H-Era, Year 3: Following the disbandment of The Dirty Dawg, former member Dr. Jakurai Jinguji receives an invitation from the Party of Words to participate in the first iteration of the Division Rap Battles—a new initiative that puts the best of each division against each other in a head-to-head battle for territory, pride, and a large monetary prize. The new rap contest is an opportunity for Jakurai to exact revenge on Ramuda Amemura, another former member of The Dirty Dawg who now hates him. With salaryman Doppo Kannozaka and Shinjuku’s number one host, Hifumi Izanami, Jakurai forms his own rap group, Matenrou, to compete in the Division Rap Battle.

Elsewhere, Ramuda is forming his own crew to participate in the same competition. Teaming up with gambler Dice Arugisawa and author Gentarou Yumeno, the trio form Fling Posse to represent Shibuya. As the two teams face off in the tournament, Ramuda and Jakurai find themselves entangled in a complicated situation with the new powerful government of Japan. Having taken a special interest in Jakurai, the Party of Words will do anything it takes to ensure his cooperation. It will take more than just superior rap skills to uncover the truth behind what happened to The Dirty Dawg and the government’s true intentions.
