King

King, whose real name is Harlequin, is the Grizzly Sin of Sloth in The Seven Deadly Sins, marked with a bear above his left ankle, and the 1,300-year-old third king of the Fairy race. He left the Fairy King's Forest 700 years ago to rescue his friend Helbram from humans, lost his memory and was saved by Diane. On recovering it he learned Helbram had caused it and had to kill him; he then erased Diane's memories of him and was sentenced by Liones to 1,000 years' imprisonment, while the forest was later destroyed by a demon that killed his sister Elaine.

He rejoins the Sins once he learns the truth of her death, and stays devoted to Diane, who eventually remembers him. He can fly and move objects without touching them, and wields the Spirit Spear Chastiefol, which takes forms from a pillow-shield to a giant flower that fires a beam. He won a 2014 popularity poll with almost four times the votes of second place.
