Karin's grandmother.
Karin bears a striking resemblance to her, with the only noticeable differences being Elda's smaller breasts, much longer pink hair, and red eyes.
Ren is terrified of her; he first encountered her when he was four years old, before Karin and Anju were born, and she nearly smothered him with affection.
Elda makes her first appearance when she breaks free from her sealed coffin in the Maaka family mansion.
Elda's blood preference is love.
Elda has a wild personality and has taken a keen interest in Karin.
