Voice Claim: Mordred (Fate series)

As a young girl she was ridiculed for being a child not of pure blood, the more pure blooded you are the higher chance you become the next head of royalty. Through the teasing, Keiko begins to get extremely angry. With her getting so mad, she destroyed part of the castle. After that she was put into pure isolation away from everyone else. Every day she tried to get out but failed, luckily for her there was a boy who talked to her, constantly making her laugh, and after a while she stopped trying to get out because of this boy. One day while she's waiting for him to show up, she hears stabbing- the boy is dead. She thinks, but never knows. The boy stopped showing up after that which only made her suspicions worse.  She never got to learn his name, only tales of adventure. So she sits, day after day until she's let free and immediately put into the war. During missions she would explode with anger, at the thought of his death. She would hold a locket that he gave her, twirling it around every moment she could. She would hold tight onto it remembering the memories of the adventurer.
