The Cray Trading Company was a trading company of dubious reputation founded and run by former Scarlet Moon strategist, Graham Cray following the death of his son in the Small Border Village incident of SY 299. While also making profit, Cray Trading Company also served to gather information about the Rune of Punishment which Graham Cray was endlessly searching for. To that end, ninjas and assassins such as Ramada, Akaghi and Mizuki were hired by Cray.
