When her agent urges her to participate in a gravure idol photo book, she struggles with the idea of showing her body to the public, but with Mashiro's support, she declines the offer. She and Mashiro communicate mainly through text messages and sometimes through phone calls, but rarely meet except by chance or under special circumstances.

Eiji Nizuma (新妻 エイジ) is a manga creator prodigy who won the Tezuka Award at age 15. He moves from Aomori to Tokyo to work on the serialization of his manga Crow on the condition that he gets the right to cancel any series in Weekly Shōnen Jump after becoming the magazine's most popular author. He later is drafted to illustrate Aiko Iwase's scripts in the form of +Natural, which he is able to effortlessly balance with Crow. After Crow enters its seventh year of serialization as one of Jump ' s flagship titles, Nizuma reveals that the series that he wants to cancel is his own, which he achieves after holding a record-breaking 20-week poll leadership, leading into the final chapter. From there, Nizuma decides to write a manga that would be "the number one in the world", and starts working on Zombie٭Gun with that intent. He enjoys being immersed in his work and blasting loud music in the background. He never seems to change his clothes, which consist of a sweater and sweatpants; he may not change clothes much, or has several similar outfits. Mashiro and Takagi declare him their rival, although he is very friendly upon meeting them and states he is a fan of theirs; indeed, this admiration also fuels their mutual rivalry and determination to write ever more enjoyable works. The head editor describes the difference between Mashiro and Takagi to Nizuma is their "love of manga"; indeed, Nizuma seems to have been obsessed with drawing manga since he was six years old. Nizuma tends to act conceited because he is hailed as a genius; however, after working on Crow for quite a long time, he becomes humbler, even claiming to "not be good enough of a manga artist to be judging other people's work" when asked by his editor to judge for the Treasure magazine. Nizuma is eccentric and has a variety of odd quirks, like constantly pronouncing sound effects while he draws and speaks, working to the sound of very loud music, and appearing most of the time with drawing quills tucked into the back of his shirt's collar, resembling small wings. Despite this, he has a keen eye for truly talented manga artists just by analyzing their work, and is a good judge of character. He works under the direction of the Weekly Shōnen Jump editor Yujiro Hattori and for a time with his two assistants, Shinta Fukuda and Takurō Nakai. His favorite manga is Doraemon.

Fukuda then gets serialized and is an aspiring rival to Ashirogi, Nizuma, and Nakai, going on to achieve considerable popularity with his following series, the motorcycle racing-themed Road Racer Giri. Among them, he is considered to have the worst drawings, though that they often border on grotesque apparently matches his stories. He can be extremely conceited, abrasive and competitive at times, yet helps out his rivals, who are also his friends.

 * Portrayed by: Hirofumi Arai (film), Yuu Fukuzawa (play)

Kazuya Hiramaru (平丸 一也) is introduced as a 26-year-old manga artist who quit his office job to draw manga after he picked up Shōnen Jump one day for the first time in his life and decided that drawing manga would be far less troublesome than office work. His first work, Otter No. 11 receives an honorable mention and becomes serialized around the same time as Mashiro and Takagi's work, though he has no experience or background knowledge with manga. Hiramaru is easily overwhelmed and finds it hard to deal with the stress of writing manga, having initially believed that being a manga artist would be an easy job. He sometimes hides in the other manga artists' studios. His editor manages to persuade him to continue by offering to help him get closer to Kō Aoki, as he is attracted to her; his attempts, however, usually end badly, but in chapter 114 he finally asks Aoki out. Due to his success, he has been called a manga genius possibly on the level of Eiji Nizuma, especially considering his inexperience and relative lack of interest in writing manga. His manga's successful stories stem from Kazuya's own negativity; if he becomes cheerier, his work suffers. Until near the end of the series Hiramaru's art was rather poor, which gave it votes from fans of comedy; however, Nakai (under Yoshida's orders) helped Hiramaru improve his drawing skills.

Aiko Iwase


Aiko Iwase (岩瀬 愛子) is a former classmate of Mashiro and Takagi's during junior high school, where she is known for scoring high on school rankings.

Takagi later turns her down after she states that she disapproves of his writing manga. She reappears as a student at To-Oh University along with Kō Aoki. Under the pen name Aiko Akina (秋名愛子), she writes her first novel while in University, which she expects will impress Takagi. However, Takagi's refusal to say that novels are better than manga angers Iwase, who decides to write a manga for Shōnen Jack to prove her superiority. Her editor is originally Hattori, who sees her talent and believes her rivalry with Takagi will be an excellent way to spur Ashirogi for their next series. However, she is frustrated that Takagi does not return her feelings even though he admits that she is more talented than Miyoshi. After Takagi marries Miyoshi, she transfers her feelings to Hattori, who finds the relationship uncomfortable enough to bring the issue to his captain. Miura is assigned as her editor, while Hattori reassigned to Ashirogi for their upcoming series; the change angers her, especially because she feels Miura is less skilled than Hattori. Her writing and plot are praised as very well made and she is the writer of +Natural. Her favorite manga is Adolf ni Tsugu.

