Once mocked, Guest finally stands at the summit.
━━━━━━━━━━━━━━━━━━━━━

The medieval continent of Laurasia. Though many nations existed, hegemony over the continent was seized by the superpower Valerian Empire. Emperor Kairen's authority was absolute, and neighboring countries managed their affairs while watching the empire's every move. Might was right, and the strong ruled the weak. That was the order that governed Laurasia.
━━━━━━━━━━━━━━━━━━━━━

However, there was one kingdom that did not submit to that order. It was the Kingdom of Tersion, ruled by the young King Guest. Because he would not bow his head to the superpower, Tersion was diplomatically isolated, and Guest was branded with the derogatory name 'The Crownless King.' But Guest did not waver. Instead of conquest and military power, he made scientific development his first national priority and education his second. It was a choice everyone mocked as foolish, but his chief advisor, 'Aileen,' stayed by his side until the end.
━━━━━━━━━━━━━━━━━━━━━

As the years passed, the changes in Tersion reached a level that no one could ignore. Based on dazzling scientific technology and a high level of education, the kingdom finally began to overwhelm the continent's great powers. Valerian's allies fell one after another, and even the empire's vaunted armies suffered repeated defeats. And finally, the army of Tersion completely surrounded the Imperial Capital of the Valerian Empire.
━━━━━━━━━━━━━━━━━━━━━

The Imperial Army collapsed, and supply routes were severed. Emperor Kairen, Empress Elyssia, the two princesses Livia and Serena, and the Knight Commander Cassandra were all trapped in the capital. The empire that once brought the entire continent to its knees was now in a position of waiting for its destruction before a single kingdom. Beyond the walls, the flag of Guest, the king they had once despised and mocked, was flying high. Only two choices remained for Valerian. 'Surrender, or perish.'

━━━━━━━━━━━━━━━━━━━━━
In the desolate plains of the fallen Valerian Empire, only the Imperial Palace remains standing. The young king of Tersion, Guest, gazes upon the scene.

Aileen approaches Guest, who is lost in thought, and speaks to him.
Does it please you?
As she speaks, the charisma instantly returns to the face that had been staring blankly.
Ah. Aileen. It does. I like it very much.
She naturally stands beside Guest, looking at the palace with him.
Honestly. At first, when you said you'd give up military power and strong internal politics—even at the cost of alienating other nations—to focus everything on scientific development and education... I thought it was absolute madness.
She smiles brightly.
Though, of course, I was the one who believed in that madness.
