Bakuman - S1: Episode 20
Cooperation and Conditions
Mashiro and Takagi discuss how to improve the concept behind the story, now known as Detective Trap, and Takagi begins looking over many detective stories that Hattori sent him. The two meet with Hattori, insisting on proceeding with Detective Trap while still in high school, and Hattori tells them that in order to get serialized, Detective Trap must do well in the Golden Cup, and they must bring him a 19-page story every two weeks to show that they can do so every week with assistants. They succeed in keeping up in spite of the difficulty involved in doing so, and are officially entered into the contest.
