King

The fairy king Harlequin (nicknamed King) is one of the Seven Deadly Sins, also known as the Grizzly's Sin of Sloth. He is in love with the giant Diane, but Diane does not remember the connection they shared in the past. King doesn't have much in the way of physical strength, but he carries around a giant pillow called Chastiefol that can change into many different forms to aid him in battle. He also has a pet "dog" named Oslow that helps him transport long distances quickly. 700 years ago he was king of the fairy forest until he left attempting to save his friend. King lost his memories and never returned, leaving his sister Elaine to fulfill his duties in his stead. Elaine was eventually killed, and King erroneously blamed Ban for her death.
