Miyazaki Shogo suddenly appeared at Smile Agency, an advertising agency facing a management crisis, six months ago and took up the post of president. It seemed like this would get the company back on track, but a laid-back personality, more interested in his hobby of making plastic models than his work, spread throughout the company, and the company began to decline further. Then, at the direction of Sakuma Shigechiyo, chairman of Rockwell, the parent company of Smile Agency, "Demon Girl" Mashima Naoko and "Super Laid-Back Man" Sawada Shotaro are dispatched. Miyazaki, Mashima, and Sawada may seem like completely different types of people, but they actually have something in common. Their coming together causes a miraculous "chemical reaction" at Smile Agency, and they bring about a revolution in the company while drawing in the other employees.
