Kagurabachi, Vol. 4 by Takeru Hokazono

Chihiro's cursed past sends him down a quest of bloody vengeance!

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 Shinuchi—the strongest sword ever produced by Kunishige—is up for auction. Chihiro’s on a quest to reclaim the famed blade, but first he’ll have to deal with the auction’s guards, who are sworn to protect the auction at all costs. Undaunted in his quest for vengeance, Chihiro vows to cut them all down!
