Jyuto Iruma/Story

Police Force

 * After losing his parents in a car crush, involving a drug addicted driver, Jyuto swore to eradicate the drug traffic by all means and joined the Yokohama Police Department. There, he was approached by a senior officer who took Jyuto under his wing and became his close friend, teaching him how to be a cop. However, he became addicted as well and died from an overdose, prompting Jyuto to start and all out war on drugs. In the pursuit of his dreams, however, Jyuto realized that the justice system is not only his weapon in his war but also an obstacle, which made him use illegal means.


 * Jyuto was dispatched to the Ikebukuto Sunset Building to deal with the terrorist attack, perparated by Mozuku Shito. He noticed Samatoki Aohitsugi and Ichiro Yamada desperately trying to get on the crime scene and thought of that as an opportunity. Jyuto offered Samatoki a deal: he will let them to enter the building and confront Mozuku but in exchange, Samatoki had to testify and give all the credit for the success of the operation to Jyuto, which Samatoki accepted. Samatoki did his part and Jyuto rose through the police ranks, which helped him a lot in his war.


 * Jyuto was tasked to interrogate Doppo Kannonzaka after he was brought to the police station for unknown reasons. After the government was overthrown by the Party of Words, Jyuto became a direct subordinate of the Party and Ichijiku Kadenokoji herself.

MAD TRIGGER CREW

 * As the police was informed about the large drug transaction and decided to bust it himself, without waiting for the reinforcement, due to the big amount of product involved. However, Jyuto was captured, and as he refused to obey him, the dealer ordered his men to kill Jyuto. Thankfully, Samatoki who also was after the dealers intervened and saved Jyuto, so together they took the dealers down. Jyuto thanked him and Samatoki saw the potential in Jyuto and offered him to form a team together, as he promised to help Jyuto to make his dream come true.


 * Jyuto accepted the offer and built a mutually beneficial relationships with the Katengumi yakuza clan, although he had to make sure that Taiko Katen, the boss of the clan won't intervene in their business. As the Division Rap Battle was close, Jyuto procceded to search for the third member and met Rio Mason Busujima while working on the case. Jyuto decided that Rio would be a perfect addition to their team and ask Rio to meet Samatoki.


 * Jyuto went to the police station to liberate Samatoki from the cell, as he was arrested after a confrontation wiht the Tobari brothers (he had to blackmail his colleague to make him sign the papers). Jyuto then drove Samatoki to Rio's campsite in the forest, although Samatoki wasn't enthusiastic about recruiting the third member. Jyuto, however, reminded him that they need a team of three to participate in the Division Rap Battle, so he could fight Ichiro.


 * However, upon arriving to the campsite, Samatoki and Rio were hostile towards each other and clashed in a rap battle. Jyuto then noticed that they were surrounded by a group of criminals who were after Rio's Hypnosis Mic. Jyuto, Samatoki and Rio joined forces and took down the criminals. While Jyuto was contacting the police for reinforcement to apprehend the criminals, Rio accepted Samatoki's offer and joined their team. Rio also treated both Samatoki and Jyuto to his cooking, and although Jyuto was terrified by it he ate it all.


 * During the meeting, Rio told Jyuto and Samatoki about the situation with his former unit and the commander that was arrested by the Party of Words. MAD TRIGGER CREW then participated in the preliminaries for the battle and although they won, Rio was too distracted and couldn't keep up. Although Rio said that he was okay, Jyuto and Samatoki followed him and found out that his former squadmates led by Kubiki planned to attack Chuohku and liberate the commander. Rio confronted them, as Jyuto and Samatoki helped him defeated Kubiki and his men.

First Division Rap Battle

 * Prior to the Division Battle, MAD TRIGGER CREW arrived at Chuohku where Samatoki reunited with his ex-The Dirty Dawg teammates. Jyuto also met Doppo there and chatted with him a bit, although Doppo didn't recognize him at first.


 * Samatoki got into a confrontation with Ichiro, so Jyuto had to intervene to stop Samatoki, as his reckless actions could get them in trouble. Despite his efforts, Samatoki clashed with Ichiro, however the battle was stopped by Ichijiku who used the Hypnosis Canceller. Jyuto reported to Ichijiku and apologized for the incident, as Ichijiku turned the blind eye due to the upcoming battles but told him that it won't happen again.


 * Before the battle, Jyuto was approached by Rio who wanted to treat him and Samatoki to his cooking but Jyuto told him that he will treat him instead, as he couldn't take more of Rio's cooking. At the restaurant, however, they approached Jiro Yamada and Saburo Yamada who were quite hostile towards them. Jyuto noticed Saburo's anxiety and teased him, prompting Jiro to jump in and defend his brother.


