In her school days, she was interested in animation, so she joined a club. Along with her four friends, they created an animation titled "Shinbutsu Konkou Shichifukujin," which was to be shown at their high school's cultural festival. During production, everyone played their roles in order to complete the project. However, it is revealed that Aoi is not the greatest at drawing, computer graphics, script writing, or voice acting. Before graduation, the girls made a promise to reunite one day and create another anime altogether. They set this creed in stone by sharing donuts. It seems that everyone has their minds set on what they want to pursue in the anime industry. As for Aoi, she graduated without a specific goal in mind, and came to Musashino Animation to work as a production assistant, immediately getting involved in her first anime, Exodus!

After her first year as a production assistant at Musashino Animation, the company is hired to work on an anime adaptation for a manga titled "The Third Girl Aerials Squad." At this time, Aoi is promoted by director Seiichi Kinoshita to her new position as Head Production Assistant after her colleague, Yutaka Honda, resigned from the company to pursue his dreams. This deals a great amount of pressure on Aoi, as she is immediately overwhelmed by the tasks involved in her position.

Aoi seems to have a bright and cheerful personality and she always strives to stay positive, no matter how murky the problem. She is also hardworking and cares a lot for her friends and always tries to stay calm in stressful situations, and she is also a very energetic girl.

Although a fresh face at Musashino Animation, she quickly learns how to cope with the everyday stresses of her job. Her diligence and determination to find a solution to every predicament has garnered the respect of many of her colleagues and acquaintances in the industry, alike. She is very persistent and patient when caught in between predicaments at work.
