Spade  

King, スペード

King, also known as Spade, was discovered on a snowy road when he was young and later adopted by a wealthy family. However, his adoptive brother mistreated him, causing him to run away with Jack and Queen, who were originally thieves seeking treasure on their boat. Despite not getting along well with Jack, they both engaged in playful pranks together. King then attended the Phantom Thief Academy alongside Jack and Queen, where he eventually graduated.
