To save her inn, Fumiku must delve into that city in search of answers. She will not go alone. A patron of her establishment, a samurai warrior from a distant kingdom will accompany her. He is battle tested and fearless. It seems that death itself cannot stop him. Together, they have the chance to stop a rising army and to learn the fate of Fumiku's family. In order to do so, they will they placate the cryptic wishes of The Lord of Xu.

"The Lord of Xu" is a return to the weird world of the red sun, an underworld filled with monsters, magic and high adventure. This place is the stomping ground for the warrior Haiyu, the samurai of Hell who is sworn to Emma-O to find the world's center and plant Hell's standard there. Although fourth in the Samurai of Hell series, this 7000+ word tale stands alone and serves as a great entry point to the series.
