Nayotake no Kaguyahime is a celestial princess who appears in the Heaven Chapter (Tenjōhen) of the Utsunomiko anime, which is based on the light novel series by Keisuke Fujikawa. Her name directly references the legendary Princess Kaguya from The Tale of the Bamboo Cutter, and she originates from the moon or the heavenly realm. In the story, she is the primary figure that the protagonist Utsunomiko seeks after he ascends to the celestial world. However, upon their reunion, it is revealed that she has lost all memory of her time on Earth and of Utsunomiko himself, making her distant and unaware of the bond they once shared. Her amnesia drives much of the conflict and emotional weight of the Heaven Chapter, as Utsunomiko struggles to restore her memories and rekindle their connection. Her personality is portrayed as ethereal and aloof, reflecting her celestial nature and the gap left by her forgotten past. She holds a deep significance to Utsunomiko as a figure of love or profound companionship from an earlier part of his journey. While her own motivations are not heavily detailed, her role is that of an emotional anchor and a goal for the protagonist. As a being from the heavens, she likely possesses divine abilities, though specific powers are not elaborated in the available material. Her development centers on the potential recovery of her lost memories and the resolution of her relationship with Utsunomiko.
