Age: 18 (debut) Nanamine Tooru is a newcomer mangaka. He has been a fan of Ashirogi Muto since their early days, even going so far as to sending them fan letters periodically, voicing his opinions on their various manga. He seems cheerful, sociable, and easy to talk to. Nanamine is initially introduced as a cheerful, overly talkative person. However, his bubbly personality is revealed to be just a facade. He is actually a calculative and extremely manipulative individual as shown in Chapter 118, primarily using several other people gathered online to help him edit his manga instead of his editor Kosugi. Nanamine additionally lies to his online chat friends about his manga's rankings in order to boost their morale. However, Nanamine's manipulation and confidence of such makes him overconfident of his abilities (and those of his online editors). Such is seen when both Yoshida and Niizuma Eiji, analytical manga editor and mangaka respectively, read his manga independently, and both state that the manga does not reveal his personality and that he's effectively superimposing mainstream lines onto his manga to make it popular. Nanamine persists in his arrogant methods, but only due to the pressure his estranged businessman father puts on him to become the best. He is revealed to have taken a large amount of money from his father and started his own company, where he pays high school students to read manga and come up with ideas for veteran authors to follow. Nanamine has been a huge fan of Ashirogi since junior high. He consistently sent fan letters to his favorite mangaka throughout the course of their work since "Detective Trap." He emulates Ashirogi in his story by using similar themes and motifs as the ones used in their earlier work. He submits a story called "Classroom of Truth" for the Treasure award when Ashirogi is judging. The story is dark and cynical in a similar fashion to Ryu Shizuka's "True Human," and is interesting enough for some pages to be shown full-scale in the Bakuman manga. Due to its incredible deviation from mainstream manga, however, and despite its clear-cut superiority over the other manga submitted for the award, it does not win. Though he is only eighteen, his manga is possibly better than both Shizuka's and Ashirogi's, and he is hailed as a genius by JUMP's editorial department and requested for a lighter version of the Classroom of Truth. Right after his first meeting with Kosugi, he uploads the "Classroom of Truth" online, causing the editorial department a frenzy that bombards them with protests of the means they use to edit their stories. He eventually deletes the blog at Kosugi's request, but his manga still remains online by people who've made copies of it. Upon visiting Ashirogi, Nanamine reveals his true colors to the pair, causing both of them to react with disapproval. Disappointed by the disagreement of the authors he idolized, Nanamine challenges them to a managaka popularity contest, each group using their respective methods. His one-shot "The Thing That Comes with Being Nervous" is made drastically more real as opposed to his editor's requests for him to tone it down and make it slightly more comical. It takes the top spot in the issue it is presented in. Nanamine then works to get a serialized version of an alternative version of "Classroom of Truth" to the magazine, called "What is Required for a Good School Life." Meeting with Kosugi, Nanamine lets slip that he has been consulting fifty others from online to improve his manga, with editors and former editors among them. He effectively ransoms Kosugi with Jump's declining popularity and Kosugi's decreased reputation should Kosugi refuse to agree and become "number fifty-one." When Kosugi mentions that Nanamine's backgrounds are relatively low quality to Ashirogi Muto, Nanamine reveals that he has hired Nakai as his Chief Assistant. Nanamine frequently lends pizza money to the obese man and reveals to Nakai that he was working with others to come up with ideas for manga. Most notable, however, is that Nanamine expressed fury that he was second to Aoki Ko's What God Gave Me, and stated that his manga was too high a caliber for the readers to understand, refusing to listen to Kosugi's opinion in the matter. After tearing up the early results sheet, he went online and told his 50 editors that it had taken the first place spot. While Nakai's art does sustain What is Required's second place in the second chapter, the resulting chapters drop their place dramatically, and over half of Nanamine's cowriters leave the chatroom when Nanamine proves stubborn and starts to cut out some of their ideas. Nanamine's drop to fifteenth even causes him to call Takagi in hopes that they would write the same story and compete with only artwork. Though Takagi initially rejects the deal, Kosugi's worry over Nanamine's mental state causes him to allow the deal to be made, and the two chapters compete with the same story. This deals an even greater blow to Nanamine, as while people who voted for PCP also tended to vote for What is Required, the effect of copying the story cost Nanamine everybody who also voted for PCP. Nanamine considers quitting, only to be repeatedly punched by Kosugi, who refuses to allow Nanamine to quit and advises him to write a more Shonen plot, which Nanamine seems to be able to do. Nanamine is next seen at the New Year's Party with new resolve, telling Ashirogi that he will defeat them with another method. Ashirogi welcomes his challenge and Nanamine leaves the party to work on a new series. What is Required is revealed to be cancelled in later chapters. It is revealed that Nanamine was behind Mikihiko Azuma's submission of Panty-Flash Fight, having previously discussed the matter of his success with his father. Four floors of a building was rented out and his old methods are put into play to fuel the stories of veteran authors who've lost touch with their readers. Several of these veteran authors immediately go to JUMP to publish their stories, much to the chagrin of several authors and editors, who believe that younger authors now have less of a chance to publish their manga. In this operation, he hired Kyoichi Murasaki as his second-in-command. When Mashiro and Takagi are invited to Nanamine's company to observe his methods of creating manga, Nanamine demonstrates his significant improvement in the system, but fails to win the approval of his favorite mangaka. Later on, Nanamine abandons the veteran authors, inciting the fury of the members of Team Fukuda, who express their anger and determination to their editors about crushing Nanamine's new series. Nanamine is then contacted by Editor-in-Chief Sasaki, who expresses his disapproval of Nanamine's abandonment of the veteran authors and challenges Nanamine to get in the top three with a one shot, lest he be banned from writing for JUMP. Despite getting a good score from his company's reviewers and due to shooting down Kosugi's suggestion to make his one-shot more shonen, Nanamine only manages to get fourth. Especially upset at having lost to Mikihiko Azuma, who was among the veteran authors he left, Nanamine tears apart the PCP poster on his wall and angrily tells Kosugi to leave his presence.
