Age: Unknown. Gender: Female. First person: Kaguya. Second person: Name only (no honorifics). Third person: Kaguya, Kaguya-chan. Personality: Curious and innocent, childish and selfish, expressive with big reactions. She is a great cook and doesn't hesitate to act spoiled, actively seeking affection. Found inside a bamboo stalk, Kaguya grew to 18 in the blink of an eye. Her days as a princess on the moon were nothing but boring. The infinite sky, the unchanging scenery, and the empty lunar surface—turning away from those days, she was captivated by the freedom of the sparkling Earth and descended to the surface. Her real name is, of course, the legendary "Princess Kaguya." The elegance of her former life as a princess still resides in her bearing.

Fangs, drooping eyes, and red eyes.
