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)
Age: 14 (debut), 24 (end) Birthdate: November 5, 1993 Blood Type: B Height: 162cm Weight: 44kg Azuki is Mashiro's classmate. Her dream is to be a voice actor. She agreed to marry Mashiro when both of their dreams come true. However, she also told him that in the mean time, they should not have any distractions so they will contact each other only through emails. Her best friend is Kaya Miyoshi. Although her outer image is shy, she is a very mysterious girl. It is sometimes hard to know what she is thinking about. After securing her role as the main heroine in Ashirogi Muto's "Reversi," she finally receives a proper marriage proposal from Mashiro, which she accepts. They begin living in her old house which Mashiro purchased and are married following Ashirogi Muto's next serialization.
Age: 40 (currently) Birthday: June 23, 1978 Yoshida is Hiramaru Kazuya's editor. He tells the chief-editor in the meeting about his genius, which led to Hiramaru's serialization. He is able to ignore Hiramaru's personality. He is also a Captain, meaning he gets to sit in the serialization meetings and lead the other editors in his team, like Yamahisa. Yoshida is perhaps the most manipulative of the editors shown. When he realizes that forcing Hiramaru to work isn't applicable to an efficient and/or long-running series, he bribes him with rich items or information about Aoki Ko in order to get him back to work and pay off the debts he owes for buying such items. Yoshida is able to keep this running for an extended period of time (throughout the 200 chapters of Otters 11), even threatening Hiramaru with disassociation with Shueisha if he does not get serialized again after Otters 11 gets canceled. Yoshida's reason and rationality are even more key to his character. He is able to deduce that Niizuma Eiji was responsible for +Natural's artwork and worries that Hiramaru's manga will take a dive if he asks Aoki Ko out and gets rejected, knowing that Hiramaru most probably will get rejected. This reasoning has its limits, however, as Yoshida was greatly surprised that Aoki accepted Hiramaru's proposal, though it would later scratch away most of Hiramaru's negativity and cause a dive in his manga quality.
Age: 19 Orihara is a young assistant who worked with Ashirogi Muto on "Run, Daihatsu Tanto!". He is a very energetic and cheerful character that tends to get loud due to his excitement, may it be about work or something else. When Takagi and Moritaka decide to quit the series, he offers to keep working for them without payment, because he still wants to learn from them. He works as an assistant again, when they start publishing "Perfect Crime Party".
Age: 18 (debut) Shiratori Shun is an assistant for Ashirogi Muto's Perfect Crime Party and the mangaka of Rabuta & Peace. Shiratori comes from a wealthy family and has a sister. He applied to be Eiji Nizuma's assistant, but the editors had already filled that position, so he was instead hired as Ashirogi Muto's assistant. He was rejected from art school and didn't think he would make a good mangaka, but when he saw an advertisement to be an assistant he took the chance, not wanting to mooch off his parents anymore. Shiratori is a happy boy with simple emotions who easily blushes. He speaks what he feels. He loves art and feels that it should be seen and enjoyed by thousands of people. That is why he draws manga as opposed to his grandfather, who purchased art and kept it in his house where people rarely saw it. (Source: Bakuman Wikia)
