The story begins with the deaths of ruling party's Fukuoka legislator and his eldest son, his heir apparent, in an accident. It is decided that a by-election will be held, and Kanbayashi Masaichi, the leader of the ruling party, and secretary Miyama Rika conceive the idea of fielding the second son, Asakura Keita, who had been renounced by his father.
After Keita graduated from senior high school, he went on to a university in Nagano because he wanted to live in a place with beautiful stars, and eventually became an elementary school teacher over there. Well-liked by children and satisfied with his beloved star gazing, Keita has no interest in the world of politics. However, at Rika's persuasion and the pressure of his family, he reluctantly decides to announce his candidacy.
Upon returning to Fukuoka, Keita is given a hearty welcome by supporters. The election strategist, Nirasawa Katsutoshi, arrives there. He is guided by the notion "election is the only permitted legal war" and begins Keita's election campaign.
