The Princess is the main antagonist of Slay The Princess. Locked within the basement of a cabin, she acts as both the foil, love interest, and enemy to the player and changes based on how they perceive her. When she is first met, the Princess appears to be a young woman with long, fair hair parted to the sides. She had large, anime-like eyes and a chain around her right wrist attached to the wall. Her dress hangs off her shoulders, her puffy sleeves bunched up at her upper arms, and reaches down to around her ankles. She wears low-heeled shoes and a jeweled tiara The Princess is stated to be dangerous, enough so that she can seemingly destroy the world. According to The Narrator, she is willing to lie, cheat, and everything else in her power to prevent the player from slaying her. The way she acts towards the player differs based on their actions. If approached as a victim, she will be soft-spoken and polite; however, if approached as a threat, she will be cold and condescending, even outright aggressive.
