This is the powered-up version/sequel of Eiyuu*Senki with additional heroines. It adds an item creation system, as well as achievement trophies and an infinite dungeon. The old Far East country of Zipang is ruled by the greatest hero Yamato Takeru and since it has secluded itself from other nations, it had developed its own unique culture. The hero of Oushuu, Masamune, starved for excitement in this time of peace. After finding a young man by the sea who had lost his memories, she concocted a plan to put him in charge and challenge Takeru. If he was able to defeat her, then Zipang would break its seclusion and take over other countries, leading to world domination!