Shoyo Takahama


Shoyo Takahama (高浜昇陽) is introduced as a 19-year-old rookie assistant for Ashirogi on Detective Trap.

He eventually gets his own series in Jump, Business Boy Kenichi with Nakai and Kato as his assistants and Gorō Miura as his editor. However, the series eventually gets cancelled. Without a series of his own, Takahama returns to being Muto Ashirogi's assistant for their next series Tanto, but eventually gets another series, Seigi no Mikata (Mikata's Justice), which winds up being very successful. Both Mashiro and Takagi think highly of him and value his opinion on manga, and Takahama often expresses his frustration towards Miura when the two groups share the same editor.

Ryu Shizuka
Ryu Shizuka (静河 流) is an 18-year-old newcomer manga artist who submits a manga called Shapon (The End of Japan) for an issue of Treasure. Nizuma considers him and his story to be second only to Mashiro and Takagi's manga in the same issue, stating that he was amazing and deep, and would have won if he had not been up against Muto Ashirogi. Because of the dark subject matter of his manga, he is working with a young editor named Yamahisa to make it more Jump-friendly. He has social anxiety disorder and is reluctant to talk to his editor face-to-face, instead preferring to have his meetings over the Internet. He is a recluse who has spent much of his time in his room with video games and computer since the eighth grade and is sensitive to the words of others. He starts to become more comfortable talking with Yamahisa further on in the story and Yamahisa later helps him buy his own apartment and begin conversing with people. Ryu's work eventually becomes much more lighter; he is last seen saying his next work will be one focusing on hope. His favorite manga is Level E.

Shun Shiratori


Shun Shiratori (白鳥 シュン) is one of Ashirogi's assistants when Perfect Crime Party begins publication. He comes from a very wealthy family and is somewhat sheltered, so he does not know basic things like how to run a washing machine.

After meeting Ashirogi and their other assistants, Shiratori is encouraged to pursue his dream to become a manga artist and creates his own series, Rabuta and Peace, based on himself and his dog, Peace, with some initial help from Takagi. Thanks to the Ashirogi team and his older sister Hitomi, Shiratori stands up to his mother, who reluctantly allows Shiratori to live on his own and follow his own path.

Toru Nanamine


Toru Nanamine (七峰 透) is a manga artist who was inspired by the early works of Muto Ashirogi and attempts to surpass them. He is however also highly distrustful of the editor-author relationship and creates a scheme to undermine it. While Nanamine initially appears as an extremely enthusiastic individual, he is actually sly and supremely arrogant, believing that no opinion other than his own matters and angrily lashing out when his assertions do not hold true. In particular, he believes the more reader opinions one can obtain beforehand, and the more suggestions can be incorporated into the manga, the better the manga will be. As a result, he uses unscrupulous means and regards his editor, Kosugi, with great contempt. Though Nanamine is a skillful artist, the means he uses to construct his story result in an increasingly fractured plot and he is eventually forced to concede to the stronger Ashirogi team when his dwindling pool of online advisors abandon him after learning how he lied to them. He later returns using an even less ethical method of using paid advisors to create the perfect manga for himself, initially testing the system with veteran manga creators and abandoning them. The act outrages the majority of manga creators and editors; the editor in chief only allows Nanamine to submit his work when Ashirogi and other artists express the desire to defeat him in direct competition. However, Nanamine fails to obtain one of the top three spots in the rankings and is banned from Shōnen Jump, as stipulated by the editor in chief; ironically, the third spot that got Nanamine out of the rankings is taken by a one-shot from Mikihiko Azuma, one of the washed-out manga artist employed and later discarded by his latter scheme.

Naoto Ogawa

While he is careful to balance his work and family life, Ogawa sincerely cares about the quality of his employer's work. After "Trap" ends, he does not return until Ashirogi decides to hire a fourth assistant for the serialization of Reversi, during which he helped Mashiro manage deadlines and brought in two extra assistants when the Ashirogi team fell behind attempting to complete three storyboards simultaneously.

Natsumi Kato


Natsumi Kato (加藤奈津実) is a bespectacled assistant who works for Ashirogi during the serialization of Detective Trap. She has worked a year in shonen and a year in shojo. She develops a crush on Mashiro, but gives up after meeting Azuki during Mashiro's hospitalization. After "Trap" is canceled, she becomes Takahama's assistant on Business Boy Kenichi, where she forms a friendly relationship with Nakai, until he misconstrues her amiability as romantic. She later assists Aoki on Time of Greenery, and returns to assist Ashirogi when Shun Shiratori resigns to work on his own manga series. She is friends with rookie voice actress Ririka Kitami, who is more oblivious and emotional than Kato; she often has to correct or pacify Ririka when she's thinking about something. Her favorite manga is said to be either The Rose of Versailles or Glass Mask.

