Najimi Osana just got fired from her job, and is looking for a new line of work. She accompanies her friend Tsuyuri to a Comiket event and helps her sell Tsuyuri's dōjinshi which primarily consists of rape manga. Najimi becomes curious about the dōjin world after she finds out how much money a popular dōjin creator can make, and even has runs into one such popular artist named Justice, who coincidentally is one of her childhood friends. Najimi proclaims that she will make her fortune through producing dōjin.

Tsuyuri gives advice on how to start drawing dōjinshi and recommends buying some "examples" in the form of an adult game. Tsuyuri takes Najimi to a video game shop, and gets her to buy a popular adult game, despite Najimi being extremely embarrassed at doing so. At home, Najimi attempts to play the game, but finds it too risky with her family there, so takes a ride on her bike to Tsuyuri's house. On the way, she is stopped by a policeman who wants to know what she is carrying, but Najimi runs off on her bike due to embarrassment. Eventually, she is surrounded by policeman and must open the bag the game was in, but it turned out the game had slipped out. The game is later returned to her by a man who saw her drop it, much to Najimi's despair.

Najimi finished her first dōjinshi she entitled "Love Typhoon" with plans to sell it at an upcoming event. However, when Tsuyuri reads it, she tries to turn away the subject by first commenting on the quality of the paper. Najimi attempts to sell her dōjinshi though finds it to be incredibly difficult. The guy she met earlier buys a copy, and Najimi is so overjoyed that she hugs him. Men nearby gather around and try to buy Najimi's dōjinshi to get a chance to be hugged as well, but retreat after Tsuyuri explains that they will not necessarily get hugged by Najimi if they buy the dōjinshi.

Tsuyuri had heard from Najimi earlier that she has recently started working at a part-time job, but Najimi would not tell Tsuyuri where she worked. This leads Tsuyuri to follow Najimi with Justice and Sōra to discover where she works. In the end, they find out much to Najimi's embarrassment that she works at a cosplay restaurant where the waitresses dress up like catgirls. Tsuyuri has a little fun with Najimi by asking her to write "Najimi is a dirty girl" with ketchup on the omlet she ordered. After Justice finds out the man who bought Najimi's first dōjin comes to the restaurant every day, he gets angry and protective of his childhood friend Najimi.

Justice is in despair after seeing Najimi go into a hotel with Junichirō, and thinking that they were going in there to have sex. Tsuyuri and Justice go to Najimi's apartment to help her with her dōjinshi, but in the process Tsuyuri does a play on words and likens their collaboration to having sex which makes Justice leave in an emotional outburst. Justice decides to make a five-hundred page dōjinshi in order to show Junichirō the error of his ways, even though Justice merely has the wrong idea about Junichirō and Najimi, who insists that there is nothing going on between them. Later at the comic festival, Najimi finds a rival who has about as much experience making dōjinshi as she does.
