The World Ether War was a conflict initially started by the Lienard Empire invading a neighboring state for a precious resource known as ether. The war started out simple, only involving two governments vying over a single small area of importance. However, soon this conflict grew and rapidly expanded as other states began to invade each other, intervene with strange and unethical experiments, or merely collapse with different people vying for power. At the end of the war, this fantasy world was scarred by the aspirations and desires of people born in that world and people transported by the gods from another.

This is a story of Squad 78, a small unit within the Lienard military, composed mostly of non-human combatants save for their commander. They fight and struggle to finally reach the end of the war, but if that ends in survival or death is a conclusion none of them know.
