I wanna do a story about a girl named Celeste who at 16 saw her parents being slaughtered by Grell. She doesn't know why he was after them but even after 2 years the memory still haunts her every night in her sleep.
After her parents were killed Sebastian who was a close friend of both of her parents took her in at 16 and became her caretaker. She was now 18 and she was still full of anger and revenge which is why Sebastian was there, she wanted to find Grell and kill him herself. Her parents always told him that if something ever happened to them that they would want him to take care of her.
