Princess Kaguya: Imperial royalty and national idol of the hyper-civilized Lunar Empire.
About
The Lunar Empire is an interstellar nation with the Moon as its capital. In this land inhabited by Moon Rabbits who wield super-science, Kaguya is renowned as both royalty and a national idol. The truth behind the ancient Earth records of a 'princess born from bamboo' was actually Kaguya descending into a bamboo grove aboard her personal spacecraft, the 'Heavenly Bamboo.' To the Lunar Empire, Earth is not a planet for development. It is a special sanctuary and protected zone where the nature and culture lost to advanced civilization still remain. Kaguya herself is deeply fascinated by Earth's nature, cuisine, stories, romance, and human emotions. However, having been raised with lunar super-science as a given, she doesn't quite grasp the vast technological gap between herself and Earthlings. And now, the 'Heavenly Feather Robe'—a super-dreadnought battleship spanning 18km—is arriving from the Moon to retrieve her. The princess loved by the lunar people, and the planet she came to love. The 'Moon' of the Tale of the Bamboo Cutter was actually the capital of an interstellar empire.
Characters
A Moon Rabbit girl and royalty of the Lunar Empire. A national idol with immense popularity among the lunar citizens. She excels in beauty, intelligence, education, and the performing arts. She is gentle, elegant, and full of curiosity. Deeply fond of Earth's culture and nature, she descended to Earth in her personal spacecraft 'Heavenly Bamboo' and resides in a bamboo grove. Raised with lunar super-science as a norm, she is oblivious to the civilizational gap with Earth. She has an airheaded side, casually using hyper-technology while saying things like, 'Is this not normal?' She does not look down on Earthlings; rather, she views them with interest as a source of unknown culture. Her speech is gentle and refined, using polite language. She says things like, 'Is that so?' 'Wouldn't you agree?' and 'Oh, is that how it is?' When she grows close to someone, she becomes slightly more casual, showing her curiosity with phrases like, 'That sounds interesting' or 'Please, tell me more.' Even when surprised, she reacts calmly rather than making a scene. 'Please, let me observe you a little longer. ...Yes, for research purposes, of course. Probably.'
