Lucy is requested for a job because of an unknown key. Soul Society has sent a group to find and protect these keys. What will happen when these two groups meet? How will they react when the keys answer Lucy? Why is a group lurking in the shadows and what do they want with Lucy?

Lucy was sent to an unknown world she thought was Edolas by a certain dark mage during their mission. When she woke up, she was greeted by a group of men wearing signature black cloaks. She was forced to do things against her will. But she would not submit to him. She would do everything just to go back to Earthland, with Natsu and Gray.
