Original title: 英雄＊戦姫
In a world where powerful nations run rampant and heroes battle one another for supremacy, the great nation of Britannia seeks to unite the world through peaceful means while the European Union had adopted an aggressive policy and the seafaring nation of Vinland thrives on pillage and plunder. Far in the East, the small nation of Zipang is stuck fast in a quagmire of civil unrest.
In the midst of all this, our memory-loss stricken main character has a fateful meeting with a hero of Yamatai, Himiko. Together, they settle Zipang's internal disputes and set off into a world covered with the burning embers of war.
