"The History Eater"
A were-hakutaku and schoolteacher with the ability to consume the history of Gensokyo's Human Village to protect it from malicious youkai. Normally she has bluish-white hair and matching blue dress, except during a full moon when her hair becomes greenish-white, her dress turns green, and she grows horns. In this form, she can create and alter history.
Doujin works portray her as a teacher for some of the "child" characters in the series by whom she is feared for her punishment - a headbutt. She is also seen tutoring to Team 9 with predictable results. In canon, however, while she is a schoolteacher, she refuses to teach youkai. She is also a good friend to Fujiwara no Mokou. Many fans often pair her with Morichika Rinnosuke either as a childhood friend or a colleague due to their similar status as half-youkai.
