Three years ago, the prolonged war between the Royal Empire and the Republic of Frost concluded. With both nations far from recovery, Alice L. Malvin, a passionate young woman, leads the Pumpkin Scissors, an imperial army unit specializing in war relief. While on a mission to aid a village held by renegade soldiers, Alice encounters Randal Oland, a scarred former soldier with a sordid past but a kind heart. Inspired by the Pumpkin Scissors' efforts, he joins the team for the mission. During the assault, however, Randal falls into a trance-like state triggered by a mysterious blue lantern. Consequently, he gains monstrous strength and decimates the enemy forces. Despite witnessing Randal's disturbing transformation, Alice invites him to join her squad, confident that his gentle nature will prevail and make him a perfect fit for the Pumpkin Scissors.