 * Jiro challenged both Jyuto and Rio for a battle, however, he couldn't land a hit on them, as Jyuto and Rio mercilessly attack him. Before they could finish him, Saburo joined Jiro and together they managed to fight back. Jyuto then ceased the battle, noticing that it could get them in the unfortunate position and discussed with Rio that Jiro and Saburo might pose a threat.


 * During the battle between Buster Bros!!! and MAD TRIGGER CREW, Jiro and Saburo were defeated and Jyuto and Rio were taken out by Ichiro, however, Samatoki defeated him, so MTC secured the victory. At the final battle against Matenro, Doppo used his Rap Ability to take out Jyuto and Rio, while Jakurai managed to defeat Samatoki, leaving Matenro as the champions. After the battle, Samatoki thanked Jyuto and Rio for sticking with him and said that the next victory will be theirs.

Grasshopper Traffic

 * The police department received an information about the traffic of the Grasshopper drug in Yokohama, and Jyuto was put in charge of the task force to take it down. After busting some local dealers, Jyuto was informed of the large transaction at the container yard, so he joined forces with Samatoki who was also tasked to chase the dealers out of the Katengumi's turf. They approached Rio and asked him for the help, as Jyuto also told him about his war on drugs. Rio agreed to help them and they planned the attack, but not before Rio treated them to his cooking again.


 * At the container yard, MAD TRIGGER CREW suddenly bumped into Fling Posse who were carrying suspicious bags. Jyuto tried to force Dice Arisugawa to show him the contents of his bag, however, Gentaro Yumeno intervened, refusing to tell Jyuto what they were doing there. Jyuto assumed that Fling Posse were involved in the drug deal and MAD TRIGGER CREW confronted them, as Jyuto attacked Gentaro.


 * However, the battle was stopped when Zannen Tobari used the Canceller to neutralize him. Zannen revealed that spreading the drug in Yokohama was part of his plan to lure MTC and other teams into his trap, and then ordered his subordinates to restrain Jyuto and the others.


 * All of them were too exhausted after the battle and couldn’t resist, so Tobari’s men succeeded. It was also revealed that Tobari brothers were hired by Hitaki Tsumabira, the high-ranked Chuohku official. Jyuto tried to ask Hitaki why she involved herself in this, as her hatred towards men made her want to see teams being torn down for her amusement. However, she was stopped by Ichijiku who took her out for insubordination (as well as other crimes), leaving Tobaris behind.


 * With the help of Bojo siblings, all four teams managed to free themselves and joined their forces to take down Tobari brothers and their men. As the police proceeded to dispose of the Grasshopper and take Tobaris into custody, Jyuto concluded that the traffic will stop for now. Rio also noticed that Samatoki and Jyuto were hungry, so he decided to treat them to the balut he cooked, much to Jyuto's horror.

Chuohku Intervention

 * One day, the police received an emergence call from Chuohku, as the group of the Party's officials led by Nemu Aohitsugi ordered Jyuto to bring them to Samatoki, so they could arrest him. Jyuto had no choice but to oblige and brought them to the Katengumi's HQ, although he attempted to warn Samatoki and tell him to run away. Nemu approached Samatoki and ordered her subordinates to apprehend him for the violation of the Hypnosis Mic usage (Samatoki used the mic against an unarmed robber).


 * Jyuto was not in the position to stop her, however Rio confronted Nemu, pointing out that her case is flawed. Rio then pressured Jyuto and he spoke to Nemu, mentioning that what she did is an abuse of power and she must let Samatoki go. Nemu took it as the insubordination and threatened to report Jyuto, but he didn't care and prepare to fight Nemu if needed. However, Samatoki asked them to leave him, as he completely gave up after his own sister told him that she doesn't need him. Jyuto didn't take it well and together with Rio, they inspired Samatoki to fight back.


 * MAD TRIGGER CREW confronted the Party of Words, as Jyuto and Rio managed to take out Nemu's subordiantes, while Samatoki fought Nemu herself. Suddenly, Nemu was contacted by Ichijiku who ordered her to withdraw, as she never gave her a permission to arrest Samatoki. Nemu had no choice but to leave and Samatoki thanked Jyuto and Rio for helping him out.

Intercepting a Drug Deal

 * Jyuto's department received an information about Utashiro and rogue members of the Katen family being involved in the drug trafficking, so MAD TRIGGER CREW set up an ambush at the port to intercept them. After Rio blocked their way out, Utashiro and his men confronted MAD TRIGGER CREW only to be defeated. Jyuto then contacted the police for reinforcement so they could apprehend the criminals. However, Rio noticed that Jyuto and Samatoki were hungry and said that he will treat them to his cooking, to their horror.


