Aya inherited the old wallet left by her mother and unexpectedly discovered that it could connect a parallel village where supplies were scarce. The people there are simple and honest, but they have fallen into temporary difficulties due to natural disasters. Aya used her purse to transport food, seeds, medicines and farm tools to the village, helping the villagers rebuild their homes. The villagers were grateful for her kindness and used their own crafts and specialties to give her the warmth that is rare in modern cities. The elders in the village silently guard the safety of the passage between the two worlds, and the young adults who go out are also working hard to return home and bring back new technologies. The two worlds are at opposite times and cannot be crossed by living creatures. Only Aya can undertake this special "messenger" job.
