Doppo Kannonzaka/Story

Early Life

 * Since childhood, Doppo was mostly lonely and had no friends, apart from Hifumi Izanami. In high school, they both met Hobonobo Keitoin, however, Hifumi's experience with her resulted in developing a phobia of women. Several years later, Doppo and Hifumi started living together and Doppo was employed by the E.L. Medical Co., Ltd as a sales representative.


 * However, the work conditions at the company negatively affected Doppo's mental health, so he started to go to Jakurai Jinguji for counseling. Once, Doppo was taken to the Yokohama Police Station where he was interrogated by Jyuto Iruma.

Matenro

 * As Hifumi started working at a host club, he was targeted by one of his customers who desperately wanted Hifumi to love him and started stalking him. After she broke into their apartment and attacked Doppo (Hifumi saved him but took a hit himself), Doppo and Hifumi decided that they need to deal with it. Hifumi insisted that they need to help her, so Doppo took him to Jakurai. They explained to him their situation and asked him to use his Hypnosis Mic to heal her mind.


 * Although reluctant at first, Jakurai agreed to help them and thanks to Jakurai's friend's help, they found the stalker in the hotel in Shinjuku. While Jakurai and Hifumi went to confront her, Doppo being worried that something might happen, prepared the rescue mattress under the window, just in case. His worries turned out to be true, as both stalker and Hifumi fell out of the window but they survived thanks to Doppo.


 * After the stalker was hospitalized, Jakurai approached Doppo and Hifumi and gave them Hypnosis Mics, asking them to show him their skills. Doppo and Hifumi complied and Jakurai, being impressed by their skills, Jakurai offered them to form a team. Together, they formed Matenro to represent Shinjuku Division.

1st Division Rap Battle

 * Matenro were invited to participate in the Division Rap Battle, organized by the Party of Words. However, E.L. Medical Co suddenly received several requests from Dr. Shishikai, so Doppo had to work overtime. Jakurai, however, realized that Shishikai's requests were fraudulent and he wanted to separate Jakurai from his team, so Jakurai confronted him.


 * After winning the preliminaries, Matenro advanced to the main battle to face off Fling Posse, led by Jakurai's former teammate Ramuda Amemura. They arrived at Chuohku, where Doppo met Jyuto, although he didn't recognize him at first. Jakurai then got into a confrontation with Ramuda which was interrupted by Ichijiku Kadenokoji who used the Hypnosis Canceller. Doppo tried to explain to Ichijiku that Jakurai was merely defending himself, although Jakurai calmed him down and said that everything's fine.


 * Before the battle, Hifumi dragged Doppo to grab a drink together, however, they were approached by a group of fans who started chasing them. Doppo grabbed Hifumi and ran away, before they were joined by Gentaro Yumeno and Dice Arisugawa who were chased as well. Doppo apologized to Gentaro and Dice for the inconvenience. However, Hifumi suddenly started (although unintentionally) insulting Gentaro's clothing, resulting in Dice stepping in to defend his teammate. Doppo once again apologized for Hifumi's behavior, however, Dice told him that if he apologizes this much, his apologies are worthless, such as Doppo himself.


 * Hifumi, however, stepped in to defend his friend and challenged Gentaro and Dice for a rap battle. They were interrupted by fans, so Doppo and Hifumi had to run away again. Afterward, Doppo thanked Hifumi for defending him.


 * During the battle with Fling Posse, both Doppo and Hifumi were taken out, as well as Gentaro and Dice, leaving Jakurai against Ramuda. Jakurai defeated his former teammate, so Matenro advanced to the last battle against MAD TRIGGER CREW. During the battle, Hifumi was hit by MAD TRIGGER CREW, which made Doppo snap and unleash his rap ability, taking out both Jyuto and Rio, although Doppo was rendered neutralized himself. Jakurai confronted Samatoki Aohitsugi in a final clash and defeated him, making Matenro the champions.


 * As part of their victory, Matenro received the prize money and superiority over other divisions. However, while riding on the train, Doppo lost his share of the money, which made him upset. While celebrating their victory, Jakurai comforted Doppo and told them the story about his times with The Dirty Dawg.

Helping Asunaro

 * Matenro's victory positively affected Doppo's situation at the work, as more clients wanted to close deals with him, and even his boss became kinder to him. When he was returning home, he was approached by a kid named Asunaro Bojo who started badmouthing Doppo and demanding to bring her to Jakurai. Doppo was surprised by Asunaro's behavior but treated her to some food, after noticing that she was hungry.


