In the town of Nerima, the boisterous Hideki and his stoic brother Ichiro operate a daikon radish farm alongside Mako, their bubbly yet vain cousin. The trio dreams of accumulating enough funds to construct their own concert hall, where their band—the Nerima Daikon Brothers—would perform and hopefully achieve stardom. However, their farm and Ichiro's job at a host club are not generating money quickly enough to satisfy them, prompting them to turn to get-rich-quick schemes. Their plans typically involve tracking down evildoers and then stealing their ill-gotten gains. Yet, while they usually do put a stop to the villains, they always end the day no richer than before. Nevertheless, neither these failures nor interference from the policewoman Yukika Karakuri can come between this trio and their dream! With assistance from gadgets provided by the rental shop owner Nabeshin, the Nerima Daikon Brothers get themselves into and out of all kinds of ridiculous situations through their boisterous singing and comedy.
