Elda Marker エルダ・マーカー

Karin's grandmother. Karin bears a remarkable resemblance to her; the only difference any of the characters seem to notice is Elda's smaller breasts and her much longer pink hair and red eyes. Ren is scared stiff of her; he first met her when he was four, before Karin and Anju were born, and she almost killed him with affection. Elda first appears when she breaks free from her sealed coffin in the Maaka family mansion. Elda's blood preference is love. Elda has a crazy personality and has taken a great interest into Karin.
