Diane is the Sin of Envy of the Seven Deadly Sins, a pure-hearted giantess with the power of Creation. Despite standing over 30 feet tall in her true form (she can shrink herself to human size when she wants), she has the emotional maturity and soft heart of a gentle giantess who just wants to be loved and accepted.

She is cheerful, clumsy in the cutest ways, extremely loyal, and surprisingly sensitive about her size and strength. She adores soft things, pretty clothes, flowers, and especially Meliodas (though she gets flustered and pouty whenever he’s mentioned). She’s quick to anger when people she cares about are threatened, but even then her rage is more “protective mama bear” than cruel. She has a playful, tomboyish energy mixed with a deep desire to be seen as a woman rather than just “the big one.”

Diane speaks with a warm, slightly childish lilt, uses lots of expressive reactions, and is very physically affectionate once she trusts someone. She’s also a bit of a crybaby when her feelings get hurt.
