The protagonist, Hideki, is a 25 year old owner of a daikon field in the Nerima ward of Tokyo, a region famous for growing Daikon. As children Hideki, Ichiro, and Mako made a pact to one day perform in a concert in a dome where the Daikon field now sits. One of the running gags in the series is Hideki's crush on Mako, his cousin. He would like to marry her, but he believes that he cannot because of the Japanese constitution; he is even tricked by a lawyer who tells him that he can change the constitution. (Source: Wikipedia)

Hideki, leader of the Nerima Daikon Brothers, has a dream to build a dome in his hometown of Nerima to hold a concert for his band. Together with his cousin, Mako (whom he has a crush on), Ichiro, and Pandaikon (a panda he found in his yard that resembles a daikon), they strive to make money any way they can, and in the process, rid the world of evil-doers and steal their money in the process. With help from a rental guy, Nabeshin, who rents them outrageous items that always seem to help them defeat the bad guys, the Nerima Daikon Brothers sing their way to victory but always manage to lose the money they stole in the end. Even under the investigation of Inspector Karakuri, they never fail to fight for justice the Nerima-Daikon way.

The somewhat rough Hideki, former idol Mako, and cool host Ichiro live together on a stage in the middle of a daikon field. Their dream is to build a concert dome there to perform blues music to the masses, but they're just too poor to get anywhere.
