==Drama Tracks/Manga (main storyline)==
===Military Service===
:As a member of the Navy, Rio joined the Special Extermination Operation Unit under Ansho Iojaku’s command to fight terrorist groups. During his service, Rio and his unit were given prototype Hypnosis Mics, customized for military use. However, soon after the Party of Words overthrew the government, Rio’s unit confronted them, however, they were defeated as the Party of Words used the Hypnosis Canceler to neutralize them. The military was demobilized and Ansho was arrested, while Rio and his unit had to go AWOL.
:Rio camped in the forest near Yokohama harbor where he was living a survival lifestyle, using wild animals and insects as ingredients for his cooking. One day, he found Dice Arisugawa collapsed from hunger. Rio brought Dice to his campsite where he treated him to some of his cooking. Dice was frequently visiting Rio to grab a meal and Rio even once lent him a large sum of money, thinking that he needed battle funds (although Dice was just going to gamble).
===MAD TRIGGER CREW===
:Rio was approached by Jyuto Iruma who was working on his case for the police’s behalf. Impressed by Rio’s skills, Jyuto offered him to discuss the cooperation with his teammate. Later, when Jyuto brought Samatoki Aohitsugi to his camp, Rio assumed that he was an enemy and told him to stay away which provoked his hostility.
:Rio and Samatoki encountered each other in a rap battle and Rio managed to withstand Samatoki’s verse and damage him in return. However, they had to stop when the group of criminals surrounded them in an attempt to steal Rio’s mic and sell at this black market. Rio joined forces with Samatoki and Jyuto and together they defeated all their enemies. Rio thanked Samatoki and Jyuto for the assistance, saying that he is in debt to both of them. Impressed by Rio’s skills, Samatoki offered him to form a team and Rio accepted, so together they formed MAD TRIGGER CREW to represent Yokohama Division. Rio also invited them to their campsite to treat them to his cooking.
===Aborted Operation===
:Before the Division Rap Battle preliminaries, Rio was approached by his ex-teammate, Kubiki who came up with a plan to invade Chuohku and liberate Ansho. Rio, however, was hesitant to join Kubiki when he suggested doing it together, and took some time to consider. During the preliminaries, Rio was too caught up in thoughts and couldn’t collaborate much, while Samatoki and Jyuto defeated the opposing team themselves.
:Eventually, Rio went to meet Kubiki and his unit while they were preparing for the attack. Rio stated that their plan is doomed to fail due to Hypnosis Cancellers owned by the Party of Words. Kubiki didn’t listen to Rio’s warning and continued to prepare for the attack but Rio, determined to stop them, confronted Kubiki and his unit, despite being outnumbered. However, Rio was joined by Samatoki and Jyuto who followed him and together, MAD TRIGGER CREW defeated Kubiki and his unit.
===First Rap Battle===
:Prior to the Division Battle, MAD TRIGGER CREW arrived at Chuohku where Samatoki reunited with his ex-The Dirty Dawg teammates. Rio met with Dice and also treated Doppo Kannonzaka and Hifumi Izanami to his lavender drink, and while Doppo gladly drank it, Hifumi collapsed from the taste.
:Samatoki got into a confrontation with Ichiro Yamada and despite Rio and Jyuto’s attempts to stop Samatoki, they got into a battle. However, the battle was stopped by Ichijiku Kadenokoji who used the Canceller, which made Rio concerned that the Party of Words succeeded in the development process.
:At Chuohku, Rio and Jyuto encountered Jiro and Saburo Yamada at the restaurant and Jyuto got into a quibble with them. Jiro challenged them to the battle in which Rio and Jyuto mercilessly attacked Jiro before Saburo joined and they managed to fight back. Jyuto ceased the battle and discussed with Rio that Jiro and Saburo might pose a threat.
:During the rap battle between Buster Bros!!! and MAD TRIGGER CREW, Jiro and Saburo were defeated and Ichiro managed to take out both Rio and Jyuto, however, Samatoki defeated Ichiro, so MTC secured the victory. At the final battle against Matenro, Doppo used his Rap Ability to take out Rio and Jyuto, while Jakurai managed to defeat Samatoki, leaving Matenro as the champions. After the battle, Samatoki thanked Rio and Jyuto for sticking with him and said that the next victory will be theirs.
===Grasshopper Traffic===
:Rio was approached by Samatoki and Jyuto who told him about the situation with the Grasshopper drug in Yokohama, asking Rio to assist them in taking down the dealers. Rio asked Jyuto why he didn’t use his police contacts and Jyuto said that this is a personal matter, telling him a story about the reasons he started his war on drugs. Rio agreed to help Samatoki and Jyuto but not before cooking a meal for them, much to their horror.
