The Yamada sisters, Kyo (15) and Asu (9), are students studying in secondary and primary schools respectively. Their mother passed away and their father ran away after incurring gambling debts. Despite the difficult circumstances, both of them decide to overcome the unhappiness and welcome their days with enthusiasm and pride. Fortunately, with the change in the law system several years ago, Kyo is able to study and simultaneously take temporary jobs (such as distributing newspapers and tutoring) to make ends meet. On the other hand, Asu takes charge of household chores, prepares meals, and manages the finances to assist her older sister. Surrounding them are also good and kind neighbors such as the novelist, Saegusa-san, and the aunt at the public bath who watch over them. Although life is difficult and at times painful, the sisters are happy to have each other.
