Gelda

A woman from the vampire clan and Zeldris's lover. They are mutually in love, and she is someone Zeldris truly wants to protect. As a vampire, she possesses high regenerative abilities, and because she drinks Zeldris's blood, she cannot die even if decapitated. She was about to be executed by the Demon King, who detected the vampire clan's rebellion that took advantage of Meliodas's betrayal. However, Zeldris, who was ordered to execute her, deceived the Demon King by sealing her, putting her into a 3000-year slumber. Later, her seal was broken about 12 years before the revival of the Ten Commandments, but she, despairing over her fate with Zeldris, asked Meliodas, who came to subdue the clan, to kill her. However, Meliodas did not kill her, and she was sealed again, only to be unsealed by him after the end of the Holy War in the present day. She then left to search for the missing Zeldris but appeared before the Sins fighting the Demon King, who had taken over Zeldris. She bit the Demon King's neck, easily infiltrated his mental world, found the real Zeldris among countless illusions, and rescued him.
