Elda Marker

(voiced by Yuri Shiratori)

Weapon[s]: Black Umbrella

Elda Marker is the mother of Henry Marker and the paternal grandmother of Karin Maaka. Elda was born in Transylvania, where she fell in love with the human Alfred. After Alfred betrays her due to circumstances beyond their control, Elda curses humanity and moves to Japan, where she is imprisoned by Carrera Marker in her coffin prior to the birth of Karin Maaka. Due to Alfred's betrayal, Elda does not show respect for humans, and drinks blood as she sees fit, leading the other Maaka family members to perceive her as a monster. She is generally loathed by Carrera, possibly based on the classic mother vs. daughter-in-law conflicts. Elda is the only person feared by Ren, whom she almost killed with affection when he was but four years old. She managed to get on Anju's bad side within five minutes after they were introduced - by hugging Karin and crushing her breasts. Only Henry and Karin seem to be concerned with Elda's wellbeing, although even they are taken aback by some of her actions.

Elda bears a striking resemblance to Karin, so much so, in fact, that Karin's close friends mistake her for Karin—the only noticeable physical difference is the hair color, hair length and bust size. Elda appears slightly envious of Karin's bust. Elda's bust itself bears an unusual scar, a relic of the betrayal of Alfred. Vampires are not supposed to sport scars because of their rapid regeneration. Probably the presence of the scar is due to Elda's wounded heart.

Like other normal vampires, she takes away the emotions of humans she bites. But unlike the other vampires mentioned in the story, Elda is a vampire who has a taste in blood some humans consider bad. When she bites a human, she takes away their love. After she was released from her coffin she bit dozens of humans in a park and was spotted by Kenta Usui. She also bit some schoolmates of Karin and attempted to bite Kenta too, even though she was only trying to prevent Karin getting hurt like she did. In this occasion Elda run into Winner and found out of Karin's condition. She leaves in search for a cure.
