The engagement between Scarlet, a noblewoman from a ducal family and the Second Prince Kyle was abruptly terminated during a ball. She had been falsely accused of harassing Terenezza, daughter to a baron, whom the prince adored greatly. Despite being condemned by everyone around her, she bore all manner of crimes until she finally decided enough was enough. As Scarlet prepared to leave, she turned to Kyle and asked for one final thing. The crowd erupted in boos and jeers while that good-looking guy hurled insults at her. In response, Scarlet spun her palm like a drill, staining the ballroom floor with blood.
