Natsuki RemEdit

While she initially distrusts Natsuki Rem, believing her to be the thief who stole her Light Sphere, Zarestia's childish nature leads them to develop something resembling a mother/daughter, or older sister/younger sister, relationship. As a result of their deep bond of mutual affection, Zarestia decides not to kill Rem even after she recovers her full power and murderous urges. Zarestia holds Rem in higher regard than anyone else.
