Sushi Samurai

In Mid Edo-Period Japan, the time of history when swords were replaced with coins.
Rapidly changing Edo economy caused the prices to skyrocket, causing many Samurai to fall into poverty.
Sushi-Zaemon, a lower class Samurai, was barely living with his nickel and dimed daily job of making paper umbrellas.
One day,a new sushi joint "Dai-Foodgo Sushi" opened in the neighborhood.
As an opening ceremony, it held a sushi glutton challenge.
First of all, Edo-economy was struggling, because the value of rice bottomed to the ground.
Rice was Sushi-Zaemon's salary, but it was not worth much as a pebble.
Sushi-Zaemon had an idea. If he can fill his stomach for free, that will save on his food expense.
At the same time, by consuming as many rice as he can, that will help to recover the value of the rice in the market.
This is not simply for himself, but was a mission for Sushi-Zaemon to save Edo.
Challenge Accepted.
I am the slayer of sushi, hence now call me the "Sushi Samurai".
Will Sushi Samurai be able to eat out "Dai-Foodgo Sushi" and bring glory back to the Samurai of Edo!?
