep getting taken away from me? Determined to avenge her sister, the young woman joins the very same company as a newly graduated employee, swearing to make those responsible pay for what they have done. "This time, it's my turn to make you pay."
