The artificial celestial maiden that is the manager of the experimental subrealm at the bottom of the sea in System Takamagahara, popularly known as the Dragon Palace. Otohime is believed to possess a beauty that is beyond anything in this world as she entertains and dances with the fish. She was born for the sake of developing and verifying techniques meant to seal painful memories that deeply scar people's minds so that they can heal. She has so few expressions it's as if she has no emotions. However, this is in consideration for those whose minds are pained from even being smiled at, so by no means is Otohime emotionless. As proof of that she has deep sympathies for those who are hurt and those who are devoted, and she has an appropriate amount of anger towards those who disturb the peace. In emergencies she will turn into a dancer who fights on the front lines with her fish-type companion bots. She has the respect of those who live in difficult-to-describe dirty rooms as the leading cleaning consultant in Tokyo.
