My name is Shisan. After the war, this city is full of people whose body functions have been expanded, called "Expanders". I make a living here by "dealing" with issues related to the Expanders. A man visits the office of Shisan, the Expander with a gun for his head. The man, who is being hunted by the police as a kidnapper, asks Shisan to protect a child he kidnapped. What will Shisan decide to do? The sci-fi tough guy comic told by the muzzle of a gun with the smell of gunpowder begins here! !
