One chapter in the saga of Shima Kousaku, salaryman at Hatsushiba Electric.

In this part of the series, Kousaku has just started working at a branch office for the company doing an unexpected amount of menial labor when a chance meeting with the company president leads to his dearest wish being granted as he is transferred to the central office. Not all is well there, though, as he becomes involved in the complicated affairs of his colleagues, whether in business or in romance. In spite of everything, however, he retains his faith in the company and an unflappable optimism.

Kaji Ryusuke is a second son of a great politician. However, his father and Kaji's brother both pass away from a car accident. Now, those who supported Ryusuke's father want Ryusuke to carry on the family business as a politician.
At first, Ryusuke tries to get out of the responsibility, but he eventually enters an election to become a politician.
This manga will view Japanese politics from Kaji Ryusuke's viewpoint.
