The story focuses on Ru's journey of self-discovery and her sacrifice to save the prince, Fakir, whom she loves. She ultimately chooses to live as the "Princess Tutu" persona, a powerful and selfless entity, rather than pursue a romantic relationship.
While there is a strong romantic undercurrent between Ru and Fakir, the story concludes with them not ending up together in a traditional romantic sense. This leaves room for interpretation regarding the nature of their relationship and the possibility of their bond evolving in the future.
