Rough translation:
Story
A long time ago, there was a peaceful kingdom named Aretha on Arterra.
Two daughters were born to king Riverton of the Aretha kingdom.
Riverton, wishing for the welfare of his daughters, gave them the two rings Gold Cat's Eye and Silver Cat's Eye.
But then the evil king Howard began to assault the happily celebrating Aretha kingdom.
The Gold Dragon who served Howard suddenly appeared during a banquet, coming to steal one of the daughters.
The desperately resisting Riverton and the Aretha army were forced into a bitter battle, and about to be defeated.
Riverton used his last strength to seal the Aretha temple and allow his one remaining daughter to escape.
Now, more than ten years have passed by.
