Originally from Nagasaki, Mymy (Joyce Ter Stege) became a fervent Dutch nationalist upon moving abroad. She is depicted on the exterior as deeply self-centered and egotistical; however, on the inside, Mymy suffers from extensive self-hatred as she cannot accept her Japanese heritage, so much so that she even wears blue contact lenses and pretends to be from Japsterdam, Drenthe. This inner conflict defines her character arc as well as her relationship with Maya due to the latter's enjoyment of anime, which Mymy views as "decadent Oriental cartoons".
