"Dojin Work" centers around Najimi Osana, a high school girl who stumbles into the world of creating and selling doujinshi, or self-published works, after a chance encounter with her classmate Tsuyoshi. Initially, Najimi is unaware of the concept of doujinshi, but Tsuyoshi introduces her to the subculture, sparking her curiosity. Despite her lack of artistic talent, Najimi decides to create her own doujinshi, driven by the potential to earn money and the allure of the creative process.

The series follows Najimi as she navigates the challenges of producing her first doujinshi, from brainstorming ideas to dealing with the technical aspects of printing and distribution. Along the way, she encounters various characters who are deeply involved in the doujinshi scene, including her friend Kousaka, who becomes her partner in the endeavor. Kousaka, a talented artist, complements Najimi’s enthusiasm with her skills, though their collaboration is often fraught with comedic misunderstandings and mishaps.

As Najimi delves deeper into the world of doujinshi, she attends conventions, interacts with other creators, and learns about the competitive and often chaotic nature of the industry. The series highlights the dedication and passion required to succeed in this niche field, as well as the camaraderie and rivalries that develop among creators.
