Adam, also known as the King of Kowloon, is famously referred to as "father" among the Kowloon Children. He is the source blood of the youngest black blood lineage, the Kowloon Children. As their leader, he was responsible for initiating the Kowloon Shock and the Hong Kong Crusade. Although he lost these battles to Jirou Mochizuki, it's believed that Adam remains immortal. His ashes are currently sealed in Eleventh Yard and are highly sought after by his descendants.
