Sakamoto was once considered to be the greatest assassin to ever live, a man who struck fear into the hearts of criminals and that was revered by fellow hitmen the world over. However, one day Sakamoto met and fell in love with a beautiful clerk by the name of Aoi Sakamoto. He became so smitten with her that he decided to leave behind the world of hitmen so that he could be with her. Leaving the order made him a wanted man in the underworld.
