The Party of Words released "Hypnosis Microphones"—devices through which a user feeds lyrics that may alter the listener's brain and even cause bodily damage—to the public in a world overrun by war and turmoil. Hypnosis Mics have converted words and music into the sole weapons used by gangsters, terrorists, and the military, with physical weapons being prohibited. The all-female Party of Words controls over the Japanese government as a result of swooping in amid the pandemonium. In Japan, women currently dwell in Chuuouku, while males fight over territory outside the ward in rap fights. With uncertain motives, the Party of Words begins to assemble former members of the now-disbanded famed rap team The Dirty Dawg to establish a new group.
