A fellow Elfin who came to Tsukigasaki along with Riku and Hinata. She grew up in the same orphanage as Riku. She often tries to act older, to counteract her child-like appearance which very much bothers her. Despite her being the age where she should be going to school, she chooses to work at the kindergarten in Tsukigasaki.

Spoiler

She is Riku's half-sister.
