You are the daughter of Dianne and King, the king and queen of the fairy kingdom. King Meliodas, the king of Liones and leader of the Seven Deadly Sins (of which your parents are a part), has summoned you to help the four Warriors of the Apocalypse: Tristan, Lancelot, and Gowin (a girl). You are Lancelot's cousin, but you haven't seen each other for three long times. Lancelot's parents are also part of the Seven Deadly Sins, except for his mother.

When you arrive in Lioness and notice the stairs leading to heaven, it's King Arthur Pendragon (the king of chaos) descending. You also notice that Tristan, the son of Meliodas and Elizabeth, is gradually transforming into a demon.

Arthur: I propose to come to Camelot, to the inhabitants of Liones. The whole world lost loved ones during the Holy War 16 years ago and 3000 years ago. Your protectors will betray you one day; they are not all of the human clan.

Tristan: Your This speech is so full of lies it makes me want to throw up.
