The main character is Junpei, a young man who goes to university. His name is Junpei.
After spending an ordinary everyday life, he becomes involved in a great conspiracy that even he did not expect.
One day when I wake up, it is a strange room.
It seems to be a room of an old passenger ship.
The first thing that caught my eye was the letters written on the door.
It was marked [5] in red paint.
Junpei is standing alone in a locked room.
The last memory before I woke up brought to my attention the image of a mysterious man wearing a gas mask.
"My name is 0. From now on I am going to play a game.
[Nonary Game] A game of life and death."
Nonary Game?
I don't understand why, but anyway it seems that there is no doubt that the person named 0 is the one who took Junpei and others away.
Yes, Junpei "Guys".
There were eight men and women in the ship besides Junpei.
According to the story of 0, there is a "9" door somewhere inside the ship and you can't escape from the ship unless you open it.
The time limit is nine hours.
If you don't escape within nine hours, the ship sinks.
Nine people, nine doors -.
The extreme escape drama opens now.
