An unseen voice opens each episode with "Once upon a time," framing events within a fairy tale for Gold Crown Town. This narration recounts how Drosselmeyer, the author, died before finishing "The Prince and the Raven," allowing his characters to escape into reality. It details the Prince shattering his own heart to seal away the Raven, scattering shards that merged with townspeople and twisted their stories. Serving as an omniscient perspective on the interplay between story and reality, the narration directly addresses the consequences of Drosselmeyer's unfinished tale. It observes the town transformed into a place "where the fantastical was no longer fantastical" after the heart scattered. It foreshadows key plot elements, such as Princess Tutu's fate to vanish if she confesses her love, and contextualizes character motivations through allegorical references to tales like "Sleeping Beauty" and "The Red Shoes." Specific episode narrations mirror character arcs: one compares Fakir to a warrior who killed his friend, reflecting his protective yet controlling bond with Mytho. Another likens Rue's possessiveness to a maiden binding her lover with chains of love. During Mytho's corruption by the Raven's blood, the narration explicitly references the "Swan Lake" dynamic between the Prince, the swan maiden (Tutu), and the black swan (Kraehe). The language consistently underscores the tragedy of inescapable stories, questioning if characters like Cinderella's maiden found love or merely fulfilled a plot. In the season one finale, the narrator breaks the opening format to speak during the climax, addressing the audience directly about the unfolding tragedy. It ultimately frames the entire series as Drosselmeyer's influence, concluding with his departure to seek new stories after the Raven's defeat. Throughout, the narrator remains a disembodied voice without personal history or development, functioning solely as a storytelling device that bridges the author's intentions and the characters' struggles.
