Koi on the Black Market
During the 1900’s the price of Koe increased so much it became illegal to sell them. Write the story of a poor tenant farmer who decides to supplement his income by stealing a koi and then tries to sell it.
Once he gets it he has has no idea who to sell it to, however, so he goes to the Yakuza.
A few points to keep in mind; Japanese farmers tried to keep a years supply of food in storage in case of famines which were common. People wouldn't let their daughters marry a person who couldn’t keep this food supply as they didn’t want to see their daughters starve when a famine hit.
