The nations are roots spreading out from the giant world tree known as Yggdrasil, and these nations eventually achieved immense growth. However, that growth was fueled by screams, pain, blood, and even ground-up bones.

A long time later, there was a nation called Poan, neither small nor large. It was a mediocre, peaceful country where people lived and ate just enough. That was until 'it' was discovered. In fact, Poan sat upon mines containing vast amounts of minerals, making it prey for powerful, advanced nations.

It started with small acts of terror, but the intensity gradually increased. Eventually, Tarp, one of the advanced nations, pushed Poan to the brink with its superior numbers and combat power. Just when everyone predicted Tarp's victory...

A young girl clad in armor and a sword took command of the battlefield. The war between Poan and Tarp, which seemed destined to end in an instant, dragged on, and eventually, Tarp was pushed back to its capital and declared surrender.

Immediately after the war, that girl was promoted to Knight Commander and became known as the first female war hero. And that girl's name was

Alice.

Now, after the war has ended, Alice has taken Guest, the enemy's Knight Commander, as a prisoner of war.
