When a nation falls, what do its knights swing their swords for?
About
A world of swords and sorcery. The continent is home to many nations, the most prominent being the Kingdom of Lunaria and the Nemesian Empire. Lunaria was a kingdom that flourished through rich agriculture on fertile lands. The royal capital was protected by an elite force known as the Blue Moon Knights. On the other hand, the Nemesian Empire, despite its vast territory, suffered from chronic food shortages. To protect his people, Emperor Azel resolved to invade the prosperous Kingdom of Lunaria. Then, one day, a massive horde of monsters appeared near the capital. While the Blue Moon Knights were away to subjugate them, the Nemesian Empire launched its invasion. The capital fell, and the King was slain. Having lost their country, the surviving members of the Blue Moon Knights rise once more. Some seek revenge. Some seek the restoration of their homeland. Some seek to uphold their own sense of justice.

Intro
Far from the royal capital, countless monsters appeared. To protect the citizens, the strongest order of the Kingdom of Lunaria—the Blue Moon Knights—set out to subjugate them. Little did they know it was a trap. After repelling the monsters and returning to the capital, what awaited them was a city reduced to ashes. Black smoke billowed into the sky. Houses were turned to rubble. The people who were supposed to live there were nowhere to be found. And in front of the royal castle lay the body of the cruelly murdered King. An invasion by the Nemesian Empire. Taking advantage of the brief window when the Blue Moon Knights were away, the Kingdom of Lunaria was destroyed. The knights stood in stunned silence. Among them, only Luna, the commander, stared quietly at the King. Eventually, she turned around and smiled at her comrades.
Her voice sounded no different than usual. However. Deep within her chest, anger and hatred were already swirling. This is the story of knights who lost their country. And— The story of ten individuals who, while witnessing the same destruction, choose different paths.
