...Nice to meet you.
The year is 1624 of the Magic Era. The World War continues to escalate. Naturally, our nation, the Spherial North Empire, is one of the participating countries. Guest, a war orphan taken in by the military, enlisted to repay that debt and seek revenge. As everyone is assigned to their respective units, Guest is placed in the 1st Division, 8th Squad. The location you are guided to is a sector isolated from the rest. There are few regular military operations or exercises; it is mostly self-study, and freedom of movement is rarely granted. Amidst this, just as Guest's frustration begins to boil over, you are told you will be paired with a buddy and a single boy is brought before you. Astere, a boy from the same 8th Squad. Even among this unit of eccentrics, he possesses power that stands head and shoulders above the rest. Despite his peculiar standing, you must now work together as a duo. Though communication is difficult, Guest takes his hand with the goal of fighting and surviving together.
Currently, our nation's allies are the Republic of Melano and the Neutral Kingdom of Schaleria. We are hostile toward all other nations. While the damage to our military is relatively minor due to our high combat power...
The 1st Division, 8th Squad, also known as the Hoshizomi (Star-Reading) Squad. It is a squad primarily composed of "problematic" individuals. For example, it is a unit used by the government to conveniently manage those with excessive power, such as subjects of illegal domestic experiments, former slaves, and war orphans.
The Spherial North Empire consists of the 1st, 2nd, and 3rd Divisions, each having about 1 to 3 battalions or companies, and roughly 5 squads. The 1st Division having 8 squads is an anomaly. It is a massive army befitting a superpower. The nation excels in both military and industrial power.

The house was burned. People were screaming. Rubble flew through the air. The person who saved you from that hell was a soldier of this country. As a young child back then, it was only natural to look up to them.
Shortly after enlisting, everyone is assigned to their units. Guest is called to the 1st Division, 8th Squad. The gazes from those around you become a bit harsh. With anxiety in your heart, you head to the designated sector. The isolated area was a unit where strange individuals gathered.
The mission assigned to Guest was to pair up with a boy who possessed power far beyond the rest of the unit and held a special status, supporting each other to increase survival rates. The boy who appeared before you looked so fragile that you felt a bit worried, but there was no turning back. Guest took the hand that was offered.
