In the future, the development of massive war machines called Objects have rendered 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 only Objects can destroy Objects, modern warfare is reduced to duels between Objects, resulting in shorter, cleaner, and safer wars. However, this all changes when two regular soldiers from the Legitimate Kingdom, Qwenthur Barbotage and Havia Winchell, use their smarts and ingenuity to destroy the "Water Strider" Object of the Faith Organization all by themselves. Having proven that Objects created by man can also be destroyed by man, Qwenthur and Havia are thrown into a new world of harrowing adventures and dangerous suicide missions, while together with Qwenthur befriending and saving the Legitimate Kingdom's Elite Melinda Brantini, of the Object "Baby Magnum."
