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)