:Led by Jyuto’s intel, MTC arrived at the Minato container yard where a large transaction was reported to happen. Rio suggested investigating the area before launching an attack, however, they heard voices at the other side. They found out that Fling Posse also came to the container yard with suspicious bags. Jyuto demanded them to show him contents of their bags but Gentaro Yumeno refused, making Jyuto believe that they were working with the drug dealers.
:MAD TRIGGER CREW and Fling Posse emerged into a battle, as Rio confronted Dice, although neither of them wanted any harm to each other. 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 Rio 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 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.
: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.
===Chuohku Intervention===
:After the incident at the container yard, Rio noticed something suspicious in Ichijiku’s words and decided to investigate. Rio hacked the Chuohku server and dug up some information, concluding that the Party of Words only possesses a handful of Cancellers due to the complicated development process. 
:However, Rio also discovered that they established the production of the Hypnosis Mics outside of Chuohku, despite their advanced security systems. Rio then traced their financial operations and found out that the Party of Words is transferring large sums of money to some third party who was handling the Hypnosis Mic production.
:Rio informed Samatoki about his discovery (Jyuto didn’t respond to his call) and asked him for assistance to find that third party, as they might be a key to taking Chuohku down. Samatoki agreed to help him, however, they couldn’t discuss it further as they were interrupted by Jyuto’s call who told Samatoki to run away immediately. However, it was too late, as the group of Party of Words officials, led by Samatoki’s sister, Nemu, arrived to arrest him.
:Nemu stated that Samatoki violated the law of using the Hypnosis Mic against the individual without one, and although Rio argued that there are plenty of similar cases, Nemu replied that they have solid evidence this time. The officials attempted to apprehend Samatoki, however, Rio stopped them and pressed Jyuto into confronting Nemu who was abusing her power to take Samatoki out of the picture.
:Rio and Jyuto then turned to Samatoki and didn’t let him fall into despair and convinced him to fight back. MTC confronted the officials, as Rio and Jyuto managed to take out Nemu’s subordinates, while Samatoki confronted her personally. Nemu suddenly was contacted by Ichijiku who ordered her to withdraw, what she did, leaving MTC off the hook for this time.
===The Hunt for the Leads===
:While going through the information he extracted from Chuohku's server, Rio got in touch with Kubiki to discuss a plan to liberate Ansho from the Special Prison. Rio came to the conclusion that they can't infiltrate Chuohku on their own, so he decided to deal with him by himself, while Kubiki would support him with information and resources. After digging, Kubiki informed Rio that Hitaki Tsumabira was in charge of the prison before the incident at the container yard, and she could have the information they need.
:Later, Samatoki and Jyuto arrived at Rio's campsite to discuss their situation: Samatoki's clan patriarch was arrested and Jyuto was fired from the department while chasing the powerful drug lord. Rio and Jyuto came to the conclusion that Tsumabira is involved into that as well and they need to track her down. As Kubiki told Rio about Tsumabira's hideout, he and Samatoki went to find her, while Jyuto needed to resolve his issue with the drug lord.
:Rio and Samatoki arrived at the place where they confronted Tsumabira and Misago Haebaru, who were behind of the drug trafficking in Yokohama. After the battle, Tsumabira and Haebaru attempted to escape, however, Rio caught Tsumabira and took her out, before extracting the information about the prison from her.
:After the situation got resolved and Jyuto got his job back, they gathered again. Rio told them about his plan to liberate Ansho: he must enter Chuohku's main database but for that, he needs to enter the Party's tower that is open only for the winners of the Division Rap Battle. Rio said that he will carry out this mission on his own, however, Samatoki refused to stand still and said that they will do it together as a team.

===Intercepting the Drug Deal===
:Rio joined Samatoki and Jyuto on a mission to intercept the drug deal in Yokohama harbor, which involved Samatoki's rogue underling Utashiro. When the dealers tried to escape after bring confronted by Samatoki and Jyuto, Rio used the explosives he planted to cut off their exit route. With no way to escape, Utashiro and the others decided to fight but MAD TRIGGER CREW successfully took them down.
:Jyuto contacted the police for backup to apprehend Utashiro and other dealers. While he and Samatoki were discussing the situation, Jyuto's stomach growled and Rio immediately assumed that they're hungry. Rio told them to go back to his campsite so he could treat them to his cooking, although Samatoki and Jyuto tried to talk their way out.
