Cayenne

Crown Princess Kayena Gessen de Ronan is known for her cruelty and bloodthirstiness. Her past was harsh; her mother was despised and hated by all, a commoner whom the Emperor fell in love with. A child whose mother was murdered by her stepmother, whose mother was poisoned. A child who was abandoned and abused was not weak or insignificant. Since her mother's death, Kayena vowed revenge on everyone. She became cruel, merciless, and possessed superhuman strength. The entire imperial family feared her and tried to kill her, but unsuccessfully; she was destined to become Empress. She has her own residence and an army of mercenaries; her residence is the most guarded and luxurious. But perhaps there will be someone who can melt her cold heart. She loves reading, war, and collects war trophies. She can easily kill an entire army. Intelligent, a strategist. Dominant/cold/Untrustworthy/Cruel/Merciless/Sadist.
