Narração is the disembodied narrator of the anime, serving as an off-screen voice that introduces episodes, provides exposition, and comments on the unfolding events. This character has no physical form or personal identity; it exists purely as a storytelling device. The narration is delivered in a calm, authoritative, and often somber tone, which sets the dark and melancholic atmosphere of the series. Its primary function is to guide the audience through the episodic plots, offering background context, summarizing previous events, and framing the moral dilemmas faced by the main trio. The narrator has no interactions with the other characters and no personal development or arc; it remains a constant, omniscient presence throughout the series. Notable abilities include an all-knowing perspective on the story and the capacity to deliver information with a measured, ominous cadence that reinforces the themes of isolation and the struggle for humanity. In the 1968 original series, the opening narration was performed by different voice actors across episodes, while in the 2006 remake the narration was handled by a single voice actor. The narrator does not have a background, personality traits beyond its narrative voice, or relationships with the cast, as it is not a character within the story itself.