Ichiriki Orihara


Ichiriki Orihara (折原一力) is introduced as Ashirogi's new assistant during their serialization of ''Vroom! Tanto Daihatsu''.

After Takagi and Mashiro choose to end "Tanto," he agrees to work for them without pay and taking non-assistant work as a part-time job until they got a new series. Orihara remains Ashirogi's assistant during Perfect Crime Party and Reversi. Like Eiji Nizuma, Orihara is a bottomless pit, able to eat large amounts of food without suffering a stomach-ache. He also reads Tozai Sports; coincidentally, it was because of this that he was to show Mashiro and Takagi the negative take the newspaper did on the relationship between Miho and Mashiro. His favorite manga is Slam Dunk.

Shuichi Moriya


Shūichi Moriya (森屋秀一) is one of Ashirogi's assistants for Perfect Crime Party and Reversi. 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, which he regards as an art form that deserves more respect. While he is also an aspiring manga artist with excellent drawing skills, editors have remarked that his works tend to lecture at audiences and need to be simplified. Though he did not get along with Shiratori at first because Shiratori considered manga a commercialized product, they manage to reconcile their views thanks to Mashiro. As an assistant, he is dedicated and supportive; although he dislikes Ogawa for becoming Ashirogi's head assistant during Reversi because Ogawa will leave while the other assistants stayed behind, he comes to respect Ogawa when he returns at a critical hour with two additional assistants to help meet an important deadline. One of Moriya's favorite manga appears to be Osamu Tezuka's Phoenix.

After The Perfect Crime Party is serialized, Hattori returns as Muto Ashirogi's editor, leading Miura to edit Iwase's work. He is somewhat of a schemer and likes to plot both behind other editors and even his own manga artists to advance the interests of the magazine. As such he came up with the idea of having Nizuma and Iwase collaborate on +Natural in order to inspire Mashiro and Takagi to work harder. His favorite manga is Cobra.

Goro Miura


Goro Miura (港浦 吾郎) is Mashiro and Takagi's editor between the start of Detective Trap and the serialization of Perfect Crime Party. Initially he is very enthusiastic but naive and somewhat incompetent due to lack of experience. He is desperate to get one of his series serialized in order to protect his job, and believes that gag manga have a better chance of doing so. This often clashes with Mashiro and Takagi's approach, leading to some arguments. Over time, and through the tutelage of Hattori, he becomes more flexible and his personal desires do not come into play as often, and Ashirogi come to accept him as an editor. He is also the editor for Takahama's Business Boy Kenichi and Seigi no Mikata and eventually becomes Iwase's editor. His favorite manga is Jungle King Tar-chan.

Hisashi Sasaki (佐々木尚) is the editor-in-chief of Weekly Shōnen Jump. Earlier in his career he had worked with Moritaka's uncle Nobuhiro as his editor. He eventually had to break the news that Nobuhiro would have to leave Shōnen Jump, leading to his unemployment and eventual death. Despite his stoic and stern demeanor, he is very passionate about what he does. Sasaki also likes to delegate responsibilities when able in order to give his subordinates experience. When dealing with the manga artists, he does not hesitate to put them in their place and will resort to trickery, much like Hattori, to make them see what will happen. Sasaki later becomes the editor in chief of the fictional new monthly magazine, Hisshou Jump. The character is based on the real person of the same name who was the editor-in-chief of Weekly Shōnen Jump from 2008 to 2011, coinciding with the majority of Bakuman's serialization.

Yoshihisa Heishi


Yoshihisa Heishi (瓶子吉久) is the Deputy Chief Editor of Weekly Shōnen Jump. He has a serious personality and usually follows Sasaki's orders but does appear to have his own reservations sometimes.

Yujiro has difficulty keeping Eiji in line, but prides himself on finding such a talented manga artist. Because he shares the same last name as Akira, he is referred to by his first name while Akira as referred to as "Hattori". He finds it difficult to get along with Nizuma and Fukuda at first due to their eccentric or brash personalities, but soon becomes accustomed to them. 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


Koji Yoshida (吉田 幸司) 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 do not seem to work after Hiramaru is engaged to Aoki, Yoshida's lies seem sufficient to manipulate Nakai into assisting Hiramaru.

The real Koji later said he was not happy about a character in the series sharing his name.

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.

Tatsurou Kosugi


Tatsurou Kosugi (小杉 達郎) is the editor of Toru Nanamine and the newest member of Jump's Editorial Department. Due to his inexperience and subservient personality he is an easy prey for Nanamine to exploit at first, but learns to become more assertive over time. He believes that his lack of experience is partially responsible Nanamine's disrespect towards the editorial department. Though Nanamine never shows any respect or any intent to listen to Kosugi's suggestions, Kosugi never wavers in his attempts to help Nanamine and expresses some remorse that Jump has lost a talented artist after Nanamine's final scheme fails and he is given a lifetime ban from Jump. At the end of the series, Kosugi is assigned to become the editor of Iwase and deal with her forceful personality much like Miura had before.