 * Then, Hifumi arrived and started mocking Asunaro but then after Asunaro told them that she is a girl, Hifumi was terrified. Doppo stopped Asunaro for scaring Hifumi and together, they visited Jakurai. Asunaro explained that her brother was kidnapped by a group of criminals, and asked Matenro to help her, as she had no other option. Matenro agreed to rescue Asunaro's brother, so she brought them to the Yokohama container yard.


 * There, they were informed about a rap crew, hired by the kidnappers to protect them. Matenro entered the container yard and were suddenly approached by Buster Bros!!! who were also there. Matenro assumed that they were the ones working with kidnappers (meanwhile, Buster Bros!!! were thinking the same about Matenro) and confronted them. Doppo clashed with Jiro Yamada, however, their fight was interrupted by the Tobari brothers, the real kidnappers who used the Bojo siblings to lure Matenro and Buster Bros!!! into the trap.


 * All of them were too exhausted after the battle and couldn’t resist, so Tobari’s men succeeded. It was also revealed that the Tobari brothers were hired by Hitaki Tsumabira, the high-ranked Chuohku official who wanted to take down the teams for her amusement. However, she was stopped by Ichijiku who took her out for insubordination (as well as other crimes), leaving Tobaris behind. During the ruckus, Doppo was freed by Asunaro who apologized for helping Tobari, and Doppo told her that he'll save her brother.


 * While Bojo siblings went to free others, Doppo teamed up with Jiro to buy them some time and fight Tobari's men. Then, Matenro, Buster Bros!!!, MAD TRIGGER CREW, and Fling Posse joined forces to take down Tobari brothers and their men. The culprits were arrested, while Asunaro reunited with her brothers.

Clash with Bad Ass Temple

 * Doppo and Hifumi were invited by Jakurai for fishing at the local pond, although Doppo had next to no luck in catching anything other than a boot. Doppo, however, noticed that Jakurai was distracted by his thoughts and Hifumi said that if Jakurai needs their help he can count on them. Jakurai told Doppo and Hifumi about his former assistant Yotsutsuji Kannabi. He fell into a coma, seemingly because of Ramuda, which was one of the reasons behind the TDD disbanding.


 * Doppo assumed that Ramuda had no good reasons to betray their friendship with Jakurai and said that he could have no choice but to do that for one reason or another. He suggested that Jakurai and Ramuda need to talk about that properly and Hifumi even told Jakurai about his experience with Honobono and how he also intends to talk with her. Jakurai agreed with both of them that he and Ramuda need to talk.


 * Doppo was surprised that Hifumi wanted to face Honobono despite everything she did to him but Hifumi told him that he has to face his past sooner or later. Suddenly, Hifumi was informed that two individuals broke into the host club and started causing chaos, demanding for Hifumi to arrive. Hifumi then headed to the Fragrance to deal with them and Doppo joined in to help him.


 * At the club, Doppo and Hifumi were confronted by Kuko Harai and Jyushi Aimono, members of Bad Ass Temple. Kuko told them that they came to fight Matenro, the champions of the Division Rap Battle. Doppo and Hifumi realized that they have no choice but to fight, however, their battle was interrupted by the arrival of the police, as Jyushi suddenly grabbed Kuko and ran away, leaving both Doppo and Hifumi confused, although they couldn't help but notice the power of the Nagoya team.

E.L. Medical Scandal

 * Doppo was assigned by his company to work with Dr. Yamagushi from the Shinjuku Central Hospital to provide with him with the medical equipment. Yamagushi was satisfied with Doppo's work and commended him when talking to Jakurai what he also told Doppo about. However, his manager suddenly fired him because Yamagushi filed a complaint that the equipment provided by Doppo was malfuctioning. Since Doppo was the only one who worked with it, he was deemed a culprit, however, Doppo claimed that he didn't do anything.


 * With the help of his colleagues, Mitsuya and Ogura, Doppo investigated the incident and found out that the equipment had been swapped. Doppo met with Yamagushi and confronted him with the evidence, forcing him to confess that he was the one who swapped the equipment. As the situation was cleared up, Doppo was reinstated as the E.L. Medical employee, however, he confronted the manager for how he mishandled the situation and used Doppo as a scapegoat, as well as taking all the credit for his employees' work.


 * Suddenly, Doppo was contacted by Jakurai who informed him that Hifumi is in danger. Doppo rushed to the Fragrance where he saw that Hifumi was cornered by Honobono and jumped in to defend him. Doppo found out that Honobono was also the one responsible for Doppo being fired. As Hifumi was having an anxiety attack because of Honobono, Doppo attacked her, however, he wasn't able to land a hit on her, even when Hifumi stepped in to the battle to help Doppo. After Jakurai arrived and joined Doppo and Hifumi, she decided to retreat, so Doppo went to help Hifumi who was recovering from meeting with Honobono
