Chihiro Rokuhira's father, Kunishige, is the most famous swordsmith in the land. Thanks to his six enchanted blades, the war that has been gripping the nation ends, and peaceful days follow. After the war, he retrieves all six blades and hides them in the cellar of his workshop--but sorcerers raid his home and leave Kunishige dead in front of Chihiro. Many years later, Chihiro wields Kunishige's seventh and final enchanted blade on a mission to retrieve the stolen swords!

Chihiro and Hakuri head to Kokugoku hot spring, the sanctuary where the enchanted sword bearer is being held. On the way, they meet up with Uruha, the bearer of the Kumeyuri, but then they encounter Hiruhiko from the Hishaku. Hiruhiko has a strange relationship with Chihiro. Isolated from society, they burn for each other's lives and clash!
