Heavy Object is a Japanese light novel series. In the future, the development of massive war machines with spherical main bodies called Objects, due to their firepower and, most important of all, their integrity, have rendered all manner of conventional warfare, and even tactical nuclear weapons seemingly obsolete. As a result of this military upheaval, all of the nations of the world have fractured into four coalitions which constantly wage war on each other; the "Legitimacy Kingdom", focused on tradition; the "Capitalist Corporation" (in the anime the "Capitalist Enterprise"), which values profit; the "Information Alliance" (in the anime the "Intelligence Union"), focused on knowledge; and the "Faith Organization", which values religion above everything else. With the perception that Objects can only be destroyed by other Objects, modern-day warfare has been virtually reduced to duels between Objects, resulting in shorter, cleaner, and safer wars. However, two regular soldiers from the Legitimate Kingdom, Qwenthur Barbotage and Havia Winchell, change all of this when, convinced by Qwenthur, they use their smarts and their ingenuity to successfully destroy the "Water Strider" Object of the Faith Organization all by themselves. Having now proven Objects created by man can also be destroyed by man and not just by other Objects, Qwenthur and Havia are thrown into a new world of harrowing adventures and dangerous suicide missions, with Qwenthur also befriending the Legitimate Kingdom's Elite Melinda Brantini, pilot of the Object "Baby Magnum", having saved her during the events of which resulted in the destruction of the Object of the Faith Organization.
