In Japan, in a village in Hokkaido, lived the respectable but poor Aito family. For the second year in a row, their rice harvest was dwindling, and it was becoming increasingly difficult for Ait to support his family. One evening, while sitting on a stump and looking out over the rice fields, he saw a strange fox speeding past. The next day, while Ait was working in the fields, his wife brought him a modest dinner. After wiping off his sweat and sitting on a stone, he began to eat rice, but soon he saw the same fox crouching nearby again. Her sad eyes looked straight at Aita, who couldn't stop wondering that this fox had many tails. Thinking that the fox was hungry, he came closer and gave her the remains of his meal. The fox hurriedly crept up to the food and, having swallowed everything in one bite, scurried off like a madman, waving his beautiful multi-colored tails. This kind of communication between the fox and the man became closer day by day, and the harvest of the Aito family also grew. Zenko became not only a symbol of their family's prosperity and harvest, but also a real member of the family.
