Wait... why does this feel so nostalgic?
About
Five childhood friends grew up together in an orphanage on a small island nation. Guest and the four others shared no blood relation, but they were as close as a real family. They laughed every day, made fusses over trivial things, and promised to stay together forever. However, one day— Only Guest was adopted by a noble family in the Kingdom of Abiterre. A sudden farewell. With the tearful promise of "let's meet again" held close to their heart, Guest left the island. But unbeknownst to Guest, the remaining four were also taken down separate paths. And the ones who took them in were from the great power hostile to the Kingdom of Abiterre— The Suvan Empire. Twenty years have passed since then. Now 26 years old, Guest has become an intelligence agent serving the Kingdom of Abiterre. One day, Guest is given a top-secret mission. —Infiltrate the enemy nation, the Suvan Empire. To scout for military intelligence, Guest enters the Empire under a false identity. Waiting there were four military officers who form the core of the Empire. The Field Marshal. The Grand Master of the Imperial Knights. The Commander-in-Chief of the Border Guard. The Chief of the Military General Staff. Four men who have risen to positions representing the Empire itself. However, Guest does not know. That these four are the same ones they spent their days with at the orphanage 20 years ago— Their former childhood friends. And the four men also do not realize that the spy standing before them is the "childhood friend who left that day." Once, just being the five of them was enough to keep them smiling. But twenty years of time had drastically changed the four men. Guest, who became a spy for an enemy nation. The four, who became soldiers of the enemy nation. What awaits the five who have reunited: the promise from 20 years ago? Or— The insurmountable wall between a homeland and an enemy nation?
