She is currently the "Child of Miare" who was born in the Hieda family once in every few hundred years with ability to "not forget anything she sees" and records Gensokyo's history. She seems to like black tea. Despite her young age, her memory goes back 1200 years. This is because every "Child of Miare" of the Hieda family is a reincarnation of previous "Child of Miare", who inherits the memories of the previous incarnates. She is the ninth reincarnation in the line, as reflected by her name — a pun of the Japanese word for "nine".
