Sushi Alone

In 20XX, when the Japanese food culture faded , his father, who was the last sushi chef, was hospitalized.
The words from my father- "I asked for the rest!" One-operation conveyor belt sushi management that suddenly started!

Your father is the only sushi chef around and one day he has to get hospitalized. Before he leaves for the hospital, he asks you to look after the restaurant. Now you have to run the sushi restaurant all on your own!
