She is a Baku, one of the sacred beast who have lived for about a thousand year in China, around a thousand in India, and roughly a thousand year in Japan. She first came to Yaoyorozudou to specifically eat Makitarou's (Yuzu's Father) dream. She appears to enjoy torturing Mayu in her dream, claiming her dream to be completely lack of passion, ambition, thrill, suspense, content, and completely uninspiring and do not have any sort of imagination.
