Better known as the King of Kowloon, and known as "father" to the Kowloon Children, Adam is the Source Blood of the youngest bloodline of black bloods, the Kowloon Children. He is responsible for the Kowloon Shock and the Hong Kong Crusade. During the crusade he was defeated by Jirou Mochizuki, but presumably immortal, his ashes are sealed in Eleventh Yard and are highly sought after by his children.
