In the year 3040, men built space colonies to control the population, and discovered aliens along the way. There are two types of people aboard the colonies, "Engineers", who build weapons, armor, and vehicles, and also research alien technology and substances, and "Hunters", who are sent to planets to gather the resources and to kill whoever they are commanded to kill. Nestagen Jung is one of the Hunters aboard the 51-Epsilon, who was given a cybernetic arm. Along the way in her story, she tries to unravel the secret behind a mysterious new planet that seems to be the home of all fears.
