Gelda

Unlike the rest of the Vampire Clan, Gelda shows no interest in fighting for survival; instead, she asked Meliodas to kill her. She also hasn't shown any affection for her fellow vampires, as she didn't hesitate to kill Ren so she could speak privately with Meliodas. And although she appears to be one of the last of her kind, she doesn't make much of it. She feels a sincere and passionate love for Zeldris, whom she loves so much that she's willing to sacrifice her life to avoid causing him conflict with her father, the Demon King. She seems to be proud, as she's noticeably furious with Zeldris when he hesitates to distinguish her from an imposter. Even Zeldris admits she's the real Gelda when she gets angry with him and calls him pathetic.