 * When Samatoki was contacted by Jakurai who needed help in finding any clues regarding Doppo's case, Samatoki called Jyuto asking him for help. Jyuto used his contact at the department and sent Matenro images from surveilance system where they managed to identify Ginda Uwabimi.

Yakuza Turf War

 * During the turf war between Katengumi and Binzuigumi yakuza clans, Binzuigumi set up a drug deal at the underground casino in Yokohama. Jyuto informed Samatoki and Rio about their plans, so they decided to infiltrate the casino in disguise to strike down the Binzuigumi members. After a brief encounter with Dice, MAD TRIGGER CREW spotted the criminals and chased them only to find out it was a trap. Although Rio managed to beat them up, they escaped, leading Jyuto to believe that Binzuigumi were aware of their plans.


 * Jyuto got in tough with the informator and threatened him into telling what he knows about Binzuigumi and he revealed that they coerced Rentei Nukagaki (Samatoki's underling) into being their mole by kidnapping his younger sister. After meeting at Rio's campsite, Rio told them that criminals they encountered were his ex-teammates and Jyuto then told Samatoki about Rentei. MAD TRIGGER CREW stormed the Binzuigumi HQ and confronted the clan leader Genno Nouzenkazura, as well as his people, which led to their arrest.

Internal Clash

 * Prior to the Division Rap Battle, Jyuto was suddenly called back to the department to investigate the series of burglaries across the city. As Jyuto couldn't participate in the battle during the investigation, Samatoki and Rio joined forces to assist him, although their attempts weren't successfull. Jyuto told Samatoki and Rio to consider replacing him for the battle but they ultimately refused, stating that they need him for the battle.


 * Suddenly, they were approached by Iris Innocent Traiter who informed that them that Jyuto's colleagues, Hodogaya and Nagatsuta were scheming against Jyuto. With Iris' help, Jyuto found out that they were working with the culprit all along and planned to get rid of him and take all money for themselves. MAD TRIGGER CREW didn't let Hodogaya and Nagatsuta kill the culprit and took them down. Jyuto gave them ultimatum: he won't tell the department about what they did, but in exchange they have to work for Jyuto.


 * With the case closed, Jyuto joined MAD TRIGGER CREW and together they won the preliminaries, advancing to the Division Rap Battle.

Division Rap Battle

 * After four Division representatives arrived at Chuohku for the battle, the leaders engaged in a battle only to be stopped by Ichijiku. Samatoki was enraged at Ichijiku interrupting them but Jyuto stopped him, reminding him that she has the absolute authority over them.


 * Before the battle with Buster Bros!!!, Samatoki told Jyuto and Rio about his beef with Ichiro and what he did to his younger sister. Jyuto assured him that he can focus on Ichiro, while they will take his brothers. In the battle, MAD TRIGGER CREW gained an upper hand, as Jyuto relentlessly attacked Jiro, however, both Jyuto and Rio were taken down by Ichiro. Samatoki still managed to defeat him and win the battle.


 * During the final battle with Matenro, Jyuto confronted Doppo and MAD TRIGGER CREW were able to withstand their attacks and hit back. However, Matenro launched a powerful group verse, so Jyuto and Rio pushed Samatoki back and took all the damage themselves, saying that Samatoki must fight. Jyuto and Rio were defeated and despite Samatoki defeating Hifumi and Doppo, Jakurai managed to take him down, so Matenro became the champions.

Confrontation with Chuohku

 * After the Division Rap Battle, Samatoki and Rio planned to use their chance to confront the Party of Words (Samatoki was searching for Nemu, while Rio wanted to save his commander), despite Jyuto's protests. They were interrupted by the official who informed them that Otome Tohoten wants to see them. However, Rio found out that the Party set up an ambush, so MAD TRIGGER CREW took the confrontation. They also found out that the Party attacked Buster Bros!!! and Matenro as well, so they made a temporary truce to escape from Chuohku.


 * The teams were approached by Iris, as well as T.Rex and Tom Whisper Weathercock who offered to show them the way out. However, it was revealed that they were a team known as Secret Aliens and they worked for Ichijiku. Secret Aliens confronted the teams, as Ichijiku used the Canceller to deactivate their mics but with Fling Posse's help, they managed to escape. While Jyuto and the others were too worn out, the leaders took the chance to battle with Secret Aliens, although they were having problems. However, their teammates joined them and together they defeated Secret Aliens.


 * Afterwards, a group of Chuohku troops led by Ichijiku arrived to capture all of them. The teams prepared for a confrontation, however, Otome suddenly ordered Ichijiku to withdraw. Shortly after, the teams parted ways with Secret Aliens and ended their truce, clashing in yet another battle.
