This is an alternative version of Eiyuu*Senki, with a new storyline. It takes over its cast while adding additional heroines and powers up its system.
In the ancient far Eastern country of Zipang, a storm is brewing. The country enjoys a period of peace and its unique culture flourishes thanks to the isolationism imposed by the great Ancient Hero, Yamato Takeru. But the heart of one lone hero, Masamune Date, burns with the fire of ambition in this seemingly content land.
After coming across a young man, void of all his memories, on the shores of Zipang, she puts her plans in motion to challenge Takeru. Should they succeed, they will force open the country’s borders and begin an epic adventure filled with exotic lands, fierce battles, and new conquests!
