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!

The battle against the ruthless Sojo begins! Sojo speaks of Kunishige's enchanted blades and how they only exist to take the lives of others. While the two fighters respect the same man, they walk conflicting paths. As he witnesses Sojo's cruelty, Chihiro's bloodlust begins to build.
