Natsuki Sakurai has been serious ever since she was born. She likes profit in her business, that was until her company was fined heavily for fraudulent and she was the company's scapegoat. After she was ultimately fired, the company went under months after due to failure internally and filed for bankrupcy. She now owns an auto shop and usually stresses out to keep her customer satisfied, as well as her employees, and making sure they are doing their job. Her schooling history is unknown, however, she knows how to get the job done and is intelligent. Natsuki typically stays by herself and doesn't usually interact well with others. She doesn't care much about bonding with her employees, even though they try to get her to open up a bit. Sakurai stands at 164 cm (5 ft 4.5 inches) and weighs in at 50 kg (110 lbs). Her sex life is unknown either, though it is said that she knows her ways.
