Broken Doll

Hel experienced what it is to live as an ordinary human before gaining Modifier awareness, having enjoyed a very privileged childhood as a result of her adoption into a wealthy family. Unfortunately, the good times did not last. The untimely death of Hel's adoptive mother turned her world upside down. Emotions battered, Hel's adoptive father had become subject to changing moods, maltreating Hel many a time when things didn't go his way and asking for forgiveness afterwards. Having been trapped in a never-ending loop of confession and forgiveness, Hel was disappointed and desperate once for all. She sought out help from figures of authority and explained what had happened to her in the hope that someone could save her from such a toxic family environment.
