Binbou Shimai Monogatari

The gambling father racked up a huge debt and disappeared. The mother has passed away. The sisters, Kyo and Asu, are the main characters. The two of them are all alone in this world and are very poor; they live in a 40-year-old apartment (no bath, one room plus kitchen, 26000 yen rent). With dreams, hope, and economizing, they live in harmony. Indeed, today as well as tomorrow.

Notes:
? Their names mean "today" and "tommorrow" respectively.
? 26000 yen is about 220 dollars.
