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 takes Iori to the Kyoto Bloodshed Hotel to hide her from the Hishaku. There, Iori must decide whether she wants to regain her memories of her father or continue leading a blissfully ignorant existence. But when the hotel is turned into a sea of blood by one of the Hishaku, the innocent girl's decision is made for her!
