Najimi is a young girl who, after losing her job, decides to switch professions and starts attempting to create doujinshi, or fan-made manga. She was inspired after seeing her friend Tsuyuri sell her doujinshi at a comic festival, and after meeting her childhood friend Justice again, who is also a doujin artist. Her doujin circle is called Beauty Love House, and Najimi uses the pseudonym Beauty Love when writing her doujinshi.

Her name is a pun on the Japanese term "Osananajimi" meaning "Childhood Friend."
