Seven Deadly Sins Diane the gaint

Diane「ディアンヌ」 is the Serpent's Sin of Envy「嫉妬の罪サーペント・シン, Sāpento Shin」 of the Seven Deadly Sins. She is a member of the Giant Clan and is thus much larger than ordinary people, including her fellow Deadly Sins. Her Sacred Treasure is the War Hammer Gideon, which she uses in conjunction with her inherent power, Creation.

During the New Holy War arc, Diane's strength was fully acknowledged by the former King of the Giant Clan, Drole as he himself died protecting her after declaring her as his successor, making her the next potential ruler of the Giants as well as the unofficial Giant Queen. She is also currently the wife to King, who is the current King of the Fairy Clan.
