Before Ichirou Yamada, Samatoki Aohitsugi, Ramuda Amemura, and Jakurai Jinguji came together, they were members of three separate units: Mad Comic Dialogue, Naughty Busters, and Kujaku Posse. Aside from rapping and defending their respective division borders, these men find themselves competing against each other in eating contests, investigating haunted houses, and solving petty crimes. Even when they are not busy spitting hot rhymes and annihilating enemies with their flawless lyrical flow, the depictions of their lives are anything but mundane.
