This is the first title by NONSUGAR, which is comprised of staff from the defunct TAILWIND. One day, the giant ‘world tree’ appeared and it was controlled by an organization known as the ‘Visioners’ who massacred innocents to achieve the end of the world. However, one girl and her soldiers stand in their way. They are Shirayuki-hime and the ‘seven heroes’ that protect her. Yuu is a normal student that has a high sense of justice who gets involved in this epic battle. Will he be the one that can lift the curse bestowed on Shirayuki-hime?
