■View of the world

The world has changed.

In December 2019, a new type of infectious disease caused by an unknown virus that occurred in Tokyo quickly spread throughout the country, showing a fatality rate of 40% which turned out to become higher than the Ebola hemorrhagic fever.

Traveling to and from overseas was restricted, and the main road leading to Tokyo, where there were many infected people, was blocked.

In other words, the capital city has been on lock down.

Without an effective treatment, the infection spread from the general public to medical workers, police officers, self-defense force, and eventually reached to the core of the nation.

Major government officials such as the former Prime Minister, the Chief Cabinet Secretary, and the Minister of Health, Labor and Welfare were infected one after another and died.

By that time, the death toll in the country exceeded 200,000.

During the state of high alert, a new government was hastily established. A former infectious disease specialist who discovered a cure for the new infectious disease and saved many lives of severely ill patients was selected as the new prime minister.

The new prime minister has come up with measures against the new infectious disease and economic measures one after another, all of which have produced positive results.

The number of infected people has visibly decreased.

Eventually, the raging new infectious disease came to an end.
