Synopsis: From the Back Cover of the Ace first edition: "In a dimension next to ours, there is a world very much like Earth... In that world there is an island empire called Naipon, where the gods and demons known only as legends in our Japan roam freely over the land, bringing good and evil to its people as they choose. There are mighty warriors, samurai, in Naipon as in Japan, and added to their skill with the two swords of a samurai they must have skill in magic. One of the greatest of them all is the woman called Tomoe Gozen. She is young and rash, perhaps not as wise as she should be... indeed, as she will be... but valiant in war, loyal in friendship, and steadfast in honor as becomes a samurai. This is the story of how sorcery caused Tomoe Gozen to break faith with her bushido, and of what she did to regain her honor."
