A boy named Ichimura Kazuya is a marathon runner. He has a part-time job as a paperboy to support his mother, who loves to buy expensive kimonos. His parents constantly argue, with his father never giving his mother any attention, so his mother uses the money she believes her husband secretly gives her (it is actually Kazuya's money) to buy kimonos to hopefully catch his father's eye. Kazuya thinks that it is the salesman Saito's fault that his family is in this state, as Saito flatters his mother excessively so she can buy more kimonos from him. He sends Saito to Hell, only to find another salesperson replacing him and pampering his mother with flattery.
