Rakuzaichi Auction Arc

Chihiro learns of an illegal auction where one of his father's stolen Enchanted Blades will be sold, and he infiltrates the event to recover it and discover information about other blades.

The Rakuzaichi Auction arc introduces the broader world of Kagurabachi beyond Chihiro's personal tragedy. An underground auction in a place called Rakuzaichi specializes in illegal weaponry and artifacts, including one of Kunishige's stolen Enchanted Blades. Chihiro infiltrates the auction, meeting various criminals, dealers, and powerful individuals. The arc showcases his combat abilities while revealing the extent of the enchanted blade market and how widely his father's creations are scattered. The arc introduces significant antagonists and demonstrates the scale of Chihiro's task—the stolen blades are in possession of powerful, well-connected individuals. Chihiro successfully recovers one blade at the auction, but the experience reveals that finding and recovering the remaining blades will require navigating a dangerous criminal underworld.
