In an alternative world, where gunpowder has never been discovered, weapons such as guns have never been invented. Instead, blades are still dominant to this very day. In this world, The Great Empire rose from the ashes in order to reclaim the land that ones belonged to them, but got taken away by the allied countries that feared its might.

Adel Habensburg, a 18 year old boy, managed to enlist into the National Empire Academy for Soldiers, in order to become an Elite Soldier for his country. Elite Soldiers are special units that do not follow the orders of the regular army, but instead fight as small Squads in missions that are assigned to them.

However, in this world, not everything turns out to be as they originally thought. As the swords on the front-lines collide, different ideals do as well. The time will come, when the Protagonists have to choose for what kind of future they want to fight for.
