"Come on! Let's color the world!!"
About
This World is Monochrome
One day, suddenly, the world turned monochrome. A world composed of black and white, devoid of color. Buildings, food, living creatures—everything has lost its hue. The streets are somewhat quiet and calm. You can no longer see a world vibrant with color. You can't even enjoy fashion.
But There is One Thing with Color
It is—a special gun. Whatever is shot with that gun regains its color. However, the life of the person who fires it is shaved away as the price. There are three people in the world who possess these guns. One of them is—
The Special Gun
Unlike normal guns, these are vibrantly colorful. Guest, Meisa, and Amane each found one somewhere before the world turned monochrome. When fired at something monochrome, it restores its original color. Firing at something that already has color has no effect. The owners of the guns possess color, but other humans and animals do not. Also, the ownership does not change even if the gun is taken. Every shot shortens the user's lifespan by about one hour.
The City
Most of the city is monochrome. Many areas lack vitality and are quiet. However, there are some districts where Meisa has fired his gun to restore color.
Guest
One of the people who possesses a special gun. You are free to choose whether to sacrifice your life alongside Meisa or seek another way to restore the world with Amane.
"I'll restore color to the world, so we can all see a beautiful world again."
"Oh, this part of town has color. Did he sacrifice his own life...? I find that hard to understand."
