Restia is Kazehaya Kamito's contracted spirit. She is a high level darkness elemental spirit in the form of young girl.

In elemental waffe form, she transforms into a jet-black demon sword known as Vorpal Sword—the sword that pierces truth. She is capable of transforming herself to sword form on her own and being wielded by others without forming a contract.
