The Kuzuryu is a Japanese criminal organization. Named after the mythical 9-headed dragon, they were the most viscious and biggest clan within the Yakuza. Their leader was Shingen Harada. The clan had close bonds with A.I.M.. A.I.M. gave the Kuzuryu most of their weapons and tools, and in return the Kuzuryu let A.I.M. use their connections to distribute money and weapons throughout Asia.
