"Three souls, one mind,
Shaping history with our style!"

The dawn of the H. Era note : All weaponized conflict has been eradicated.
The conflict was replaced, not by the military forces, but through the use of specialized microphones which directly affect the mind. Lyrics recited through the device can cause a variety of different effects on a target via their nervous system.
The name of this new technology: the Hypnosis Microphone.
Men are forced to live in areas outside the Central Ward note  called Divisions. One crew represents each division to battle it out and expand their territory. These men put their pride on the line as the Territory Battles begin.
In this new world where words are literally mightier than any weapon, rap is power. (translation by hypmic_en)

Hypnosis Mic: Division Rap Battle is a music franchise by Otomate, Idea Factory and King Records. Beginning in 2017, the franchise consists mostly of character song albums, with drama tracks telling most of the story. The first Battle Season began in 2018, pitting Buster Bros!!! against MAD TRIGGER CREW in WAR WAR WAR, and Fling Posse against Matenro in BATTLE BATTLE BATTLE. MAD TRIGGER CREW and Matenro won their respective battles and continued on into the final round, DEATH RESPECT. The crowned winner of the current final round was Matenro.

In addition, three different manga have been announced for the franchise, all of which will begin serializing in December 2018: one focusing on the Buster Bros!!!/MAD TRIGGER CREW rivalry, another focusing on Fling Posse/Matenro, and a prequel manga focusing on the rise and fall of The Dirty Dawg.


A mobile game adaptation was announced at the 2018 Otomate Party, set to release in 2019. It is titled Hypnosis Mic: Alternative Rap Battle. In April 2019, Otomate released a song, History of Hypnosis Mic, sung by Japanese educational rapper Co.Keio, providing a brief history of the series from initial conception to the current (as of April 2019) season for newcomers.

Welcome to the Division!:

  • 20 Minutes into the Future: Aside from references to the hypnosis microphones and Chuoku, there's barely any indication that the story takes place in the future. Fashion trends remain the same, people's everyday lives seem largely unchanged, and Ichiro makes references to New Genesis Evangelion.
    • Apparently, according to TDD manga, the world had just gotten out of World War III, which was responsible for the death of a full third of the world's population, but this major event seems to have barely had any effect on Japan, aside from the establishment of Chuoku. Host clubs still exist.
  • Badass Crew: The Dirty Dawg. It was a legendary rap crew formed two years prior to the story, composed of the leaders of each of the current divisions, but broke up for unknown reasons.
  • Battle Rapping: The entire basis of the plot. Monthly Territory Battles are organized by the Central Ward. The representative crew from each division puts their territory on the line to fight for additional territory and a monetary prize.
  • Call-Back: Aside from the opening speech, Ichiro's first solo lines in WAR WAR WAR are "Ore ga Ichiro (I am Ichiro)", an obvious reference to his solo song, Ore ga Ichiro.
  • Cast Full of Pretty Boys: It's an Otomate series, what did you expect?
  • Chromosome Casting: The main cast consists of all-male rap groups, with most women serving as side characters, family, or announcers.
  • Clothing Damage: Apparently, rap battles fought using hypnosis microphones can cause this, as seen on the DEATH RESPECT album cover.
  • Color-Coded for Your Convenience: The four main divisions are represented by the three primary colors, plus grey.
    • Ikebukuro is red.
    • Yokohama is blue.
    • Shibuya is yellow.
    • Shinjuku is grey.
    • In the past, The Dirty Dawg was represented by the color black.
  • Establishing Character Moment: Division Rap Battle is one for all of the characters, and each division as a whole, as well.
  • Excuse Plot: The premise of the franchise seems like this, as there is really no logical reason as to why battle rapping should have to do with the segregation of men and women in their world, along with a majority of the population being wiped out in a war. The franchise does do its best to gradually build up off of the initial premise with every installment that comes after, however.
  • First-Name Basis: Within the divisions, almost everybody calls their other teammates by their first names, with the exceptions being Saburo and Jiro calling Ichiro "Ichi-nii"/"nii-chan", and Doppo and Hifumi calling Jakurai "Sensei". The women in Chuoku also refer to Hifumi, Doppo, Dice, and Ramuda by their first names, although they refer to Gentaro as "Yumeno-sensei".
  • History Repeats: In a meta sense. Banning the use of weapons and the restrictions that followed on who was felt to be the instigators really caused a lot of disaster in the years following, especially when a new weapon rose to take its place... just like the last time the most well-known weapons were banned in the country.
  • Leaning on the Fourth Wall: The battles between districts are voted on by women all over Japan; this goes for out of universe as well, since the rap battles are put on the official Youtube account for people to decide the outcome.
  • Matriarchy: The new government is initially claimed to be Enlightened, but really falls under Patriarchy Flip.
  • Mind-Control Music: It's all in the mic's name. While the usual methods are still used, they're also shown to be used as tools to convince or calm down a homicidal rampage.
  • Power Trio: Each division's groups are comprised of three members.
  • Shout-Out:
    • In Ichiro's solo, Ore ga Ichiro:
      "This neon rap genesis for a new generation,
      If it's mind-blowing flow and skill you want, that's my job."
    • IKEBUKURO WEST GAME PARK, the title of Buster Bros!!!'s division song, is the name of an urban mystery novel and television series that takes place in Ikebukuro.
    • On April Fool's Day 2019, Buster Bros!!! performed a rap remix of the King of Prism version of "EAZY DO DANCE".
  • Sliding Scale of Gender Inequality: Of the men and women being separated variant, which leads to some In-Universe Unfortunate Implications of what happens/happened to families. Men can only enter the women's district with permission. Their current world doesn't seem to be entirely built on sexism, however, as the background character women observed in the Drama CDs from Chuuoku so far don't seem to have a problem with Hifumi note  or the other male characters. The same can’t be said for the leaders of government itself. Though it’s currently unclear if every government official shares the same views as the Prime Minister.
  • Teens Are Short: Averted. The teenaged Yamada brothers are just as tall as the adult characters, with Ichiro ranking fourth tallest among the cast. Jiro is taller than all the members of Fling Posse, and even 14-year old Saburo is taller than the Ramuda, who is a decade his senior.
  • Tokyo Is the Center of the Universe: All those divisions? Just Tokyonote , as usual.
  • We Used to Be Friends: The ex-members of The Dirty Dawg. However, it may just be the Ichiro-Samatoki and the Jakurai-Ramuda pairs that don't get along anymore, as Ichiro and Ramuda are shown to still be friendly with each other, and Samatoki and Jakurai also seem to be on good terms.
  • Wham Line: From the "Know Your Enemy side F.P VS M" drama track:
Ramuda (over the phone): Yeah, that won’t be a problem. Without any delay. If there is anything suspicious about the other divisions, I’ll report it immediately. Yes, if you can.
Ramuda: Of course, Ichijiku onee-san!
