Due to his success, he later becomes a team leader and matures as an editor as he learns to take into consideration the factors that allow manga creators and their editors need to succeed. Koji Yoshida is an editor team-leader at Shōnen Jump and the editor of Hiramaru. A perceptive and astute editor, Yoshida's editing style is unscrupulous and he will use any means to get his authors to work. In Hiramaru's case he uses bait in various forms, lies about this bait, and exploits of Hiramaru's interest in Aoki. He also tricks Hiramaru in buying an expensive car and renting an expensive apartment to keep him from saving up money and forcing him to continue to work. When interacting with Hiramaru, Yoshida's face is usually not visible for the reader, though Yoshida appears in full in the editing department, as a reflection of their antagonistic relationship. His ability to manipulate Hiramaru lessens over time, particularly when Hiramaru makes it apparent he is aware of Yoshida's machinations when he complains that Yoshida needs to be more effective, though Hiramaru comes to trust that Yoshida does seem to want what is best for him. Though his manipulations don't seem to work after Hiramaru is engaged to Aoki, Yoshida's lies seem sufficient to manipulate Nakai into assisting Hiramaru. Masakazu Yamahisa is the editor behind Aoki's Time of Green Leaves and the editor of Ryu Shizuka. Yamahisa is a smooth-talker and attempts to garner the trust of his manga artist by reading their emotions. He personally decides to become Aoki's editor, seeing her marketability as a female manga artist, and helps her achieve success as a manga artist in Shōnen Jump by playing to her strengths in writing romantic or fantasy stories. As Shizuka's editor, Yamahisa seems genuinely concerned for Shizuka because of his lack of social skills, taking it upon himself to civilize him to the point of taking him out to hostess bars (which was one of many options he listed). While some of Yamahisa's attempt to help Shizuka backfire, they ultimate contribute to Shizuka's ability to create an interesting manga series and allow Shizuka's confidence grow. By the end of the series, Yamahisa is shocked to see how cheerful Shizuka has become from his times out of his apartment; before this, he often had to track him down when he was not making manga like he was supposed to.
