Age: 26 (debut), 34 (end) Birthday: June 18, 1984 Birthplace: Kanagawa-ken, Japan Hiramaru was a salary man that hated working. On hearing Takagi and Mashiro talking about drawing manga on the subway and finding an abandoned copy of Jack, he quit his job to be a mangaka because he thought it would be less work for him. He is a different kind of genius compared to Eiji because he is talented even though he just started to write manga more in of a spur of the moment. After teaching himself to draw manga in a very short amount of time, his manga, Otters 11 is serialized. He is hailed as a genius by Koji Yoshida who pushed for his serialization saying that Hiramaru had no real motivation to continue as a mangaka and failure would just make him quit. Hiramaru is extremely lazy and immediately regrets getting serialized due to the amount of work to keep up a weekly series. He has said that he doesn't know why people have to work for a living and that he wants to sleep when he's tired and to eat when he's hungry. Due to his laziness, his editor, Koji Yoshida, often schemes to manipulate Hiramaru into working. Hiramura often tries to escape Yoshida to avoid working. His attempts to escape Yoshida is a long-running gag in the manga. He is also a chronic hypochondriac and often makes incredible claims of illness. However, he is always proven healthy by the doctors. It's mostly believed that his "illnesses" are not only a product of his own fears, but also serves as an excuse to avoid work. Hiramaru has a huge crush on Aoki Yuriko. Yoshida bribes him into doing work by giving him weekly facts about Aoki. Yoshida also often depicts dramatic scenarios of Aoki rejecting him due to his laziness or inability to produce names to energize him to work hard. Because he can't stand the idea of losing Aoki in his life, a combination of his own anxiety and Hiramaru's end-game scenarios, he works feverishly in hopes his work will earn Aoki's heart. Eventually, he gets engaged to her in Chapter 160.
Age: 15 (debut), 26 (end) Birthdate: November 3, 1992 Eiji Nizuma is a high school genius mangaka who has been drawing ever since he was young. Moritaka Mashiro and Akito Takagi consider him their rival. He was supposed to serialize a manga called Yellow Hit but he wanted to draw a different manga, Crow, which appeared in Akamaru Jump instead. His assisants were initially Nakai and Fukuda (Mashiro also worked for him temporarily before Detective Trap was serialized). His editor is Hattori Yujiro. He once demanded to be allowed to end one series he hated if he ever made it as the most popular author in Jump. Niizuma is slightly naive, but can also be serious and calculating when he wants to. Eiji tends to act conceited because he is hailed as a genius; however, after working on Crow for quite a long time, he grew more humble, even claiming to not be "good enough of a Mangaka to be judging other people's work" when asked by his editor to judge for the Golden Future Cup. (He judges anyway, but is not very helpful, only expressing his interest in Ashirogi and Ryu Shizuka). He tends to make noises and sound effects when drawing or writing his manga. Eiji is constantly chastised by his editor, and at first seems to be rather oblivious toward his rivals' feelings toward him, even expressing great excitement when he meets Ashirogi Muto and saying he is their fan. He is a great lover of manga and his opinion are valued by everyone at Jump, including his rivals. He refers to himself as an "Eternal Boy" and that is why he writes Shonen manga. He has only ever had a crush on one girl, back in elementary school, which paired with his naïveté most likely explains his lack of success in the Super Leaders' Love Fest.
Age: 24 (currently) Birthday: June 9, 1994 He is an assistant to Ashirogi Muto when they publish Perfect Crime Party. He is a year younger than Mashiro and Takagi. After he became a finalist in the Tezuka Award he decided to drop out of design school and concentrate on manga. Moriya seems polite but it is revealed in his thoughts he has a very negative view on others. He can be quite snippy at times. Moriya believes manga should be about the art and creativity, and you shouldn't worry about popularity because you won't get anywhere if you do. (Source: Bakuman Wikia)

She wants Mashiro and Takagi to be successful mangaka. Haruno looks very young despite her age and wears her hair in ringlets. She bears a strong resemblance to her eldest daughter, Miho, especially when Haruno was younger, looking almost exactly like Miho. (Source: Bakuman Wikia)
Age: 19 (debut) Takahama was one of Ashirogi Muto's assistants, along with Ogawa and Kato, for Detective Trap. He did the figures, both sketches, and inks. Miura said he was the best artist of the new assistants he was in charge of. Originally, Takahama seemed very unsocial and didn't talk much at all. However, after coming to respect Mashiro's work ethic as a mangaka, he reveals his ambition to work at Disney and spends several nights discussing manga with Mashiro and Takagi. He seems to be very enthusiastic about his manga, and grows frustrated with Miura after he feels that he is not letting him make the manga he wants. He respects people for their ambition and work ethic, as shown when he states that he has little in common with Ogawa and Kato because they are just happy with being assistants. Later on, he get his own manga, "Business Boy Kenichi" (Seigi no Mikata), which centers around solving legal cases. He eventually makes his way to the single-digit rankings, garnering only a few votes below or above of Ashirogi Muto several times over the course of his manga career and becoming a major character in the series. Eventually, he, too, joins Team Fukuda. When Niizuma announced his intentions to end Crow, Takahama is among the mangaka to oppose him. Takahama tries to prevent Niizuma from ending Crow by writing a captivating court case in his manga where a close friend of the main character is placed under false charges and the main character must prove his innocence. Takahama only manages to land second place, however, but expresses optimism at getting second place for the first time. (Source: Bakuman Wikia)
