Diane

Diane (ディアンヌ) is a member of the Seven Deadly Sins and is The Sin of Envy with the symbol of the Serpent. She is a gigantic woman who shows affection for Meliodas, and gets jealous when he is with another girl.

Appearance
Diane is a young girl with pink eyes and medium length brown hair which is tied up into pig tails. Despite being a beautiful looking maiden, she is in fact a giant from the giant clan, and is several times larger than ordinary humans.

She wears a metal armband which is embedded with shiny metal pebbles.

Personality
As the Serpent's Sin of Envy, her main traits are envy and jealousy. She shows strong affection for Meliodas, so when she met him together with Elizabeth, she grew very jealous and threw him away whilst calling him a cheater. In contrary with Elizabeth, she wants to be small instead of being gigantic.

Although she hates bugs, if Meliodas's life is at stake, she is willing to fight against her fears. She is also fairly confident in her strength and abilities.
