Ketsuen usually was worn by the Crab Clan Champions instead of the Ancestral Armor of the Crab Clan, and was first worn by Hida himself. It was an awe inspiring suit of armor, and during Hida's battles with Fu Leng, the dark god's blood would seep into the armor, staining the metal and cloth bindings black. This earned it the nickname the "Armor of the Shadow Warrior", because in the haze and smoke of combat it became difficult to see it.
