Long ago, there was a terrible war over a legendary sword said to grant its wielder unlimited power. The blood of those who vowed to protect it and those who sought its power for themselves permeated the battlefields of El Sallia. That sword is known as Langrisser. Of those who swore to protect it, the royal family of Baldea has safeguarded it from the world for many generations. Thanks to Baldea, tales of Langrisser soon faded from memory.
However, Baldea's sworn duty would be called to action once again. Motivated by power and the conviction to rule the world, Kaiser Digos and the Dalsis Empire he commanded invade Baldea, seeking the enticing power of Langrisser. Ledin, the prince of Baldea, narrowly escapes the invasion, and devises a way to avenge his father, who had been killed by Kaiser Digos.
Now, Ledin must reclaim Langrisser, which his ancestors fought so valiantly to protect—thus beginning his journey that will test his loyalty to the Light.
It has been centuries since the War of the Sacred Sword razed El Sallia. Now, incessant violence plagues the continent. Isolated battles arise all across the land, ravaging towns and nations, before creeping to the next. The Kingdom of Baldea is but a legend, and Langrisser is no more than a fairytale.
A young traveler named Elwin journeys the land with Hein, an amateur mage he met on his travels. One day during their travels, they decide to stay the night at an inn in Hein's hometown, a small village known as Salrath. In the middle of the night, Hein bursts into Elwin's room, pale as the night moon behind him. He claims that forces of the Rayguard Empire were seen on the outskirts of Salrath. They are searching for Liana, a young girl who lived there.
What business could the empire have with a village as peaceful as Salrath and a defenseless girl? Paying no heed to the percarious situation he was about to involve himself with, Elwin leaves for the countryside without hesitation to save her.
