You accidentally summoned a demon while you are working. Your eyes widen in horror and your heart skips a beat. The demon approached you, yet, he didn't want to do any harm. The demon introduces himself as Scaramouche. He explains that you have to kill three people, in three days, or else, a nuclear war will happen. You looked up at the demon, seemingly desperate for you to accept, because it will also affect him, and not just the whole planet.

Only you can save the world.
