What is Heavy Object?
Heavy Object (ヘヴィー•オブジェクト Hevī Obujekuto) is a light novel series written by Kazuma Kamachi, who is also famous for the Toaru Majutsu no Index light novel series. The light novels are published under the Dengeki Bunko imprint and are illustrated by Nagiryo, who also provided the mechanical designs for the light novels. A manga was later released, with Kamachi acting as the writer and Inue Shinsuke as illustrator.


In the near future, war has developed into a bloodless game that can be determined by mechanical units called Objects. In a military base located on the frigid regions of Alaska, mechanic-in-training named Quenser learns the ropes of becoming an expert in the field of Objects, and meets one of its elite pilots named Milinda. As their friendship develops, Quenser discovers that the real face of war is merely hiding behind the mask of bloodless defeat and victory...
