After taking good care of her health and living for a long time, Tewi became something more than an ordinary rabbit. She leads the Earthborn rabbits living in Eientei. Her impetuous temperament makes her seem more like a fairy than a phantom. Humans who lose their way in the bamboo forest around Eientei sometimes catch a glimpse of Tewi. Those who see her are able to find their way out without fail, so she is considered a guide of the forest. It's a shame that they waste the fortune given to them by Tewi on such a small thing, but humans are too clueless to notice their mistake. (Source: Touhou Wikia)
