Set in 19th-century Japan, this supernatural story follows Konosuke Ryudo, an impoverished samurai who lives under a bizarre and debilitating curse. Because metal of any kind physically bends and repels away from his touch, he cannot wield a traditional steel katana or even shave his head.

Although she brings a massive dowry and deep affection, she also carries secrets that pull Konosuke into a dangerous world of ancient magic and occult forces. Readers will enjoy how the plot balances gritty historical realism with haunting folklore and emotional character growth. This seinen series explores the true meaning of honor through stunning, expressive artwork and a gripping narrative.
