In the H Age, war has been abolished, & women run the government. Men now compete in rap battles with hypnosis mics that can inflict psychic damage on their opponents. Watch as 4 promising teams from Tokyo take care of business in their own divisions.

A team "Buster Bros !!!" formed by three brothers. The eldest son and leader, Ichiro Yamada, dropped in at a cafe in Ikebukuro for work. However, a man with an illegal microphone appears there and stands up, and Ichiro becomes a hostage with the customer of the store and gets involved in the incident. Ichiro, who didn't carry the microphone at the wrong time, has no way to resist the criminal ... Younger brothers Jiro Yamada and Saburo Yamada notice the appearance of their older brother in the newsreel and start running to the scene.

When Doho Kannonzaka, who was exhausted from overtime, returned home, there was a strange man's corpse in the room. When the housemate, Izumi 123, confirmed the corpse, a tie was wrapped around his neck. When he heard the siren of the approaching police car, Jinguji Jakurai, who had just come to see them, sensed the situation and left the apartment with them in the car. The three, who thought that Doppo was fitted to someone, began to move to find out the truth of the case with their own hands.

At the call of the Iruma Gun Rabbit, Sakuma Aoki and Mason Tokushima gather at the office of the Yakuza "Fire Warbler" in Yokohama. According to Gun Rabbit, there is a casino of the flight pursuit group that is hostile to the Shima of the fire group that Sakumaki divides, and drug trading is done there. Gun rabbits aiming for career advancement ask for cooperation from the two in order to monopolize the credit for crushing the transaction. Sakuma, who wants to crush the flight pursuit group, and Riyu, who cannot overlook the insecurity as a soldier, decides to help the gun rabbit.

The words "Horror! Ghosts infesting the Shibuya Division" on TV. Amemura random number who looks frightened with his face turned away. Emperor Arisugawa noticed the situation and made fun of the random numbers, but the random numbers seemed to be stubborn and said, "There are no ghosts, I'm not scared." Watching the situation, Gentaro Yumeno proposes to bet whether or not there are ghosts. The three went out to the city of Shibuya at night to find out the truth ...

Finally, the division battle qualifying was cut off. While the thoughts of "Buster Bros !!!", "MAD TRIGGER CREW", "Fling Posse", and "Matenro" participating in the qualifying are mixed, there is a note on the net saying "Crush the division battle". The three "Buster Bros !!!" rush through the city of Ikebukuro to thwart the attempt.

Tom, Iris, and Rex split into three hands and head for coverage of "Matenro," "MAD TRIGGER CREW," and "Fling Posse." And on the day of the Shinjuk division "Matenro" qualifying. I had to go home on time to participate in the qualifying, but the section chief asked me to do a lot of work today. Meanwhile, a colleague appears who supports me, "I like the rap style of self-reliance."

The eve of the Yokohama Division "MAD TRIGGER CREW" qualifying. In order to finish the investigation by 10 am when the qualifying starts, Gun Rabbit relies on Sakumaki and Riyu, but the investigation is difficult because he cannot get any clue about the case, and the qualifying participation of Gun Rabbit becomes doubtful. On the other hand, in Shibuya, a random number was used to inform him that he had abducted the Emperor.

The four teams "Buster Bros !!!", "MAD TRIGGER CREW", "Fling Posse", and "Matenro" who won the division battle final tournament were gathered in front of the main gate of Chuo Ward. Former members of "The Dirty Dawg" (commonly known as TDD), Ichiro and Sakumaki, random numbers and Jakurai glares at each other from their former ties.

Random numbers called by Kanji Yukoji Fig before the battle. In order to make Jakurai's abilities belong to the Konoha Party, he is instructed to brainwash Jakurai using the powerful hypnotic "Authentic Hypnosismic". However, there is a price to pay for its powerful output ....

Before the final battle, Sakumaki sees and chases his younger sister, Gojo, who should be in the Chuo Ward, but disappears into an area that is off limits to anyone other than those involved. I was struck by a lone thunder who happened to be there when I was about to rub, and decided to talk. On the other hand, random numbers that disobey the orders of figs try to escape from Chuo Ward.

After the final tournament, the staff of the Konoha Party will visit each of "Matenro", "MAD TRIGGER CREW" and "Buster Bros !!!". They say they will guide them to the Prime Minister, but when they sense the danger, they try to escape from the spot.

The true identity of Tom Iris Rex is the warrior "Secret Aliens" who helps governments and revolutionaries in each country. In order to protect the order of this country, he was hostile to Ichiro and his friends. Ichiro, Sakumaki, and Jakurai and others escaped from the Chuo Ward because of their lives, but Tom applied for a rematch with "Fling Posse", who had been caught due to a power outage to help them.
