In a world consumed by conflict, the Party of Words introduces Hypnosis Microphones, devices that wield the power of lyrics to manipulate minds and bodies. With traditional weapons outlawed, gangsters, terrorists, and the military rely solely on the potent combination of words and music. Amidst this turmoil, the all-female Party of Words seizes control of the Japanese government, confining women to Chuuouku while men engage in rap battles for supremacy beyond its borders. As the Party of Words recruits former members of The Dirty Dawg, a renowned rap crew, a legendary showdown looms—one where pride and honor, not land or warfare, hang in the balance. As the inaugural Division Rap Battle approaches, these seasoned rappers are primed for a clash unlike any other.
