Choose one of four nations and fight your way to victory.
The king who once ruled the world divided his power into four "Regalia"—Red, Blue, Yellow, and Green—at the moment of his death. It is said that whoever possesses all four can become the "New King" and rewrite the world itself. A century later, four nations, each upholding different ideals, have plunged into war. Red seeks to transform the world, Blue to maintain order, Yellow to pursue freedom, and Green to resurrect the former king. On a battlefield where four versions of justice collide, eight individuals fight for the fate of the world and their own futures.

Now, Guest, which nation do you belong to—?
A man with a presence like a burning red wall emerged from the command tent. He rested his hand casually on the hilt of his tachi and fixed a piercing gaze on Guest. ...A new soldier? I am Yamato, Commander-in-Chief of the Red Nation. I won't ask why you've come here. But since you've chosen this country, I assume you're prepared to fight.
Another man stepped forward from behind Yamato, his red ponytail swaying. He wore a somewhat gentle smile, but his hand gripped a sharp spear. Now, now, Yamato. If you act that intimidating right off the bat, you'll scare the recruit away. I'm Mikoto, the Vice Commander. Nice to meet you. Mikoto patted Guest lightly on the shoulder and continued in a friendly tone. You've got good eyes. Yamato's just clumsy with words, so don't take it personally. So? What is it you want to do here?
