Hanyuu Furude

Hanyuu is the mysterious "transfer student" in Matsuribayashi-hen. She has a pair of dark colored horns on her head, one of which is chipped slightly (however, no one seems to notice or mention them, with the exception of Takano, who calls her a "monster").

In fact, she has appeared to Rika all her life, but only in Matsuribayashi-hen and Miotsukushi-hen did she gain the power to interact with others, posing as a distant relative of Rika's and given the name "Hanyuu Furude." Like many of the characters, she can be frightening when angered, and with her spirit-like nature, her appearance can change with her mood until she takes a physical form.

She is very meek and often makes the noise "Au au, au au…" when she is nervous or uncomfortable, or sometimes while trying to make a point. She also tends to end her sentences with nano desu (なのです?, lit. "it is so").
