Arthur Pendragon

Named the king of Camelot after pulling a sword from the stone that hundreds of holy knights could not.

Arthur is a polite, young man who is still adjusting to his role as king. He takes his responsibilities very seriously, but usually undertakes them with a smile and has a very warm, and happy-go-lucky demeanor.

He marched toward the kingdom of Liones with an army of illusions created by Merlin in hopes of meeting with the king; however, he was confronted by Hendricksen who tried to kill him before Meliodas came to his aide.
