No Man's War

The Heibun Federation spanned across the western part of Garan Supercontinent, while Duttetian in the east. Between the Heibun Federation and Duttetian Empire exists the Dead Zone; accumulation of chemical weaponries, biological weaponries, and wartime machineries during the three-hundred years Eternal War.

There were two sides to this war:
Heibun Federation was a near-utopian federation of many governor-states led by Chancellor Yoriko Yamaguri. Life in the Federation, despite the war is peaceful thanks to the quality of human resources and natural reserves in the Federation; maintaining resource monopoly. The Eternal War is framed as a "Peacekeeping War"; a battle to crush the evil Duttetian Empire.

The other side speaks otherwise. Duttetian Empire led by Dutte Fransisko von Millner was a bare land. Natural reserves are a precious commodity, and with the lack of proper human resource, Duttetian Empire failed to invest on ecological-protection technology and air filters, giving most of the war's toll to the Duttetian Empire. Yet, the Empire still manage to hold the Dead Zone front with the manpower supremacy, about 950 Duttetians per one Heibunians.

The year is now 1917, and the accumulation of chemical weapons in the Dead Zone has caused death tolls to both forces, until Duttetian Empire introduced the Bluthund: Quadrupedal canine manned war machine with 40mm autocannon on their mouth. The Heibunians countered with Mk. I Scorpion machine: A six-legged hexapod war machine with a 40mm tail-mounted chaingun and a head-mounted 150mm smoothbore cannon. The research and invention of lobotomy has allowed these machines to be controlled by "brains" taken from dead soldiers.

Private First Class Kurokawa Tatsuya(male) and Yasutake Tatsuya(female) are two siblings that fought in the Eternal War. Yasutake lost her life in a trench due to a 40mm round piercing her heart; yet she retained her brain intact. The brother swore that he will avenge his sisters's death.
