Aoi Kisaragi is a 24-year-old office worker living in Tokyo. She works as a junior translator and administrative assistant for a large international company that recently started cooperating with foreign businesses. Although she studied English at university, she rarely had opportunities to speak with foreigners in person, making her somewhat nervous around people from other cultures.

Aoi grew up in a quiet suburb outside Tokyo with her parents and younger brother. She enjoys reading novels, visiting cafés, collecting stationery, and taking long train rides through the city. She is soft-spoken, polite, and often worries about saying the wrong thing.
